    Pollution May Affect the Color of City Birds, Research Shows

    by

    Recent studies show that certain feather pigments can help neutralize toxic pollution. It means darker, duller birds could have a survival advantage.Some popular city dwellers appear to be losing their colorful allure, and not just the dirty birds.According to a study published this summer in the journal Landscape and Planning that looked at 547 bird species in China, birds that live in cities are duller and darker on average than their rural counterparts. A similar conclusion emerged from an analysis of 59 studies published in March in Biological Reviews: Urban feathers are not as bright, with yellow, orange and red feathers affected most.Often, city birds are covered in grime. But even if you could give them all a good bird bath, chances are their brightness still wouldn’t match that of their country cousins. That’s because of the way pollution, and heavy metals in particular, can interact with melanin, a pigment that makes feathers black, brown and gray.Studies show that melanin can bind to heavy metals like lead. That means toxic chemicals may be more likely to be stored in plumage in darker and duller birds. And that, in turn, can confer a survival advantage.“The more melanin you accumulate, the better able you are to sequester these harmful compounds in feathers,” said Kevin McGraw, a biologist at Michigan State University who studies the colors of animals to understand the costs, benefits and evolution of visual signals.Urban pollution affects avian colors in other ways, too. Research shows that compared with rural plants, city trees store fewer natural pigments called carotenoids, and pollution is the likely reason. Carotenoids are produced by plants, algae and fungi. They’re what makes red peppers red and carrots orange.When leaves are low on these pigments, the effects go up the food chain: Leaf-munching caterpillars become deficient in carotenoids, and so do caterpillar-munching birds.We are having trouble retrieving the article content.Please enable JavaScript in your browser settings.Thank you for your patience while we verify access.

      Mr. Greedy, an African Penguin With 230 Descendants, Dies at 33

      by

      An African penguin who left many offspring in his long life, he belonged to the largest colony of the aquatic bird species in North America, according to the zoo.The popular African penguin known as Mr. Greedy, a fixture of the Maryland Zoo who had sired many offspring and left “an astounding 230 descendants” over five generations, has died after an age-related decline in his health, the zoo said in a statement.He was 33 — yes, in human years. (The zoo said it had no accurate way to determine the equivalent in penguin years.) He was the oldest penguin in his colony, which the zoo said is the largest in North America.When he was not busy reproducing or bringing joy to zoo visitors, Mr. Greedy swam hard, took care of his mate — nicknamed Ms. Greedy — and was constantly looking for things to steal.His mischievous ability to steal nesting materials and food from others had earned him the affectionate nickname by which he was known, Jen Kottyan, the bird curator at the zoo, said in a phone interview on Saturday.Mr. Greedy, born in 1991, had a more official, though less personable name: African penguin No. 821. The cause of death was euthanasia on Aug. 27, the zoo said.In his long life, Mr. Greedy “made a tremendous contribution to his endangered species,” said the statement from the Maryland Zoo, which is in Baltimore.We are having trouble retrieving the article content.Please enable JavaScript in your browser settings.Thank you for your patience while we verify access.

      Angry Birds Take on Drones at New York City Beach

      by

      American Oystercatchers are attacking drones that have been deployed to scan for sharks and swimmers in distress.One is a distinctive shorebird, slightly smaller than an average sea gull, with a bright orange bill that pries open clams, oysters and other shellfish. The other is a remote-controlled gadget with rotating blades.In the skies above Rockaway Beach in Queens, bird and drone are not, it seems, coexisting in harmony.Just as New Yorkers flock to the beach to escape the sweltering summer heat, American Oystercatchers have taken to attacking a fleet of drones deployed by city officials to scan for sharks and swimmers in distress.The aerial conflict between animal and machine is raising concerns about the safety of the shorebirds, as they aggressively pursue the buzzing drones in defense of their nests, city officials and bird experts said.“They fly toward the drone, they’ll vocalize, and they might even try to swoop at it,” said Katrina Toal, deputy director of the wildlife unit at the New York City Department of Parks and Recreation. “The danger is to the birds, of course. They could strike the drone, injuring themselves.”The display of a shark-monitoring drone controller provides an aerial view of Jones Beach.Michael M.

