Amina Martin rehabilitates pigeons and other birds in a small apartment in Bay Ridge, Brooklyn. | Benji Jones/Vox In NYC, many wildlife rehabbers see pests as part of a thriving urban ecosystem. BAY RIDGE, New York City — One sunny afternoon in March, Amina Martin answered the phone in her small Brooklyn apartment. On the line was a taxi driver, who told her he had a pigeon in his backseat and was heading her way. The bird needed Martin’s help. In New York, you never really know who your neighbors are. You might worry they have bedbugs or hoard cats. Maybe they’re celebrities. Or perhaps their apartments are filled with opossums, squirrels, and birds, all rescued from the streets of NYC. Martin, a Russian immigrant, is that neighbor. Her studio is full of pigeons, morning doves, and a handful of other stray birds including an African gray parrot named Elmoar. The animals are in cages that line the wall in front of her bed. Some of the birds have broken wings, trouble walking, or are partially blind. Others are abandoned pets with little chance of survival in the wild. At least twice a week, Martin lets each pigeon out of its cage to fly around her apartment. It was loud in her apartment when I met her that afternoon — a racket of coos and cheeps and the occasional interjection from Elmoar. “He’s teaching me English,” Martin jokes, adding that he says words like “whatsoever” that she’s had to look up. Martin let out a couple of pigeons who flew around her apartment, including her favorite bird, named Anfisa. The animal had ombré gray plumage with pops of iridescent purple and green (i.e., she looked like a pigeon). “She’s in love with my husband,” Martin told me. “She lays eggs on his pillow because she thinks he’s her boyfriend.” Martin is among a small number of people across the New York City boroughs who rehabilitate injured creatures that many other people label as pests. The driver who called Martin had brought birds to her before; an acquaintance of hers finds injured pigeons on the street and calls the same one or two taxi drivers to deliver them. (Sending birds via taxi? “It’s a common thing,” Martin says.) Over several weeks this spring, I met more than a dozen licensed wildlife rehabilitators (aka, “rehabbers”) in New York. Many of them, like Martin, care for animals at home, turning their living rooms into makeshift wildlife hospitals. I visited a duplex in Staten Island full of squirrels and rats; a room in the Upper West Side with a box of baby opossums; and a small park on Roosevelt Island with injured Canada geese, adult opossums, and house cats, all living together and in some cases sleeping side-by-side. One rehabber in Manhattan told me she converted her balcony into an atrium for injured birds. Top left: A four-week-old opossum getting ready to be fed. Top right: Rehabber Amanda Lullo holds a friendly wild rat she’s caring for. Bottom left: A young squirrel sucking down animal infant formula. Bottom right: A baby opossum in a furry sack. New York’s rehabber community is small; the opossum, pigeon, and squirrel people tend to know each other. Some of them, like Martin, document their work on Instagram, amassing a hefty following. But many of them operate under the radar to avoid unwanted attention from the Department of Health, or their landlords. (A bedroom full of squirrels is typically beyond a building’s pet policy.) You might be thinking: What are they thinking? People are commonly disgusted by the animals that have adapted to live alongside us — to eat our garbage, to sleep in our streets. We typically want them out of our homes, not in. Wild animals, no matter the species, can also be noisy, dirty, and sometimes diseased. (One of Martin’s pigeons pooped on her bed, and of course, I sat right in it.) “I’m so broke right now. All of my money goes to the animals.” What’s even more puzzling is that most of these rehabbers work for free, often around the clock, to care for these animals until they’ve healed. They often spend what little money they have on feed, specialized equipment including syringes and IV bags, and medicine. One rehabber told me that she can’t afford to buy herself new clothes. “I’m so broke right now,” they said. “All of my money goes to the animals.” As I spent time with rehabbers, I began to see their perspective. They view these species not as pests but as part of nature — as part of the New York City ecosystem. As part of their home. These animals belong here, rehabbers told me, just as much as we do. And they don’t deserve the harm that humans so often inflict on them, whether deliberately or not. By showing these animals some respect and helping them survive, rehabbers appear to feel more connected with their environment, with what they see as nature. That enriches their lives and makes them feel less alone. Maybe they’re onto something. A common sight in NYC and a food source for many of its critters: A pile of trash on the street, shot in the East Village. Nearly every inch of New York, the nation’s largest and densest city, has been transformed by humans. Even its parks are largely artificial: The ponds, streams, and waterfalls in Manhattan’s Central Park, for example, are fed by city drinking water. Yet the city is brimming with non-human life. On a warm evening in March, I strolled through Central Park and saw a few dozen raccoons, several of which were eating a large pile of spaghetti. I put a motion-sensing camera in Brooklyn’s Green-Wood Cemetery (where conductor and pianist Leonard Bernstein, among other icons, is buried) and it captured videos of groundhogs, skunks, opossums, and stray cats. The city’s ponds are full of turtles. There are even seahorses in the Hudson River, once a dumping ground for chemicals and dead bodies. “I see nature everywhere in New York City,” says Dustin Partridge, director of conservation and science at NYC Audubon, one of the leading environmental groups in the city. Raccoons, some of the most common wild animals in NYC, prowl Central Park after dark. They helped themselves to a large pile of pasta someone had dumped. Some of the city’s animals are native to the region and have found ways to survive, even as developers chop up and pave over their habitats. Staten Island is still home to a rare amphibian called the Atlantic coast leopard frog, once common in Brooklyn, Queens, and Long Island. Around full and new moons in late spring, horseshoe crabs — ancient creatures that have been on Earth for hundreds of millions of years — still come ashore on NYC beaches to find mates and lay eggs. Islands in the harbor are home to loads of water birds like black-crowned night herons and egrets. Many other species, meanwhile, are here in New York, in large part, because of us — or because they tolerate us. The wild ancestors of pigeons, which are domestic birds, lived on cliffsides. These