Reporting for this story was supported by the Nova Institute for Health. In the decades since Congress passed the Clean Air Act in the early 1960s, air quality monitoring has become one of the EPA’s central tools to ensure the agency delivers on the promise to protect people from polluted air. The EPA, in partnership with state regulators, oversees a network of roughly 4,000 monitors across the country that measure the levels of six pollutants detrimental to human health, including ozone, sulfur dioxide, and particulate matter. But the network was primarily set up to track pollution from automobiles and industrial facilities such as coal-fired power plants near large population centers; as a result, the monitors are not evenly distributed across the United States. Of consequence, a 2020 analysis by the environmental group Natural Resources Defense Council found that more than 100 counties modeled to have unhealthy levels of particulate matter did not have an air quality monitor to track Clean Air Act compliance. And, research indicates that communities of color are often in closer proximity to industrial polluters and are disproportionately exposed to air pollution. Even the growing network of non-EPA, low-cost air quality sensors, such as PurpleAir, which are used to crowdsource real-time air quality data, are located predominantly in affluent White communities that can better afford them.  To better address these monitoring gaps, the EPA awarded $53 million in grants to 133 community groups in 2022. Earlier this year, many of these groups began setting up their own air quality monitors to identify pollution from a variety of sources including industrial operations, waste burning, and oil and gas development. The program is funded by the Inflation Reduction Act and the American Rescue Plan and was designed to invest in public health with a focus “on communities that are underserved, historically marginalized, and overburdened by pollution.” “One of the best things EPA can do is continue to work closely with communities and state and local air agencies to address air issues in and around environmental justice areas,” said Chet Wayland, director of the EPA’s air quality assessment division. “I’ve been at the agency for 33 years; this is the biggest shift in monitoring capabilities that I’ve seen because of all this technology.” But despite the funding, the groups that received EPA grants have no guarantee that their data will drive change. For one, some state lawmakers have passed legislation that blocks local regulators from utilizing monitoring data collected by community groups. While the EPA encouraged grantees to partner with regulatory bodies, they don’t require regulators to incorporate the data groups are collecting into their decision-making either. As a result, states could simply ignore the data. The program also places a burden on the very communities experiencing the country’s worst air quality who now have to figure out how to site, operate, and maintain monitors, tasks that require technical expertise.  Chemical plants in southeastern Louisiana emit dozens of pollutants that harm public health, but the state’s monitors do not adequately capture these emissions, community groups say. Giles Clarke / Getty Images Micah 6:8 was one of the dozens of community groups awarded an EPA grant to purchase an air quality monitor. The group was founded six years ago by Cynthia Robertson to serve the residents of Sulphur, Louisiana, located in southwest Louisiana’s sprawling petrochemical corridor. The low-income majority African-American community is exposed to toxic emissions from industrial polluters and is one of the state’s cancer hotspots, but, the Louisiana Department of Environmental Quality, or LDEQ, the state environmental agency, maintains just four air monitors in the region. None are positioned to detect levels of particulate matter from a cluster of nearby polluting plants. “We knew we needed air monitors,” said Robertson. Yet Robertson’s data from the EPA-funded monitor will almost certainly not lead to regulatory changes. In May, Louisiana’s Republican Governor Jeff Landry signed legislation prohibiting the use of community air monitoring data for regulatory or legal affairs. The chief defenders of the bill were representatives from the Louisiana Chemical Association, a trade group representing the petrochemical industry. (State lawmakers passed a similar bill championed by industry in the West Virginia House, but it died earlier this year without Senate consideration.) “I already know that my data won’t be heeded by LDEQ,” said Robertson. “In this state, it’s a pointless conversation [with regulators].”  LDEQ did not respond to a request for comment. The EPA declined to comment on the Louisiana law. “We strongly encouraged community groups to partner with a local or state agency that they could feed the data back to, but we recognize that this can vary across states,” said Wayland. Still, collecting air quality data, Robertson said, has value. The EPA grant requires community groups to share their data with stakeholders, including local governments and the public. And even if the regulators won’t acknowledge her data, Robertson wants data to inform her community about what they are being exposed to. She is working with researchers at Carnegie Mellon to build a community-friendly website that will explain the data visually. If her neighbors have accurate information, she hopes it will shape who they vote for.  “[Having this data] will enable us to make grassroots changes,” she said. “When you have an upwelling of protest and distress from communities, then things will start to change.” In Texas, Air Alliance Houston, a non-profit advocacy group, has been trying to get the state environmental agency to take its community-based monitoring data seriously with little success. Since 2018, the group has installed roughly 60 monitors to inform community members, identify advocacy opportunities to reduce pollution, and to provide evidence for the need for more regulatory monitoring. Air Alliance’s executive director, Jennifer Hadayia, said the Texas Commission on Environmental Quality, or TCEQ, disregarded their data when making permitting decisions for new industrial facilities. For example, she said, TCEQ relied on a particulate matter monitor in Galena Park, a suburb east of Houston, to renew a permit for a concrete batch plant in a neighborhood more than 15 miles away. It was “nowhere near the impact of the concrete batch plant,” she said.  In May, the group along with 11 other organizations including the Houston Department of Transportation, sent the TCEQ requests for changes to its proposed air monitoring plan for the state. The group highlighted the need for more air quality monitors in communities of color in Port Arthur, Beaumont, and north Houston. Data they collected near Houston’s Fifth Ward documented that the region’s air quality did not meet federal air quality standards for particulate matter on more than 240 days last year. In addition, the group noted the lack of independent monitors for ethylene oxide, a toxic chemical released by facilities that convert fracked gas into other chemical products, despite an increase in the number of these plants in Texas. (In addition to the six air pollutants monitored nationwide, the EPA and state environmental agencies also regulate 188 hazardous air pollutants emitted by industrial facilities. While 26 ambient air monitors exist around the country to detect these pollutants, none are located in Texas or Louisiana.)  