      SpaceX’s Assault on a Fragile Habitat: Four Takeaways From Our Investigation

      by

      The development of Elon Musk’s facility in South Texas did not play out as local officials were originally told it would.When Elon Musk first eyed South Texas for a new base of space operations, he promised that SpaceX would have a small, eco-friendly footprint and that the surrounding area would be “left untouched.”A decade later, the reality is far different. An investigation by The New York Times shows how SpaceX’s ferocious growth in the area has dramatically changed the fragile landscape and has threatened the habitat that the U.S. government is charged with protecting there.More repercussions are likely coming, in South Texas and in other places where SpaceX is expanding. Mr. Musk has said he hopes to one day launch his Starships — the largest rocket ever manufactured — a thousand times a year.Executives from SpaceX declined repeated requests to comment. But Gary Henry, who until this year served as a SpaceX adviser on Pentagon launch programs, said the company was aware of concerns about SpaceX’s environmental impact and was committed to addressing them.Here are four takeaways from our investigation:Musk used preserved lands as a buffer for SpaceX operationsRocket launch sites in the U.S., such as Vandenberg Space Force Base in California and Kennedy Space Center in Florida, typically are enormous, secure facilities with tens of thousands of acres within their confines.Mr. Musk didn’t intend to buy up anything like that amount of land when he was looking at the area near Brownsville, Texas. Instead, he wanted to buy a tiny piece of property in the middle of public lands — what the team involved referred to as a “doughnut hole.” He figured the surrounding state parks and federal wildlife preserves would serve as natural buffers.We are having trouble retrieving the article content.Please enable JavaScript in your browser settings.Thank you for your patience while we verify access.

      The Disease Detectives Trying to Keep the World Safe From Bird Flu

      by

      As Dr. Sreyleak Luch drove to work the morning of Feb. 8, through busy sunbaked streets in Cambodia’s Mekong river delta, she played the overnight voice messages from her team. The condition of a 9-year-old boy she had been caring for had deteriorated sharply, and he had been intubated, one doctor reported. What, she wondered, could make the child so sick, so fast?“And then I just thought: H5N1,” she recalled. “It could be bird flu.”When she arrived at the airy yellow children’s ward at the provincial hospital in Kratie, she immediately asked the child’s father if the family had had contact with any sick or dead poultry. He admitted that their rooster had been found dead a few days before and that the family had eaten it.Dr. Luch told her colleagues her theory. Their responses ranged from dubious to incredulous: A human case of avian influenza had never been reported in their part of eastern Cambodia. They warned her that if she set off the bird flu warning system, many senior government officials might get involved. She risked looking foolish, or worse.Anxious but increasingly certain, Dr. Luch phoned the local public health department, located just across the street. Within minutes, a team arrived to collect a sample from the child, Virun Roeurn, for testing in a lab.By then, Virun’s distraught parents had lost faith in the hospital. They demanded that he be sent by ambulance to the capital, Phnom Penh. His flu swab sample traveled with him.Virun died on the journey. At 8 p.m., Cambodia’s National Public Health Laboratory confirmed Dr. Luch’s suspicion: He had died of highly pathogenic avian influenza.We are having trouble retrieving the article content.Please enable JavaScript in your browser settings.Thank you for your patience while we verify access.

      The Beautiful World of Birding

      by

      More from our inbox:Civility on the Court, but These Are Not Civil TimesA History of Deception About Politicians’ HealthTest the CandidatesBanning Plastic Foam Nadine RedlichTo the Editor:Re “Birds Open Our Eyes and Ears,” by Ed Yong (Opinion guest essay, March 31):Mr. Yong has written a marvelous article that will resonate with many birders, especially in these troubled times. Many are the mornings when I’ve put aside reading the news in favor of watching the birds at my home in southeast Arizona.To Mr. Yong’s article I would add that seeking and identifying new birds are wonderful ways to experience the world. Spending time getting to know the birds you’ve already seen can be equally fulfilling, if not even more so.People who don’t have the luxury of traveling to find exotic species need not feel deprived; they can find fulfillment creating a songbird habitat in their backyard.Craig CorayPatagonia, Ariz.To the Editor:Thank you for the wonderful birding article. I too have become obsessive, and I am learning the names of different birds.The positive healthy aspects of birding are obvious, but people should not just get to know birds, but also think about their safety and their food. Sanctuary and breeding grounds are being depleted around the world. Shorelines are being paved and water conditions are subpar.Birds are not just for us to enjoy, enhancing our photo albums or improving our species lists. Stay a distance from their habitats, and don’t let your dog or cat tread on them. Get protected glass for buildings.

      Bird Flu Spreads to Dairy Cows

      by

      U.S. regulators confirmed that sick cattle in Texas, Kansas and possibly in New Mexico contracted avian influenza. They stressed that the nation’s milk supply is safe, saying pasteurization kills viruses.A highly fatal form of avian influenza, or bird flu, has been confirmed in U.S. cattle in Texas and Kansas, the Department of Agriculture announced on Monday.It is the first time that cows infected with the virus have been identified.The cows appear to have been infected by wild birds, and dead birds were reported on some farms, the agency said. The results were announced after multiple federal and state agencies began investigating reports of sick cows in Texas, Kansas and New Mexico.In several cases, the virus was detected in unpasteurized samples of milk collected from sick cows. Because pasteurization kills viruses, officials emphasized that there was little risk to the nation’s milk supply.“At this stage, there is no concern about the safety of the commercial milk supply or that this circumstance poses a risk to consumer health,” the agency said in a statement.Outside experts agreed. “It has only been found in milk that is grossly abnormal,” said Dr. Jim Lowe, a veterinarian and influenza researcher at the College of Veterinary Medicine at the University of Illinois at Urbana-Champaign.In those cases, the milk was described as thick and syrupy, he said, and was discarded. The agency said that dairies are required to divert or destroy milk from sick animals.We are having trouble retrieving the article content.Please enable JavaScript in your browser settings.Thank you for your patience while we verify access.