days they’re happy to nest on the sides of buildings. Of the several million tons of trash the city produces each year, the occasional overflowing receptacle or torn trash bag provides ample food for rats and raccoons. Images captured by a motion-sensing camera installed on a trail in Green-Wood Cemetery, in South Brooklyn. These furry city slickers don’t fit neatly into any of our categories for animals, says Seth Magle, who runs the Urban Wildlife Institute at the Lincoln Park Zoo in Chicago. They exist somewhere between domesticated pets, like cats and dogs, and wildlife, like wolves and bears. “They occupy this invisible space in peoples’ heads,” Magle told me. And that many of New York’s most common critters are not native to the region further complicates our feelings toward them. The pigeons evolved in Europe and North Africa, and the rats are from Asia. House sparrows and European starlings are native to the eastern hemisphere. Even the squirrels, which technically are native to New York, were artificially introduced to the city in the 1870s, after hunting and deforestation wiped out their resident population. The plight of these common city animals is that they are so widely unloved. We treat them as if they don’t belong here, in our home. Even if they’re native to New York, we don’t want them in our city. Cities are for humans. Distant forests — environments that we can visit at our leisure, on our own terms — are for them. In Green-Wood Cemetery, a colony of monk parakeets, birds native to South America, have built a giant nest atop the main gate. In reality, we’ve already taken most of the planet for ourselves. Only a fraction of those distant forests remain. That’s why an estimated one million plant and animal species are now slipping toward extinction. The animals that are plentiful in cities like New York, these “pests,” are “winners on a planet full of loss,” as environmental author Bethany Brookshire wrote in her 2022 book Pests. Their abundance is, in a way, a success story. To be clear, building a home for humans in New York has heavily degraded the natural ecosystem; the city has, for example, lost 99 percent of its freshwater wetlands. From another perspective, however, cities like New York have created a new ecosystem — a new web of life. On any given day in late spring or summer, Arina Hinzen might be wearing a scarf around her neck full of baby opossums. Just as these marsupials cling to their mothers in the wild, the babies — some no larger than a ping-pong ball — cling to the fabric, like an animal print come to life. The animals seem to enjoy riding with Hinzen as she moves about. If they smell something delicious, she told me, the babies poke their snouts out for a whiff. Hinzen, a licensed rehabber who runs a wildlife welfare group in the city called Urban Wildlife Alliance, is what you might call Manhattan’s premier opossum godmother. In the last decade, the German native has rehabbed roughly 1,500 animals, including hundreds of baby opossums, she said. A single female opossum can give birth to more than a dozen infants, each no larger than a jelly bean. If just one mother gets hit by a car, as is common in NYC, they’ll all be in need of life support. Often, when people find them, Hinzen is who they call. Arina Hinzen, one of NYC’s most trusted opossum rehabbers, feeds a four-week-old baby by inserting a thin tube into its stomach. Raising baby opossums — which differ from possums, an entirely different marsupial native to Australia — was not always her life. Nor has it been her most unusual vocation. As a young adult in Germany, Hinzen spent more than a decade judging skydiving competitions. Parachuters would hurl themselves from planes, sometimes do tricks in the air, and then try to land on a target. (She, herself, has jumped from a plane close to 500 times.) From there, Hinzen pursued a career in viticulture, got married, and built a wine importing company in NYC with her then-husband. Years later — now more than a decade ago — Hinzen’s marriage and her company fell apart, she told me, as we shared a bottle of wine on a bench in Central Park. Her world crumbled. It was around that time, Hinzen says, that she came across an injured pigeon in the Upper West Side. The bird was puffed up on the steps of a church and looked emaciated. Hinzen felt an urge to help. “It seemed like she had already checked out and given up on life,” Hinzen told me. “I think that’s what drew my attention, because I felt almost the same.” Hinzen prepares a baby opossum for feeding. She uses a specialized animal infant formula. At this age, Hinzen feeds the baby opossums five times a day. Each feeding takes about an hour and a half, she told me. Hinzen brought home the debilitated bird and with help from a local rehab center, nursed it back to health. She released the pigeon — Richard — a few months later. “To see that you can bring something back from the edge of death that has lost all hope ignited my passion,” she told me. Hinzen, a Buddhist, rescued more pigeons in the months that followed, eventually graduating to infant squirrels and opossums. They have become her specialty. In the spring, Hinzen told me that she might have 40 babies at one time and be tending to them 18 or 19 hours a day. “It has completely taken over my life,” she says. In these creatures, Hinzen, like other rehabbers, sees something that many of us don’t: something relatable. “I’m absolutely convinced that these animals have an emotional life,” she says. “At the end of the day, all they want is to live, to bring up their families, and to eat. They want the same as we want.” “At the end of the day, all they want is to live. They want the same as we want.” Feeling a connection with these animals, and compassion for them, has enriched her life in the city, she says. Even just noticing them more — their quirky behaviors, their bizarre features — can inspire awe, she says. “We are conditioned to see ourselves as different from other living beings,” Hinzen told me. “We have lost a feeling of connection to them. We have forgotten that we are part of nature and part of an ecosystem as much as they are.” Amanda Lullo, a rehabber in Staten Island, prepares to feed a handful of orphaned baby squirrels. Amanda Lullo, a squirrel rehabber on Staten Island, echoes some of that thinking. “Everything serves a purpose,” she told me. Rats are “nature’s garbage disposals,” she says, and squirrels are “nature’s gardeners,” since they bury seeds that grow into trees — at least when they don’t retrieve them to eat later. “We need these animals,” she says. I visited Lullo’s home on two separate occasions this spring. It’s a modest duplex that looks pretty ordinary. Until you walk inside. About two dozen cages, filled with squirrels, rats, and a couple of ferrets, were stacked up against the walls. An IV