- 1Utah mink farm bird flu outbreak left unchecked, advocates say●'Watch them die': Bird flu outbreak at Utah mink farm largely unchecked, advocates say
Animal welfare advocates say an avian influenza outbreak at a Utah mink farm has gone largely unchecked, accusing authorities of failing to intervene as animals fell ill. Critics are calling for stronger oversight of mink farms, which have previously been flagged as sites where bird flu can spread and potentially adapt to mammals, raising public health concerns.
- 2Ospreys are vanishing along the US East Coast▼Ospreys are disappearing along the East Coast. Scientists think they know why.
Osprey populations are declining along the US East Coast, and scientists say they have identified a likely cause. The Washington Post reports on new research into why the fish-eating hawks, once a conservation success story, are disappearing from parts of their coastal range, raising concern among conservationists about the health of coastal ecosystems.
- 3Wildfire Smoke Poses Growing Health Threat to People and Birds●Smoke from Wildfires Is a Growing Health Threat to Both People and Birds
Health experts and conservationists warn that wildfire smoke has become a growing threat to both human and bird health. Fine particulate matter in smoke can damage lungs, aggravate respiratory and heart conditions, and harm birds, which are especially sensitive to air pollution. Researchers say longer, more intense wildfire seasons are expanding exposure to dangerous smoke across wider regions.

New research reported this week indicates that periods of climate change triggered rare, rapid bursts of evolutionary diversification in birds. The findings suggest that shifting environments repeatedly pushed bird lineages to adapt and split into new species, rather than evolving at a steady pace. Scientists say the work helps explain why bird diversity is distributed unevenly across the globe and how species may respond to today's warming climate.
- 5Florida deploys robot rabbits to fight invasive pythons▼When a district in Florida used robot rabbits to eliminate growing population of Burmese pythons and prot
A Florida district is using robotic rabbits to help control the growing population of Burmese pythons, an invasive species threatening local wildlife such as protected mammals and birds. The decoys mimic prey to lure the snakes into traps, offering a novel tool in the state's long-running effort to curb the pythons' spread in the Everglades region.
- 6Cuckoo Genetics Show Host Habits Alone Don't Split Species●Cuckoo Genes Reveal Host Habits Alone Cannot Divide a Wandering Species
New genetic research on cuckoos indicates that differences in host preferences are not enough on their own to divide the wide-ranging birds into separate species. The findings suggest that despite specialised egg-laying habits targeting different host birds, gene flow across populations keeps the wandering species genetically unified, complicating how scientists classify parasitic cuckoo lineages.
- 7Avian keratin disorder blamed for deformed beaks in Alaska chickadees▼Scientists believe avian keratin disorder is cause of fishhook beaks in Alaska chickadee population
Scientists in Alaska say avian keratin disorder is behind the fishhook-shaped beaks appearing in the state's chickadee population. The condition causes abnormal growth of the birds' beaks, which can make feeding difficult. Researchers studying the disorder are working to understand its causes, and the findings have drawn attention given the unusual number of affected birds reported in the region.
- 8Young New Zealanders driving a birding boom●There’s a fantastic article on the front page of the # RNZ website this morning about the rise of birding amongst young
RNZ is featuring a front-page article on the growing popularity of birding among young people in New Zealand. Young birders are becoming significant contributors to citizen science platforms eBird and iNaturalist, with one enthusiast quoted saying he does not mind getting wet, rained on or muddy in pursuit of birds. Readers online are praising the coverage and celebrating the trend.
