An online tool called BirdNET uses artificial intelligence to identify bird songs and calls. And Cornell’s well-known Merlin Bird ID app now has sound ID, too. It’s as simple as opening the app, choosing “Sound ID,” and hitting record. It can pick out multiple species in the same recording…

Since 1976, Project FeederWatch has been through many changes and iterations. But what has remained is the dedication to collecting data that undeniably improves bird science. In this episode, host Deja Perkins speaks with Emma Greig, the U.S. Project Leader for FeederWatch, about what…

During migration, Snow Geese gather in the tens of thousands. They coordinate their movements, flying in a big, compact flock, which makes it harder for a predator to pick off a single bird. It is truly something to see.

Long, upward slopes called escarpments offer a good chance of seeing some of the many raptor species found in Belize. Shaped like a compact Red-tailed Hawk, White Hawks are white overall with black markings and scan the landscape for reptile prey. Bat Falcons have a darkly barred chest and…

A female Wood Thrush will carefully choose each piece of nest-building materials because her eggs will depend on it for warmth and protection. But even the best-made nest couldn’t exist without the support of a sturdy shrub or tree. Much like a bird’s nest, BirdNote depends on having a…

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…