Richard Richter, a spokesperson for TCEQ, said that while comments from Hadayia’s organization and others were “thoroughly reviewed, no changes were made to the draft 2024 plan based on the comments received.”  Richter noted that TCEQ has responded on multiple occasions to questions regarding externally-collected air monitoring data, despite having no dedicated resources to do so. But he did not share any evidence of taking action in response to community data when asked for examples. “In general, the TCEQ’s discussions with external parties about their air monitoring data will include topics such as data quality assurance, measurement accuracy, if the data can be evaluated from a health perspective (and if it can be evaluated, how to do so), and explanations about how community air monitoring data are often different from the monitoring data requirements for comparison to federal air quality standards,” he said in an emailed comment.  The agency’s attitude toward community air quality data could affect John Beard’s monitoring efforts. Beard is the founder of the Port Arthur Community Action Network, an environmental justice organization that has been advocating for better regulation of the petrochemical industry. He partnered with Micah 6:8 on a joint grant from the EPA and received one of two identical air quality monitors earlier this year. John Beard, an environmental justice activist, is setting up an air quality monitor in Port Arthur, Texas with EPA funding. Virginia Gewin Port Arthur is home to the largest refinery in the country, Motiva Enterprises, which produces 640,000 barrels of oil a day. Last year, a Grist investigation found TCEQ allows Motiva and other companies to release over a billion pounds of sulfur dioxide, hydrogen sulfide, cancer-causing benzene, and other pollutants. Only 8 percent of such “excess emission” incidents, which typically occur due to machinery malfunctions, hurricanes, or power outages, received any penalty.  Given its track record, Beard said he doesn’t trust TCEQ or believe they will utilize the data his organization collects to inform regulatory changes. “They have an obligation to protect us, and they aren’t doing a very good job of it,” he said. As the federal agency in charge of implementing and enforcing environmental laws, the EPA has considerable authority over local regulatory programs — but it cannot dictate where states place monitors. Funding community groups directly is the agency’s attempt to fill monitoring gaps, particularly in communities of color.  “EPA could have plowed a bunch of money into the state regulatory frameworks, and nothing would have changed,” said Matthew Tejada, senior vice president for environmental health at the Natural Resources Defense Council. He helped craft the EPA grant program when he was director of the agency’s office of environmental justice. Community science, on the other hand, can help democratize environmental health protection, he said. “It’s not going to be quick,” he added. “It’s not going to be painless.” And ultimately it depends on communities’ ability to produce compelling, accurate data. To help communities produce the best data possible, the EPA required grant recipients to draft quality assurance plans and obtain approval from the agency prior to data collection. These plans ensure that the data being collected is replicable. EPA also provided all grantees with free contractor support for the development and review of those plans and other technical questions.  Richard Peltier, an atmospheric chemist at the University of Massachusetts Amherst who also works with community groups, said laws barring the use of data are detrimental to communities engaged in scientific research and undermine the state’s responsibility to protect its residents. The community-based air monitors, which are often lower quality, may produce noisy data which has greater variability compared to more tightly-controlled regulatory monitors, said Peltier, but they will still help identify hot spots of pollution in areas where researchers have never looked before. “The real strength of these community grants is that we will get data coming from where the people are, not where the monitors are,” said Peltier. But it will require scientific capacity that some communities may struggle to access. Some groups found the requirements to assemble the expertise to site, run, and produce quality controlled, robust data, which must be shared online, too onerous. As a result of administrative or technological challenges, seven grantees didn’t move forward, according to the EPA. Lake County Environmental Works, an environmental advocacy organization in Lindenhurst, Illinois, that Peltier advised, was one such group. The funding would have supplied a monitor to track ethylene oxide, a carcinogenic chemical that is used to sterilize medical equipment and notoriously difficult to measure. Ultimately John Aldrin, an engineer and founder of Lake County Environmental Works, determined he couldn’t volunteer the time necessary to manage a $160,000 ethylene oxide monitor that would require a significant amount of maintenance to produce sound data. “I think community groups need technical support from the EPA,” said Aldrin.  As it stands, Peltier added, the EPA community air monitor approach seems like a “do-it-yourself approach to public health.” Darren Riley, co-founder of Just Air Solutions based in Detroit, Michigan, installs an air quality monitor. His organization is working with several EPA-funded groups to set up monitors. Courtesy of Darren Riley Tejada joined the Natural Resources Defense Council last fall to help use community science to “support more and more communities doing good science that drives toward rules that are more protective, permits that limit pollution in a meaningful way, and make sure enforcement happens.” He advised community groups to get scientists involved to properly site the air monitors and develop a robust quality assurance data plan. “EPA can and should do more” to help communities use their monitors to produce robust data, said Tejada, but they are constrained by limited funding, personnel, and statutory authority.  To meet the demand for scientific expertise, a cottage industry is developing to help community organizations use these monitors. Darren Riley, co-founder of Just Air Solutions based in Detroit, Michigan, is working with five different EPA community air monitor grantees around the country in addition to county and city officials. Riley said while it can be difficult to assemble the expertise in a community-based endeavor, he sees a resurgence of fight and energy and hopefulness that things are finally going to change. “EPA is sending a signal. People feel as though they are seen, which has helped morale,” he said. For communities, it’s a feeling of empowerment. “I hear the term ‘our data’,” he added.  And that, said Tejada, is the goal. “Community-based air quality monitors could finally deliver on the promise of the Clean Air Act,” he said.  Editor’s note: Natural Resources Defense Council is an advertiser with Grist.