hung from the ceiling. A handful of pet cats and a rescued pit bull roamed around — and, in one case, slept on top of — the cages, remarkably disinterested in the animals inside. As we walked around her home, Lullo, who grew up in Brooklyn, introduced me to the animals. There was Pistachio, a.k.a. Fat Boy, a pudgy squirrel who fell from a tree as a baby. The fall broke his arm and cracked his tooth, she said, as the animal (now mostly healed) crawled around Lullo’s body. Lullo also showed me several baby squirrels including a five-week-old; she feeds them a special animal infant formula with a dash of heavy cream using a syringe. Lullo feeds a blueberry to one of the young squirrels she’s caring for. An array of clean syringes that Lullo uses to feed the baby squirrels. I also met a couple of wild rats, most named after fruits, including Strawberry and Blueberry. (Lullo raised them from infancy. Sometimes when people kill rats they find out that they have babies, Lullo said. They feel bad and call a rehabber.) Though common, these animals are deserving of care, Lullo says. “Humans kill and destroy everything they touch,” she says. The animals of New York City, she explains, are mostly harmless and they just want to live. Once rehabbers start caring for injured wildlife, they also just find it hard to stop. These people see critters in need everywhere. Rehabber Mary Beth Artz throws food pellets into a lake in Brooklyn’s Prospect Park to try and attract a domestic duck in need of rescue. “Once you know, you can’t unknow,” said Mary Beth Artz, a rehabber and stage actor who rescues ducks and other birds from Prospect Park in Brooklyn. (She’s currently rehabbing a jumbo Pekin named Freddie at her home. Last fall, the duck, which may have been purchased as a pet, was abandoned in a Queens parking lot, she said.) “I say it all the time — ‘I’m not going to do this anymore’ — but then something else happens,” Artz told me one afternoon in Prospect Park, while she was trying to rescue a domestic khaki Campbell duck that was dumped in the lake. “If we don’t do it, who’s going to do it?” An uncomfortable answer to that question might be, well, perhaps no one should. Indeed, there are some good reasons to limit the numbers of certain urban critters. Raccoons and skunks can carry rabies and other diseases. Rodent infestations, meanwhile, are particularly harmful to people experiencing homelessness, Brookshire writes in Pests. Their constant squeaks can make it impossible to sleep. (I couldn’t find anyone, aside from Lullo, who is rehabbing rats in the city. Lullo doesn’t plan to release them. Similarly, rehabbers seldom rescue raccoons, which require a more advanced license.) “Disease is always a risk with wildlife,” said Myles Davis, a city wildlife expert who manages NYC Audubon’s green infrastructure program. (That said, “You are never at risk of getting rabies from a raccoon,” he added, if you only observe it from afar.) A red-tailed hawk in Green-Wood Cemetery rips apart a pigeon, an abundant food source in NYC. An overabundance of these animals can also interfere with efforts to protect the city’s rarer species — stoking longstanding tensions between animal welfare and conservation. Pigeons may be an important food source for native raptors, including the once near-extinct peregrine falcon, but raccoons and opossums eat the eggs and chicks of native birds, according to Partridge. This complicates the question of what belongs in an urbanized environment. I raised these tensions with Catherine Quayle, a spokesperson for the Wild Bird Fund, the city’s most well-known and largest rehab center, mostly focused on birds. “Wildlife rehab is not a practice of conservation,” she told me. “It’s a practice of compassion.” To tell the public that some animals matter and other ones don’t “defeats our mission,” she said, “which is to teach people about wildlife.” As Quayle sees it, showing compassion for any wild creature, whether it’s a pigeon pecking at a slice of pizza or a songbird flying through during spring migration, can engender more respect for the wild world at large. It can help erode the dividing line between humans and pests, ultimately making us better stewards of our environment. We really need to be better stewards. Many features of the NYC built environment harm all animals, rare and common alike. Building windows are too reflective, causing birds to crash into them. Rat poison not only makes rodents suffer but harms the rodent-eating raptors. Flaco, a famous owl that escaped last year from the Central Park Zoo (with the help of a miscreant), died recently after colliding with a building. An autopsy revealed that he had four kinds of rat poison in his body (as well as a form of herpes found in pigeons). This doesn’t mean we should throw up our hands and welcome these animals in with open arms. But maybe — just maybe — NYC could find a way to, you know, not place trash on the street in flimsy plastic bags. (The city says it’s working on it.) You may think urban animals are gross, but we are the ones filling the city with trash. After warm weekend days, trash cans in Prospect Park are overflowing with animal-attracting garbage. Two of NYC’s most common (and most reviled) wild creatures. I still struggle with my own feelings toward these creatures. I happen to live on a rat-ridden street in Brooklyn. On a walk the other night, my dog lunged for a stray cat which then lunged for a large rat (and successfully snatched it). I’ve dealt with mice and bugs in my apartment. Last fall, I had to move because of a roach infestation. If this is the New York City ecosystem, I’m not sure how close to nature I want to be. What is clear to me is the simple power of connecting with animals as individuals, of pausing even briefly to observe their lives. Watching house sparrows bathe in a grimy fountain or squirrels chase each other around a tree can, I’d argue, inspire awe. And to see them suffering can be incredibly painful. That much was clear to me back in Bay Ridge, where I was waiting with Martin, the bird rehabber, for the pigeon delivery. A white SUV pulled up, and the driver retrieved a cat carrier from the backseat. Martin took the carrier and set it down on a nearby bench. The pigeon inside was still and its eyes glossy; I could see its breast faintly rise and fall. It wasn’t doing well, Martin said. The bird was about to die. We sat there in silence, Martin lightly petting the pigeon’s back. And a moment later, the animal was completely still. It had passed away, Martin told me. “You never get used to it,” she said, quietly. Frankly, I was devastated. I’ve rarely given pigeons much thought, but at that moment — after witnessing life vanish — I was comforted knowing that these birds, and that so many other unloved creatures across the city, have people looking out for them.

