To figure out the source of a hummingbird’s hum, scientists built a special rig to measure air pressure, twelve high-speed cameras, and over 2,000 microphones to observe hummingbirds fluttering in place at an artificial flower. The researchers found that the hum derives from the difference…

Some migratory songbirds such as European Robins have special light-sensitive proteins called cryptochromes in their eyes. New research suggests how the cryptochromes could alter their behavior in the presence of magnetic fields, giving birds a visual cue for north and south. Other birds…

In 2023, over 120 contributors published a study in the scientific journal, Ornithological Applications, about a long history of exclusion Latin American and Caribbean scientists have faced. In the world of ornithology, the Global North (or rich and powerful regions like the USA, Canada…

When a Northern Saw-whet Owl spreads its wings, many birds can see something our human eyes can’t: the owl’s flight feathers glow with ultraviolet light. It’s invisible to humans without the help of a UV blacklight. While the glowing feathers on parrots might help them attract mates, the…

In Lafayette Park in St. Louis, Missouri, a dozen or so Eurasian Tree Sparrows from Germany were released. But unlike other introduced species such as the similar-looking House Sparrow, they did not spread very far and remained in a limited area in the Midwest. It’s not fully clear why…

Birds called prions have an especially creative approach to getting their food. They pass seawater through their mouths and filter it to catch tiny animals such as krill and other small crustaceans. It’s similar to how baleen whales feed, leading to the prion’s nickname: the whale-bird…

During migration, some birds change orientation, often by a full 180 degrees, and travel almost the same distance — but in the opposite direction — as the rest of their species. The phenomenon is called misorientation. First-year birds are particularly susceptible. Many vagrant birds never…

On October 5, 2023, thousands of migrating songbirds died after crashing into the McCormick Place Convention Center in downtown Chicago and surrounding buildings. Co-host Deja Perkins will speak with Douglas Stotz, a conservation ecologist at the Chicago-based Field Museum about that…

Rosa Malagon grew up believing that birds hold spiritual significance, thanks to teachings from her Mexican heritage that her mother would share. Now working for the Hispanic Access Foundation, Rosa helps connect Latino-led nonprofits with funding from the U.S. Forest Service. She also…

The White-vented Storm-Petrel is a small black and white seabird found off the coasts of Chile and Peru. Storm-petrels spend their entire lives at sea, except when nesting. Scientists had long been mystified about just where this species nests. A search lasting eight years led them to a…