Funding communities burdened by pollution to monitor air quality is the “do-it-yourself approach to public health," one researcher said.

Why the health risks from air pollution could be worse than we thought

A new study found elevated and previously overlooked health risks for communities living near industrial polluters.

Many people who live near heavy industry are routinely exposed to dozens of different pollutants, which can result in a multitude of health problems.Traditionally, environmental regulators have assessed the risks of chemical exposure on an individual basis. But that approach has led to underestimates of the total health risks faced by vulnerable populations, according to a new study.Now researchers at Johns Hopkins University have developed a new method for measuring the cumulative effects on human health of multiple toxic air pollutants. Their findings were published last week in Environmental Health Perspectives.Regulators typically measure community risk by looking at the primary health effects of individual chemicals, an approach that often fails to address their combined risks, said Keeve Nachman, the study’s senior author.Residents in disadvantaged communities are exposed to a toxic stew of chemicals daily, and they “don’t just breathe one at a time, [they] breathe all the chemicals in the air at once,” said Peter DeCarlo, another of the study’s authors.Follow Climate & environment“Very little has happened to protect these people. And one of the major reasons for that is that current approaches have not done a good job showing they’re in harm’s way,” Nachman said.“When we regulate chemicals, we pretend that we’re only exposed to one chemical at a time,” Nachman continued. “If we have each chemical and we only think about the most sensitive effect, but we ignore the fact that it could potentially cause all these other effects to different parts of the body, we are missing protecting people from the collective mixture of chemicals that act together.”Nachman, DeCarlo and their colleagues set out to more accurately account for the total burden of breathing multiple toxic air pollutants.The study assessed the risks faced by communities in southeastern Pennsylvania living near petrochemical facilities using a mobile laboratory to measure 32 hazardous air pollutants, including vinyl chloride, formaldehyde and benzene. The researchers developed real-time profiles of the pollution concentrations in the air and translated them into estimates of what people are actually breathing.Using these estimates and a database of the chemicals’ toxic effects on various organs, the researchers created projections of the long-term cumulative health impacts of the pollution.By looking past the immediate health effects of chemicals and measuring what happens as concentrations increase, negative health outcomes can be detected in other parts of the body, Nachman said.For example, while EPA risk assessments consider only the respiratory effects of formaldehyde, the study found potential health impacts in 10 other organ systems, including neurological, developmental and reproductive harms.The cumulative risk study appears at a fraught moment for environmental regulation. Although the Biden administration in November released a draft framework for monitoring the cumulative impact of chemical exposure, the Trump administration has announced plans to roll back dozens of Biden administration environmental rules and is considering shutting down the EPA’s Office of Research and Development.A spokesperson for the American Chemistry Council, an industry trade group, said in an email that the Johns Hopkins research “may provide some useful information” but that “further assessment, replication and validation will be needed” of the methods and substances assessed in the study.“ACC continues to support the development of scientifically robust data, methods and approaches to underpin cumulative risk assessments,” the spokesperson added.The EPA did not provide an immediate comment while it reviewed the study.Jen Duggan, the executive director of the Environmental Integrity Project, said communities often face higher health impacts than the EPA estimates due to their exposure to dangerous chemicals from multiple sources.“The authors of this paper powerfully demonstrate how EPA has repeatedly underestimated the true health risks for people living in the shadow of industrial polluters,” Duggan said.

Utah Bans Fluoride In Public Drinking Water

Republican Gov. Spencer Cox signed the legislation despite widespread opposition from dentists and national health organizations.

SALT LAKE CITY (AP) — Utah has become the first state to ban fluoride in public drinking water, despite widespread opposition from dentists and national health organizations.Republican Gov. Spencer Cox signed legislation late Thursday that bars cities and communities from deciding whether to add the mineral to their water systems.Fluoride strengthens teeth and reduces cavities by replacing minerals lost during normal wear and tear, according to the U.S. Centers for Disease Control and Prevention.Utah lawmakers who pushed for a ban said putting fluoride in water was too expensive. Cox, who grew up and raised his own children in a community without fluoridated water, compared it recently to being “medicated” by the government.The ban comes weeks after U.S. Health Secretary Robert F. Kennedy Jr., who has expressed skepticism about water fluoridation, was sworn into office.More than 200 million people in the U.S., or almost two-thirds of the population, receive fluoridated water through community water. The addition of low levels of fluoride to drinking water has long been considered one of the greatest public health achievements of the last century.But some cities across the country have gotten rid of fluoride from their water, and other municipalities are considering doing the same. A few months ago, a federal judge ordered the U.S. Environmental Protection Agency to regulate fluoride in drinking water because high levels could pose a risk to the intellectual development of children.We Don't Work For Billionaires.

Low-income families may not be able to afford regular dentist visits or the fluoride tablets some people buy as a supplement in cities without fluoridation.The sponsor of the Utah legislation, Republican Rep. Stephanie Gricius, acknowledged fluoride has benefits, but said it was an issue of “individual choice” to not have it in the water.

Dozens of House Democrats push back on planned EPA research and development cuts

Dozens of House Democrats pushed back on planned Environmental Protection Agency (EPA) cuts in a Thursday letter to the agency. “We are particularly concerned by the proposal to eliminate up to 75 percent of employees within EPA’s Office of Research and Development (ORD),” the letter, from Rep. Greg Landsman (D-Ohio) and addressed to EPA Administrator...