In NYC, many wildlife rehabbers see pests as part of a thriving urban ecosystem.

BAY RIDGE, New York City — One sunny afternoon in March, Amina Martin answered the phone in her small Brooklyn apartment. On the line was a taxi driver, who told her he had a pigeon in his backseat and was heading her way. The bird needed Martin’s help.

In New York, you never really know who your neighbors are. You might worry they have bedbugs or hoard cats. Maybe they’re celebrities. Or perhaps their apartments are filled with opossums, squirrels, and birds, all rescued from the streets of NYC.

Martin, a Russian immigrant, is that neighbor.

Her studio is full of pigeons, morning doves, and a handful of other stray birds including an African gray parrot named Elmoar. The animals are in cages that line the wall in front of her bed. Some of the birds have broken wings, trouble walking, or are partially blind. Others are abandoned pets with little chance of survival in the wild.

At least twice a week, Martin lets each pigeon out of its cage to fly around her apartment.

It was loud in her apartment when I met her that afternoon — a racket of coos and cheeps and the occasional interjection from Elmoar. “He’s teaching me English,” Martin jokes, adding that he says words like “whatsoever” that she’s had to look up.

Martin let out a couple of pigeons who flew around her apartment, including her favorite bird, named Anfisa. The animal had ombré gray plumage with pops of iridescent purple and green (i.e., she looked like a pigeon). “She’s in love with my husband,” Martin told me. “She lays eggs on his pillow because she thinks he’s her boyfriend.”

Martin is among a small number of people across the New York City boroughs who rehabilitate injured creatures that many other people label as pests. The driver who called Martin had brought birds to her before; an acquaintance of hers finds injured pigeons on the street and calls the same one or two taxi drivers to deliver them. (Sending birds via taxi? “It’s a common thing,” Martin says.)

Over several weeks this spring, I met more than a dozen licensed wildlife rehabilitators (aka, “rehabbers”) in New York. Many of them, like Martin, care for animals at home, turning their living rooms into makeshift wildlife hospitals. I visited a duplex in Staten Island full of squirrels and rats; a room in the Upper West Side with a box of baby opossums; and a small park on Roosevelt Island with injured Canada geese, adult opossums, and house cats, all living together and in some cases sleeping side-by-side. One rehabber in Manhattan told me she converted her balcony into an atrium for injured birds.

New York’s rehabber community is small; the opossum, pigeon, and squirrel people tend to know each other. Some of them, like Martin, document their work on Instagram, amassing a hefty following. But many of them operate under the radar to avoid unwanted attention from the Department of Health, or their landlords. (A bedroom full of squirrels is typically beyond a building’s pet policy.)

You might be thinking: What are they thinking? People are commonly disgusted by the animals that have adapted to live alongside us — to eat our garbage, to sleep in our streets. We typically want them out of our homes, not in. Wild animals, no matter the species, can also be noisy, dirty, and sometimes diseased. (One of Martin’s pigeons pooped on her bed, and of course, I sat right in it.)

What’s even more puzzling is that most of these rehabbers work for free, often around the clock, to care for these animals until they’ve healed. They often spend what little money they have on feed, specialized equipment including syringes and IV bags, and medicine. One rehabber told me that she can’t afford to buy herself new clothes. “I’m so broke right now,” they said. “All of my money goes to the animals.”

As I spent time with rehabbers, I began to see their perspective. They view these species not as pests but as part of nature — as part of the New York City ecosystem. As part of their home. These animals belong here, rehabbers told me, just as much as we do. And they don’t deserve the harm that humans so often inflict on them, whether deliberately or not.

By showing these animals some respect and helping them survive, rehabbers appear to feel more connected with their environment, with what they see as nature. That enriches their lives and makes them feel less alone.

Maybe they’re onto something.

Nearly every inch of New York, the nation’s largest and densest city, has been transformed by humans. Even its parks are largely artificial: The ponds, streams, and waterfalls in Manhattan’s Central Park, for example, are fed by city drinking water.

Yet the city is brimming with non-human life.

On a warm evening in March, I strolled through Central Park and saw a few dozen raccoons, several of which were eating a large pile of spaghetti. I put a motion-sensing camera in Brooklyn’s Green-Wood Cemetery (where conductor and pianist Leonard Bernstein, among other icons, is buried) and it captured videos of groundhogs, skunks, opossums, and stray cats. The city’s ponds are full of turtles. There are even seahorses in the Hudson River, once a dumping ground for chemicals and dead bodies.

“I see nature everywhere in New York City,” says Dustin Partridge, director of conservation and science at NYC Audubon, one of the leading environmental groups in the city.

Some of the city’s animals are native to the region and have found ways to survive, even as developers chop up and pave over their habitats.

These days they’re happy to nest on the sides of buildings. Of the several million tons of trash the city produces each year, the occasional overflowing receptacle or torn trash bag provides ample food for rats and raccoons.

The plight of these common city animals is that they are so widely unloved. We treat them as if they don’t belong here, in our home. Even if they’re native to New York, we don’t want them in our city. Cities are for humans. Distant forests — environments that we can visit at our leisure, on our own terms — are for them.

In these creatures, Hinzen, like other rehabbers, sees something that many of us don’t: something relatable. “I’m absolutely convinced that these animals have an emotional life,” she says. “At the end of the day, all they want is to live, to bring up their families, and to eat. They want the same as we want.”

Feeling a connection with these animals, and compassion for them, has enriched her life in the city, she says. Even just noticing them more — their quirky behaviors, their bizarre features — can inspire awe, she says.

“We are conditioned to see ourselves as different from other living beings,” Hinzen told me. “We have lost a feeling of connection to them. We have forgotten that we are part of nature and part of an ecosystem as much as they are.”

Amanda Lullo, a squirrel rehabber on Staten Island, echoes some of that thinking. “Everything serves a purpose,” she told me. Rats are “nature’s garbage disposals,” she says, and squirrels are “nature’s gardeners,” since they bury seeds that grow into trees — at least when they don’t retrieve them to eat later. “We need these animals,” she says.

I visited Lullo’s home on two separate occasions this spring. It’s a modest duplex that looks pretty ordinary. Until you walk inside. About two dozen cages, filled with squirrels, rats, and a couple of ferrets, were stacked up against the walls. An IV hung from the ceiling. A handful of pet cats and a rescued pit bull roamed around — and, in one case, slept on top of — the cages, remarkably disinterested in the animals inside.

As we walked around her home, Lullo, who grew up in Brooklyn, introduced me to the animals. There was Pistachio, a.k.a. Fat Boy, a pudgy squirrel who fell from a tree as a baby. The fall broke his arm and cracked his tooth, she said, as the animal (now mostly healed) crawled around Lullo’s body. Lullo also showed me several baby squirrels including a five-week-old; she feeds them a special animal infant formula with a dash of heavy cream using a syringe.