      Man Pleads Guilty in ‘Killing Spree’ of Bald Eagles in Montana

      by

      Travis John Branson of Washington State was indicted last year for illegally hunting and selling the birds. A co-defendant is still on the run.One of two men accused of shooting 3,600 birds in Montana, including bald and golden eagles, in an illegal “killing spree” pleaded guilty to taking part in a scheme to sell the dead birds on the black market, federal prosecutors said on Wednesday.In a plea deal, Travis John Branson, 48, of Washington State, pleaded guilty to one count of conspiracy, two counts of illegally trafficking bald and golden eagles, and one count of violating the Lacey Act, a federal law prohibiting the sale of illegally acquired wildlife, the United States Attorney’s Office for the District of Montana said.Mr. Branson faces up to five years in prison and a $250,000 fine for the conspiracy and Lacey Act charges, prosecutors said.In December, a grand jury indicted Mr. Branson and his co-defendant Simon Paul, 42, of Montana, on 15 counts, most of them for illegal trafficking of eagles. Prosecutors agreed to drop 11 of those counts for Mr. Branson, according to the plea agreement.Mr. Paul, who did not appear at his arraignment, prosecutors said, is still on the run. His sentencing is set for July 31 at the U.S. District Court in Montana, prosecutors said.From January 2015 to March 2021, the two men routinely met on the prairies of the Flathead Indian Reservation in western Montana to hunt eagles that they would later sell, prosecutors said. Mr. Branson would travel from Washington State to meet Mr. Paul on the reservation, where he lived, prosecutors said.The men sold the eagles’ wings, tails and, on one occasion, a whole eagle, according to the indictment. Prosecutors did not say how much money the men made from sales, noting only that the bird parts were sold for “significant sums of cash.”At one point they devised a hunting strategy in which they set out a deer carcass to lure in the birds, according to the indictment, which also quoted text messages between Mr. Branson and buyers.In one message, Mr. Branson told a buyer that he was “on a killing spree” to stock up on eagle tail feathers. In another, he wrote that he was out “committing felonies,” according to the indictment.He also seemed to acknowledge in a separate message that shipping the birds internationally was illegal, prosecutors said.Mr. Branson’s public defender, Andrew J. Nelson, could not immediately be reached for comment on Wednesday evening. Messages left at a phone number and sent to an email address listed for Mr. Branson were immediately returned.A lawyer listed in court records for Mr. Paul declined to comment.The killing of bald eagles was seen as particularly flagrant in a country where the bird is the national symbol and was once considered an endangered species.It was unclear how many of the 3,600 birds prosecutors said the men killed were eagles. Clair J. Howard, a spokeswoman for the U.S. attorney’s office, declined to comment. More

      Pigeon Collared as a Possible Chinese Spy Is Freed After 8 Months

      by

      Animal rights activists in Mumbai celebrated an end to the “wrongful imprisonment” of a mystery bird that a detective concluded was probably a lost racer from Taiwan.Suspicion of foreign espionage, cursive messages in ancient Chinese, a sensitive microchip — and a suspect that could not be stopped at the border.Ravindar Patil, the assistant Mumbai police sub-inspector assigned to the case, was scratching his head for answers. But first, he had to find a place to lock up the unusual captive.So he turned to a veterinary hospital in the Indian metropolis, asking it to retrieve a list of “very confidential and necessary” information about the suspect — a black pigeon caught lurking at a port where international vessels dock.“The police never came to check the pigeon,” said Dr. Mayur Dangar, the manager of the hospital.After eight months, the bird was finally set free this week, its innocence of spying for China long confirmed through crack detective work, but the jail doors flung open only after a newspaper report, repeated letters to the police by the veterinary hospital, and intervention from an animal rights group.The group, PETA India, celebrated what it called the end of a “wrongful imprisonment.”“PETA India handles 1,000 calls a week of animal emergencies, but this was our first case of a suspected spy who needed to be freed,” said Meet Ashar, who leads the organization’s cruelty response division.Mr. Ashar said the case had put the hospital’s staff members in a dilemma: They didn’t want to expose a healthy bird to the sick and injured, but they also couldn’t set it free because “it was such a high-profile case and the charge was so serious.”We are having trouble retrieving the article content.Please enable JavaScript in your browser settings.Thank you for your patience while we verify access.