Dozens of House Democrats pushed back on planned Environmental Protection Agency (EPA) cuts in a Thursday letter to the agency. “We are particularly concerned by the proposal to eliminate up to 75 percent of employees within EPA’s Office of Research and Development (ORD),” the letter, from Rep. Greg Landsman (D-Ohio) and addressed to EPA Administrator Lee Zeldin, reads. “Firing nearly 1,200 dedicated ORD public servants across the country would decimate the scientific backbone of EPA which provides independent, objective, and unparallelled research that informs Agency assessments and decision-making,” they added. The letter featured the signatures of over 60 House Democrats including Reps. Nikema Williams (Ga.), Ro Khanna (Calif.), Summer Lee (Pa.), Don Beyer (Va.), Joe Neguse (Colo.), Jamie Raskin (Md.), Pramila Jayapal (Wash.) and Rashida Tlaib (Mich.). The Hill reported last week that the EPA was considering the cutting of its science arm and dropping most of the employees of the branch, per documents reviewed by Democratic staff for the House Science, Space and Technology Committee. The termination of the Office of Research and Development as an EPA National Program Office is called for in a plan reviewed by committee staffers. Fifty percent to 70 percent of the 1,540 staffers in the office would be cut under the plan. “While no decisions have been made yet, we are actively listening to employees at all levels to gather ideas on how to better fulfill agency statutory obligations, increase efficiency, and ensure the EPA is as up-to-date and effective as ever,” EPA spokesperson Molly Vaseliou said in a previous statement. In his letter, Landsman said dropping “the majority of ORD employees would be particularly harmful to EPA’s work to address industrial pollution, contaminated air and drinking water, environmental health, and worsening natural disasters.” The Ohio Democrat also questioned the EPA about the reasoning behind the staff cuts in the plan and the way the agency is prepping “to mitigate the loss of scientific expertise, institutional knowledge, and subject matter capacity resulting from this proposed action.” The Hill has reached out to the EPA for comment.

When a 1-in-100 year flood washed through the Coorong, it made the vital microbiome of this lagoon healthier

The 2022 floods triggered shifts in the Coorong’s microbiome—similar to our gut bacteria on new diets—revealing why freshwater flows are vital to wetland health.

Darcy Whittaker, CC BYYou might know South Australia’s iconic Coorong from the famous Australian children’s book, Storm Boy, set around this coastal lagoon. This internationally important wetland is sacred to the Ngarrindjeri people and a haven for migratory birds. The lagoon is the final stop for the Murray River’s waters before they reach the sea. Tens of thousands of migratory waterbirds visit annually. Pelicans, plovers, terns and ibises nest, while orange-bellied parrots visit and Murray Cod swim. But there are other important inhabitants – trillions of microscopic organisms. You might not give much thought to the sedimentary microbes of a lagoon. But these tiny microbes in the mud are vital to river ecosystems, quietly cycling nutrients and supporting the food web. Healthy microbes make for a healthy Coorong – and this unassuming lagoon is a key indicator for the health of the entire Murray-Darling Basin. For decades, the Coorong has been in poor health. Low water flows have concentrated salt and an excess of nutrients. But in 2022, torrential rains on the east coast turned into a once-in-a-century flood, which swept down the Murray into the Coorong. In our new research, we took the pulse of the Coorong’s microbiome after this huge flood and found the surging fresh water corrected microbial imbalances. The numbers of methane producing microbes fell while beneficial nutrient-eating bacteria grew. Populations of plants, animals and invertebrates boomed. We can’t just wait for irregular floods – we have to find ways to ensure enough water is left in the river to cleanse the Coorong naturally. Under a scanning electron micrograph, the mixed community of microbes in water is visible. This image shows a seawater sample. Sophie Leterme/Flinders University, CC BY Rivers have microbiomes, just like us Our gut microbes can change after a heavy meal or in response to dietary changes. In humans, a sudden shift in diet can encourage either helpful or harmful microbes. In the same way, aquatic