I also met a couple of wild rats, most named after fruits, including Strawberry and Blueberry. (Lullo raised them from infancy. Sometimes when people kill rats they find out that they have babies, Lullo said. They feel bad and call a rehabber.)

Though common, these animals are deserving of care, Lullo says. “Humans kill and destroy everything they touch,” she says. The animals of New York City, she explains, are mostly harmless and they just want to live.

Once rehabbers start caring for injured wildlife, they also just find it hard to stop. These people see critters in need everywhere.

Rehabber Mary Beth Artz throws food pellets into a lake in Brooklyn’s Prospect Park to try and attract a domestic duck in need of rescue.

“Once you know, you can’t unknow,” said Mary Beth Artz, a rehabber and stage actor who rescues ducks and other birds from Prospect Park in Brooklyn. (She’s currently rehabbing a jumbo Pekin named Freddie at her home. Last fall, the duck, which may have been purchased as a pet, was abandoned in a Queens parking lot, she said.)

“I say it all the time — ‘I’m not going to do this anymore’ — but then something else happens,” Artz told me one afternoon in Prospect Park, while she was trying to rescue a domestic khaki Campbell duck that was dumped in the lake.

“If we don’t do it, who’s going to do it?”


An uncomfortable answer to that question might be, well, perhaps no one should. Indeed, there are some good reasons to limit the numbers of certain urban critters.

Raccoons and skunks can carry rabies and other diseases. Rodent infestations, meanwhile, are particularly harmful to people experiencing homelessness, Brookshire writes in Pests. Their constant squeaks can make it impossible to sleep. (I couldn’t find anyone, aside from Lullo, who is rehabbing rats in the city. Lullo doesn’t plan to release them. Similarly, rehabbers seldom rescue raccoons, which require a more advanced license.)

“Disease is always a risk with wildlife,” said Myles Davis, a city wildlife expert who manages NYC Audubon’s green infrastructure program. (That said, “You are never at risk of getting rabies from a raccoon,” he added, if you only observe it from afar.)

A hawk perched in a tangle of branches in a tree eats from a dead pigeon held in its talons.
A red-tailed hawk in Green-Wood Cemetery rips apart a pigeon, an abundant food source in NYC.

An overabundance of these animals can also interfere with efforts to protect the city’s rarer species — stoking longstanding tensions between animal welfare and conservation. Pigeons may be an important food source for native raptors, including the once near-extinct peregrine falcon, but raccoons and opossums eat the eggs and chicks of native birds, according to Partridge. This complicates the question of what belongs in an urbanized environment.

I raised these tensions with Catherine Quayle, a spokesperson for the Wild Bird Fund, the city’s most well-known and largest rehab center, mostly focused on birds. “Wildlife rehab is not a practice of conservation,” she told me. “It’s a practice of compassion.” To tell the public that some animals matter and other ones don’t “defeats our mission,” she said, “which is to teach people about wildlife.”

As Quayle sees it, showing compassion for any wild creature, whether it’s a pigeon pecking at a slice of pizza or a songbird flying through during spring migration, can engender more respect for the wild world at large. It can help erode the dividing line between humans and pests, ultimately making us better stewards of our environment.

We really need to be better stewards. Many features of the NYC built environment harm all animals, rare and common alike. Building windows are too reflective, causing birds to crash into them. Rat poison not only makes rodents suffer but harms the rodent-eating raptors. Flaco, a famous owl that escaped last year from the Central Park Zoo (with the help of a miscreant), died recently after colliding with a building. An autopsy revealed that he had four kinds of rat poison in his body (as well as a form of herpes found in pigeons).

This doesn’t mean we should throw up our hands and welcome these animals in with open arms. But maybe — just maybe — NYC could find a way to, you know, not place trash on the street in flimsy plastic bags. (The city says it’s working on it.) You may think urban animals are gross, but we are the ones filling the city with trash.

After warm weekend days, trash cans in Prospect Park are overflowing with animal-attracting garbage.

Two of NYC’s most common (and most reviled) wild creatures.

I still struggle with my own feelings toward these creatures. I happen to live on a rat-ridden street in Brooklyn. On a walk the other night, my dog lunged for a stray cat which then lunged for a large rat (and successfully snatched it). I’ve dealt with mice and bugs in my apartment. Last fall, I had to move because of a roach infestation. If this is the New York City ecosystem, I’m not sure how close to nature I want to be.

What is clear to me is the simple power of connecting with animals as individuals, of pausing even briefly to observe their lives. Watching house sparrows bathe in a grimy fountain or squirrels chase each other around a tree can, I’d argue, inspire awe. And to see them suffering can be incredibly painful.

That much was clear to me back in Bay Ridge, where I was waiting with Martin, the bird rehabber, for the pigeon delivery. A white SUV pulled up, and the driver retrieved a cat carrier from the backseat. Martin took the carrier and set it down on a nearby bench.

The pigeon inside was still and its eyes glossy; I could see its breast faintly rise and fall. It wasn’t doing well, Martin said. The bird was about to die. We sat there in silence, Martin lightly petting the pigeon’s back. And a moment later, the animal was completely still. It had passed away, Martin told me.

“You never get used to it,” she said, quietly.

Frankly, I was devastated. I’ve rarely given pigeons much thought, but at that moment — after witnessing life vanish — I was comforted knowing that these birds, and that so many other unloved creatures across the city, have people looking out for them.

