  1. Native Western Australian birds are the composers and stars of an engaging new music project at Edith Cowan University. View the full article
  2. The interior least tern, a hardy Midwestern bird that survived a craze for its plumage and dam-building that destroyed much of its habitat, has soared off the endangered species list. View the full article
  3. The first Philippine eagle bred in captivity in an effort to save one of the world's most endangered birds has died from infections, conservationists said Friday. View the full article
  4. Companies in the petroleum and other industries will not be held legally responsible for killing migratory birds as long as they did not mean to, the Trump administration said Tuesday, drawing swift condemnation from animal welfare and conservation groups. View the full article
  5. The simple things in life sometimes bring the greatest joy—like feeding the ducks at your local pond. The next time you pay your feathered friends a visit, consider introducing some variety into the food you give them. Just like for us humans, a balanced diet is important for wild animals. The large amounts of bread that people feed wild birds may be well-intentioned, but they could be doing them harm. View the full article
  6. Since learning to capture birds as a teen, Muhammad Rafiq has amassed a small fortune in Pakistan trapping and trafficking falcons—including some endangered species—for wealthy Gulf Arabs. View the full article
  7. The coronavirus pandemic is coming home to roost in America's backyards. View the full article
  8. In the mountains across the world, different types of vegetation occur at different elevations creating distinct zones with well-defined borders between them. Each vegetation zone provides specific living conditions for animals. Therefore species that are adapted to habitats created in the specific zone occur only at the specific elevations and do not overlap with other species of similar ecology and behavior adapted to other vegetation zones at different elevations. This zonation is believed to be especially true for ecologically similar species that narrowly specialize to use specific resources and therefore compete with each other if they co-occur next to each other in the same habitat.

  9. In many animals, female preference for males with the most elaborate appearance is an important factor in the evolution of bright and dramatic colors. View the full article
  10. Many animal species use social information—from conspecifics or other species—to inform their behavioral choices, for example where to look for food or build a nest. In a recent study, ornithologists have shown for the first time that the ability to use such information can depend on an individual's cognitive skills. In the collared flycatcher, females that mastered a learning task faster were more likely to copy the nest site choices of great and blue tits in the same area. View the full article
  11. An analysis of the songs of most of the world's passerine birds reveals that the frequency at which birds sing mostly depends on body size, but is also influenced by sexual selection. The new study from researchers of the Max Planck Institute for Ornithology and colleagues suggests that habitat characteristics do not affect song frequency, thereby refuting a long-standing theory.

  12. Scientists know that biodiversity is declining across much of the world although less universally and dramatically than we feared. We also know that things are likely to get worse in the future, with a combination of habitat loss, climate change and overexploitation set to drive species and habitats ever closer to extinction.

  13. A new study from scientists at the Cornell Lab of Ornithology examines public attitudes toward non-native bird species and whether people are willing to manage them to protect native cavity-nesting birds, such as Eastern Bluebirds and the American Kestrel. The findings are published in the Journal of Environmental Management. View the full article
  14. The global food system could drive rapid and widespread biodiversity loss if not changed, new research has found. View the full article
  15. Local authorities in rural Egypt have declared a state of emergency after detecting two outbreaks of bird flu. View the full article
  16. The world is changing in dramatic ways, especially in the High Arctic. Climate change has meant that spring arrives earlier, but winters have become far more treacherous for Arctic animals that overwinter there, with more rain and ice. View the full article
  17. Red tide is back in the waters off of Florida's southwest coast, making birds sick and killing fish, according to a state environmental agency update on Wednesday. View the full article
  18. A bird that since John James Audubon's time has scurried under the radar of all but the most attentive ornithologists, conservationists and naturalists has received protection from the U.S. Fish and Wildlife Service. View the full article
  19. Eastern Australia's wetlands and waterbirds have partially recovered from the drought—but long-term trends remain concerning, an aerial survey by UNSW researchers has revealed. View the full article
  20. If you thought your morning hike was contributing to your wellbeing, a new study shows that you're right, especially if our avian friends were singing while you strolled. View the full article
  21. A comprehensive new study into the key user groups in Indonesia's bird trade offers hope for protecting species through behavioural change. Novel research led by Manchester Metropolitan University (MMU) and Chester Zoo has identified three main groups within the Indonesian songbird owner community: 'hobbyist', 'contestant' and 'breeder'.

  22. Scientists have found the most elaborately dressed-to-impress dinosaur ever described and say it sheds new light on how birds such as peacocks inherited their ability to show off. View the full article
  23. Back in 2012, Ryan Terrill was hiking down a dry canyon in central Bolivia, looking for Giant Antshrikes—the largest species of antbird—but he found himself, instead, thinking about another bird: the Titicaca Grebe. View the full article
  24. New research has shown just how picky the iconic superb parrot is about the types of tree hollows they nest in, with the discovery potentially key to protecting the threatened species. View the full article
  25. As migratory birds travel back and forth between their breeding and wintering grounds twice each year, they face many hazards. For species that migrate during the night, one of those dangers is the disorienting influence of light pollution from cities. A new study in the journal Environmental Pollution examines how artificial light at night and urban landcover are associated with the presence of nocturnal migrants across seasons.