microbes respond to changes in salinity and freshwater flows. Depending on what changes are happening, some species boom and others bust. As water gets saltier in brackish lagoons, communities of microbes have to adapt or die. High salinity often favours microbes with anaerobic metabolisms, meaning they don’t need oxygen. But these tiny lifeforms often produce the highly potent greenhouse gas methane. The microbes in wetlands are a large natural source of the gas. While we know pulses of freshwater are vital for river health, they don’t happen often enough. The waters of the Murray-Darling Basin support most of Australia’s irrigated farming. Negotiations over how to ensure adequate environmental flows have been fraught – and long-running. Water buybacks have improved matters somewhat, but researchers have found the river basin’s ecosystems are not in good condition. Wetlands such as the Coorong are a natural source of methane. The saltier the water gets, the more environmentally harmful microbes flourish – potentially producing more methane. Vincent_Nguyen The Coorong is out of balance A century ago, regular pulses of fresh water from the Murray flushed nutrients and sediment out of the Coorong, helping maintain habitat for fish, waterbirds and the plants and invertebrates they eat. While other catchments discharge into the Coorong, the Murray is by far the major water source. Over the next decades, growth in water use for farming meant less water in the river. In the 1930s, barrages were built near the river’s mouth to control nearby lake levels and prevent high salinity moving upstream in the face of reduced river flows. Major droughts have added further stress. Under these low-flow conditions, salt and nutrients get more and more concentrated, reaching extreme levels due to South Australia’s high rate of evaporation. In response, microbial communities can trigger harmful algae blooms or create low-oxygen “dead zones”, suffocating river life. The big flush of 2022 In 2022, torrential rain fell in many parts of eastern Australia. Rainfall on the inland side of the Great Dividing Range filled rivers in the Murray-Darling Basin. That year became the largest flood since 1956. We set about recording the changes. As the salinity fell in ultra-salty areas, local microbial communities in the sediment were reshuffled. The numbers of methane-producing microbes fell sharply. This means the floods would have temporarily reduced the Coorong’s greenhouse footprint. Christopher Keneally sampling for microbes in the Coorong in 2022. Tyler Dornan, CC BY When we talk about harmful bacteria, we’re referring to microbes that emit greenhouse gases such as methane, drive the accumulation of toxic sulfide (such as Desulfobacteraceae), or cause algae blooms (Cyanobacteria) that can sicken people, fish and wildlife. During the flood, beneficial microbes from groups such as Halanaerobiaceae and Beggiatoaceae grew rapidly, consuming nutrients such as nitrogen, which is extremely high in the Coorong. This is very useful to prevent algae blooms. Beggiatoaceae bacteria also remove toxic sulfide compounds. The floods also let plants and invertebrates bounce back, flushed out salt and supported a healthier food web. On balance, we found the 2022 flood was positive for the Coorong. It’s as if the Coorong switched packets of chips for carrot sticks – the flood pulse reduced harmful bacteria and encouraged beneficial ones. While the variety of microbes shrank in some areas, those remaining performed key functions helping keep the ecosystem in balance. From 2022 to 2023, consistent high flows let native fish and aquatic plants bounce back, in turn improving feeding grounds for birds and allowing black swans to thrive. A group of black swans cruise the Coorong’s waters. Darcy Whittaker, CC BY Floods aren’t enough When enough water is allowed to flow down the Murray to the Coorong, ecosystems get healthier. But the Coorong has been in poor health for decades. It can’t just rely on rare flood events. Next year, policymakers will review the Murray-Darling Basin Plan, which sets the rules for sharing water in Australia’s largest and most economically important river system. Balancing our needs with those of other species is tricky. But if we neglect the environment, we risk more degradation and biodiversity loss in the Coorong. As the climate changes and rising water demands squeeze the basin, decision-makers must keep the water flowing for wildlife.