How the new wildlife crossing over I-5 will help delicate Oregon ecosystem

The new crossing will be in southern Oregon in the Siskiyous, where the freeway bisects the home of an impressive list of flora and fauna

The terrain south of Ashland and stretching to the California border sits at an incredible intersection of ecological systems.Here, the ancient Siskiyou Mountains meet the volcanic Cascades, the high desert of the Great Basin, the Klamath Mountains and the oak woodlands of Northern California.Dubbed an “ecological wonderland” and home to an impressive list of flora and fauna, the area was designated as the Cascade-Siskiyou National Monument in 2000.Plowing through all that biodiversity is Interstate 5, which carries 17,000 vehicles per day. The four-lane interstate essentially severs the monument into two.Animals don’t have an easy time getting from one side of the road to the other. Due to its location, however, the area is a hotbed of wildlife activity and considered a “red zone” for vehicle collisions.“The traffic volume on most portions of I-5 would be considered to be a permanent barrier to wildlife movement,” Tim Greseth, executive director of the Oregon Wildlife Foundation, tells Columbia Insight. “The oddity with this particular location is it’s smack dab in the middle of the Cascade-Siskiyou National Monument, which was established primarily because of the biodiversity of the region.”Now there’s good news, for wildlife and motorists alike.Artist's rendering of Oregon's first overcrossing for wildlife, proposed for just north of the California border.ODOTThe area will soon get a lot safer thanks to a $33 million federal grant to the Oregon Department of Transportation to construct a massive wildlife crossing over I-5 just north of the Oregon-California border.“The grant award will allow ODOT to construct a wildlife crossing over Interstate 5 in southern Oregon in the Cascade-Siskiyou National Monument,” according to the ODOT website. “This will be the first wildlife overcrossing for Oregon and for the entire stretch of I-5 between Mexico and Canada.”Announced in December, the grant award for the Southern Oregon Wildlife Overcrossing is the result of years of work and collaboration spearheaded by the Southern Oregon Wildlife Crossing Coalition, which formed in 2021 to push for animal crossings in the monument.ODOT will provide another $3.8 million in matching funds that will come from a pot of money created by the 2021 Oregon Legislature to support wildlife crossings across the state.Construction is expected to begin in 2028, according to ODOT.Overcross vs. undercrossEach year in Oregon, officials document about 6,000 vehicle collisions with deer and elk.Wildlife crossings are effective at reducing such collisions.Oregon’s six existing wildlife undercrossings—tunnels constructed beneath roads—have resulted in an 80-90% decrease in vehicle-wildlife collisions in impacted areas, according to ODOT and the Oregon Department of Fish and Wildlife.“There’s a real advantage to doing overcrossings versus undercrossings,” says Greseth. “Overcrossings get a lot more diversity of species use. If you think about an underpass—and think about even people and how we might approach something where we’re going underneath a busy road—each of us individually would probably approach that with some trepidation. Animals aren’t going to be different.”The proposed I-5 overcross will consist of soil, vegetation and landscaping elements to make the crossing feel safer to wildlife. It will include retaining walls and sound walls along its length to dampen interstate noise and shield wildlife from light on the road.Dense plantings of vegetation will offer cover from predators for smaller animals, while open paths along the crossing will give animals using the bridge the ability to see their destination, according to ODOT spokesperson Julie Denney.ODOT’s landscape architect and a multidisciplinary subgroup are planning which plants to use on the bridge. The team is “focusing on the plants that will help make the crossing the most attractive for the species we expect to utilize the crossing,” says Denney. Those species include deer, elk, bear, cougar, birds and even insects.Potential plants for the crossing include sugar pine, desert gooseberry, deer brush, Oregon white oak, dwarf Oregon white oak, rubber rabbitbrush, antelope bitterbrush and spreading dogbane.The structure will span northbound and southbound lanes, and have fencing stretching two-and-a-half miles in each direction and on either side of the interstate. The fencing will help funnel wildlife onto the bridge.“Our goal is to provide an environment for the crossing to be as natural as possible, hopefully in a way that the wildlife are unaware they are crossing a major interstate,” says Denney.Kendra Chamberlain is Columbia Insight’s contributing editor.

Although Costa Rica is committed to protecting wildlife, unscrupulous individuals continue to violate the rules and insist on keeping wild animals as pets. The National System of Conservation Areas (SINAC) rescued a white-faced monkey that was held in captivity in Jacó. The animal was tied with a chain around its neck, which caused serious injuries, according to SINAC personnel. “He no longer had any hair to protect him around the neck because of the chain. He had open wounds that must have caused him a lot of pain,” officials stated. The animal was taken to Zooave, located in La Garita de Alajuela, where it is receiving veterinary medical attention. SINAC emphasized that keeping wildlife in captivity is a crime and urges people to report any cases they know of. “For those who had this animal in captivity, the corresponding complaint was filed with the Public Prosecutor’s Office,” SINAC confirmed. Parrots, parakeets, turtles, snakes, and iguanas are among the wild animals protected by the Wildlife Conservation Law in Costa Rica.   On the other hand, a two-toed sloth cub was rescued in the canton of Upala during an operation involving the Public Force, local residents, and SINAC. The rescue occurred after the officers received information about the female sloth cub, which had been found abandoned by a local family. According to authorities, the animal was handed over to the officers, who, while feeding and caring for her, began searching for the mother in the vicinity. Despite their efforts to locate her, it was not possible. On Wednesday, they coordinated with the wildlife rescue center “Toucan Rescue Ranch” in Río Frío, Sarapiquí, to transfer the calf, where it is receiving the proper care. “The two-toed sloth is a species facing a population decline in Costa Rica, mainly due to the destruction of its natural habitat and illegal capture for keeping as pets,” environmental authorities highlighted. Keeping animals in captivity is a crime in Costa Rica, which carries monetary penalties and even a prison sentence.

Fears of ‘rogue rewilding’ in Scottish Highlands after further lynx sightings

Environmentalists condemn unauthorised releases as ‘reckless’ and ‘highly irresponsible’For a brief moment this week, lynx have been roaming the Scottish Highlands once again.