Murphy, a Beloved Bald Eagle Who Became a Foster Dad, Dies Following Violent Storms in Missouri

A beloved bald eagle who gained popularity after incubating a rock is mourned after dying from head trauma sustained during violent storms in Missouri last week

A beloved bald eagle who gained popularity for incubating a rock in 2023 is being mourned Saturday after the 33-year-old avian died following intense storms that recently moved through Missouri. Murphy, who surpassed the average life span of 25 years, died last week at the World Bird Sanctuary in Valley Park, Missouri. Sanctuary officials believe the violent storms that ripped apart homes and claimed 12 lives last weekend may have factored in the bird's death. They said birds have access to shelters where they can weather storms and the sanctuary has contingency plans for different environmental situations. But evacuations weren't performed since no tornadoes approached the sanctuary. Three other birds who were in the same shelter with Murphy survived. A veterinarian performed a necropsy and found the bald eagle sustained head trauma. “We are unable to determine if Murphy was spooked by something and hit his head while jumping off a perch or if wind and precipitation played a part in the injury,” a statement shared by the sanctuary on social media said. Murphy lived in the sanctuary's Avian Avenue exhibit area and rose to prominence in 2023 when he incubated a rock. His instincts were rewarded when he was allowed to foster an injured eaglet that he nurtured back to health. The eaglet was eventually released back to the wild and another eaglet was entrusted to Murphy's care. The second eaglet is expected to be released into the wild this summer.“In honor of Murphy’s legacy, we plan to name the eventual eagle fostering aviary Murphy’s Manor, so that we can continue to remember him for decades to come,” the sanctuary's statement added.Copyright 2025 The Associated Press.