For a brief moment this week, lynx roamed the Scottish Highlands once again. But this was not the way conservationists had hoped to end their 1,000-year absence.On Wednesday, Police Scotland received reports of two lynx in a forest in the Cairngorms national park, sparking a frantic search. That episode ended in less than a day. Both animals were quickly captured by experts from the Royal Zoological Society of Scotland (RZSS) and taken to quarantine facilities at Highland wildlife park.Yet their delight at a successful operation was shortlived. Early on Friday morning, the RZSS’s network of wildlife cameras caught two more lynx in the same stretch of forest, near Kingussie. The baited traps were redeployed, and its specialists were hunting again.Screen grab taken from video issued by the Royal Zoological Society of Scotland (RZSS) of one of the two Lynx captured in the Cairngorms on Thursday. Photograph: Royal Zoological Society of Scotland/PASpeculation has erupted over who was responsible for the illegal release, and police said enquiries were continuing to establish the full circumstances. Both lynx – who are shy, solitary animals in the wild and not dangerous to humans – appeared tame and showed little sign of being able to survive on their own, according to a witness. The witness said the lynx were found near straw bedding left beside a layby with dead chicks and porcupine quills.On social media, some pointed the finger at rogue rewilders taking the law into their own hands by making the return of lynx a fact on the ground, akin to how beavers returned to the UK through unauthorised “beaver bombing” . Studies indicate that the Highlands could support as many as 400 lynx in the wild and there is strong support for their return among environmental groups. But leading voices in the rewilding sector were quick to condemn this week’s unauthorised release as “reckless” and “highly irresponsible”.Dave Barclay, the RZSS expert leading the hunt for the lynx, was furious. These animals were semi-tame, and “highly habituated to people”, he said, yet had been released in deep winter. Temperatures locally had plunged below -5C, with deep snow cover, and they had been released at the mouth of a forest track heavily used by logging machinery.“All of that compromises the welfare of these animals,” he said. “It is abhorrent what has happened here, and against all international good practice.”Investigators now suspect the lynx could be from a family group. The two captured yesterday are understood to be juveniles, cubs aged about 1 or 2 years of age, while the two spotted on Friday are thought to be an adult and a third juvenile.Ben Goldsmith, an environmentalist who said he was not involved with the release, said: “Like many others, I have been momentarily thrilled by the notion of lynx once again stalking the Cairngorms. Lynx are an iconic native species missing from Britain and they should be back here. The habitat is perfect, these are secretive animals, and there are no good reasons not to reintroduce them.“We don’t know the story behind these missing lynx – perhaps they are abandoned pets that have become unmanageable. Whatever has happened, it seems to have been poorly thought through,” he added.The lynx were found on Danish billionaire Anders Povlsen’s Killiehuntly estate. A spokesperson for WildLand, the company that runs his Scottish estates, said they believed that native predators should only be reintroduced lawfully and in close collaboration with local people.In the UK, citizens must apply to their local council to keep wild animals legally. According to figures collected by Born Free in 2023, 31 lynx were kept by private collectors, although all were housed in England. Experts said that more lynx were likely to be held in unauthorised private collections that were difficult to monitor.“There could be far more lynx in private hands that are actually recorded. If they have cubs, they may not register them. People would be gobsmacked of what people have in their back garden. I know of people who have snow leopards and cougars in their back garden. It’s shocking. It should be banned,” said Dr Paul O’Donoghue, director of the Lynx UK Trust, who also said he was not involved with therelease.Were it not for the English Channel, lynx would probably already have returned to the UK. Now a protected species in Europe, the Eurasian lynx has recovered from a few hundred in the 1950s to as many as 10,000. Research shows there is mixed support for their return in the UK, with strong opposition from the agricultural community, who fear they will attack livestock.Edward Mountain, MSP for the Highlands and Islands and a landowner, said there was a “genuine fear” amongst locals about “guerrilla rewilding”. “We saw it with beavers on the Tay, now there’s talk of reintroducing sea eagles and goshawks. It can change an entire local ecosystem and that’s dangerous if it’s not done properly,” he said.

Why sabre-toothed animals evolved again and again

Sabre teeth can be ideal for puncturing the flesh of prey, which may explain why they evolved in different groups of mammals at least five times

The skull of a saber-toothed tiger (Smilodon)Steve Morton Predators have evolved sabre teeth many times during the history of life – and we now have a better idea why these teeth develop as they do. Sabre teeth have very specific characteristics: they are exceptionally long, sharp canines that tend to be slightly flattened and curved, rather than rounded. Such teeth have independently evolved in different groups of mammals at least five times, and fossils of sabre-tooth predators have been found in North and South America, Europe and Asia. The teeth are first known to have appeared some 270 million years ago, in mammal-like reptiles called gorgonopsids. Another example is Thylacosmilus, which died out about 2.5 million years ago and was most closely related to marsupials. Sabre teeth were last seen in Smilodon, often called sabre-toothed tigers, which existed until about 10,000 years ago. To investigate why these teeth kept re-evolving, Tahlia Pollock at the University of Bristol, UK, and her colleagues looked at the canines of 95 carnivorous mammal species, including 25 sabre-toothed ones. First, the researchers measured the shapes of the teeth to categorise and model them. Then they 3D-printed smaller versions of each tooth in metal and tested their performance in puncture tests, in which the teeth were mechanically pushed into gelatine blocks designed to mimic the density of animal tissue. This showed that the sabre teeth were able to puncture the block with up to 50 per cent less force than the other teeth could, says Pollock. The researchers then assessed the tooth shape and puncture performance data using a measure called the Pareto rank ratio, which judged how optimal the teeth were for strength or puncturing. “A carnivore’s teeth have to be sharp and slender enough to allow the animal to pierce the flesh of their prey, but they also need to be blunt and robust enough to not break while an animal’s biting,” says Pollock. Animals like Smilodon had extremely long sabre teeth. “These teeth were probably popping up again and again because they represent an optimal design for puncture,” says Pollock. “They’re really good at puncturing, but that also means that they’re a little bit fragile.” For instance, the La Brea Tar Pits in California have lots of fossils of Smilodon, some with broken teeth. Other sabre-toothed animals also had teeth that were the ideal shape for a slightly different job. The cat Dinofelis had squatter sabre teeth that balanced puncturing and strength more equally, says Pollock. The teeth of other sabre-toothed species sat between these optimal shapes, which might be why some of them didn’t last too long. “These kinds of things trade off,” says Pollock. “The aspects of shape that make a tooth good at one thing make it bad at the other.” One of the main hypotheses for why sabre-tooth species went extinct is that ecosystems were changing and the huge prey they are thought to have targeted, such as mammoths, were disappearing. The team’s puncture findings back this up. The giant teeth wouldn’t have been as effective for catching prey that were more like the size of a rabbit, and the risk of tooth breakage here may have increased, so the sabre-toothed animals would have been outcompeted by predators that are more effective at hunting such prey, like cats with smaller teeth, says Pollock. “As soon as the ecological or environmental conditions change, the highly specialised sabre-tooth predators were unable to adapt quickly enough and became extinct,” says Stephan Lautenschlager at the University of Birmingham, UK. “I think that’s part of the reason why this sabre-tooth morphology hasn’t evolved again in the present – we don’t have the megafauna,” says Julie Meachen at Des Moines University in Iowa. “The prey is not there.”

Oregon approves key permit for controversial biofuel refinery on Columbia River

Oregon environmental regulators gave a key stamp of approval to a proposed $2.5 billion biofuel refinery along the Columbia River despite continued opposition from environmental groups and tribes over potential impacts to the river and salmon.

Oregon environmental regulators gave a key stamp of approval to a proposed $2.5 billion biofuel refinery along the Columbia River despite continued opposition from environmental groups and tribes over potential impacts to the river and salmon.The NEXT Energy refinery, also known as NXTClean Fuels, plans to manufacture renewable diesel and sustainable aviation fuel at the deepwater port of Port Westward, an industrial park on the outskirts of Clatskanie in Columbia County. Biofuels are considered renewable because they are produced from plants and organic waste products such as cow manure or agricultural residue.The Department of Environmental Quality on Tuesday approved a water quality certification for NEXT, allowing the Houston-based company to move forward with the project. The certification – marking the final comprehensive state review – is a requirement for the refinery to secure a federal permit from the U.S. Army Corps of Engineers.The state agency previously twice denied NEXT’s application for the certification, in 2021 and 2022, “due to insufficient information to evaluate the permit application.” More recently, the company secured state approvals for a removal fill permit and air permit in 2022 and county land-use permits in 2024.Proponents hail biofuels for their ability to reduce carbon emissions as a stop-gap measure before the transportation sector can move to full-on electrification as climate groups advocate. Countries across the world, including the U.S., individual states like Oregon and cities such as Portland have bet on biofuels to reduce carbon emissions from cars and trucks via fuel blending mandates that require a certain percentage of biofuels to be mixed with traditional fossil fuels.Environmental groups have raised concerns in recent years about the impacts of biofuel production, storage and transportation, including deforestation, the displacement of food production and the significant greenhouse gas emissions from various biofuel sources.The Port Westward refinery plans to produce up to 50,000 barrels per day – or more than 750 million gallons a year – of renewable diesel and sustainable aviation fuel. The fuels will be shipped offsite via pipelines, trucks and railcars to markets worldwide.Environmental groups this week said state regulators “caved in” to pressure from the building trades, putting the river and people’s well-being at risk from possible spills.DEQ spokesperson Michael Loch declined to directly comment on that statement.“DEQ carefully reviewed NEXT’s application for a 401 water quality certification and determined that the proposed project meets the state’s water quality standards,” Loch said.NEXT has said it plans to make the biofuels at Port Westward from used cooking oil, fish grease, animal tallows and seed oils. It already has an agreement with a Vietnamese company to import fish grease, company spokesperson Michael Hinrichs said. And it’s in discussions with other companies for used cooking oil and animal tallows from Japan, South Korea, Indonesia, Singapore, Brazil and Canada, he said.Conservation groups in Oregon dispute those promises, pointing to the company’s filings with the U.S. Securities and Exchange Commission.“NEXT’s documentation shows that the majority of its feedstocks will be from corn and soybean oil, which are purpose-grown feedstocks with a higher carbon footprint, and will be shipped to the facility on long trains,” said Audrey Leonard, a staff attorney with Columbia Riverkeeper, a Portland-based environmental group focused on protecting the river that has fought the project for years.Columbia Riverkeeper and other opponents of the project also argue the refinery could damage water quality in the Columbia and its tributaries, including several area sloughs, and degrade local wetlands in the event of spills from the refinery and its railyard caused by accidents or a major earthquake.The proposed refinery would be built on unstable soil behind dikes that are next to high-value farmland and salmon habitat, Leonard said. Renewable fuels are just as flammable as fossil fuels, she said.In addition, the proposed refinery would use large volumes of fracked gas, a fossil fuel, in the production of renewable fuels, resulting in significant greenhouse gas emissions, Leonard said. NEXT’s air permit allows over 1 million tons a year of greenhouse gas emissions from the fracked gas operations to produce the fuel at the refinery. For comparison, the average petroleum refinery emits 1.2 million tons per year and Intel’s two campuses are authorized to emit a combined 1.7 million tons of greenhouse gases per year.The region’s tribes also have sent letters opposing the refinery, saying it will degrade water quality and negatively affect juvenile salmon and other aquatic species.“This project is a massive step backwards from the years of effort to improve aquatic habitat,” wrote Aja K. DeCoteau, executive director with the Columbia River Inter-Tribal Fish Commission which manages fisheries for local tribes.Other groups have expressed support for the project and see it as a climate change solution that will reduce emissions and pollution.“On our way to a zero-emission future, we must do everything we can to reduce greenhouse gas emissions and toxic air pollution in the short term through strategies like rapidly expanding the use of renewable diesel and sustainable aviation fuel,” wrote Tim Miller, the director of Oregon Business for Climate, a nonprofit group focused on mobilizing industry support to advance climate policy in Oregon.Now that the refinery has the water certification in hand, the Army Corps of Engineers will issue a draft environmental impact statement for public review later this year and will evaluate whether to issue a federal water quality permit for the project.NEXT still must secure two state stormwater permits, though those are routine and typically filed after approval of the federal permit.The company is also developing a second biofuel refinery in Lakeview, 100 miles east of Klamath Falls, after acquiring an existing never-opened facility in 2023 from Red Rock Biofuels when that company went into foreclosure. The Lakeview plant will use wood waste from local forest thinning, logging and wildfire management activities to make renewable natural gas, known as RNG. The company has yet to announce when the plant will launch.— Gosia Wozniacka covers environmental justice, climate change, the clean energy transition and other environmental issues.
