Most of the bird sounds you hear on BirdNote come from the Macaulay Library, a vast collection of over one million bird calls and songs curated by the Cornell Lab of Ornithology. The library relies on both professional field recordists and dedicated volunteers to capture the sounds of…

The Santa Marta Sabrewing is a hummingbird species so rare, they’ve only been documented twice in recent years. Native to the mountains of Colombia, they were officially described in 1946. No one reported another sighting until 2010. They became a “lost” species, eluding every attempt to…

The Magellanic Plover is known for being a bit of an oddball. These shorebirds have a round body like a dove and even feed their young with milk produced in a part of their digestive system called the crop — a rare trait they share with doves. But genetic data revealed that Magellanic…

Ornithologist Bill Evans has helped us better understand the sounds that birds make as they migrate at night. Known as nocturnal flight calls, many species can be identified based on their signature sound. Using special handmade microphones left outside overnight, Evans, his colleagues and…

The colorful feathers and loud songs of male songbirds often catch a birder’s attention first. Observing females often means birding more slowly, noticing subtle differences in plumage and behavior, says Joanna Wu, who’s part of a group called the Galbatrosses that’s encouraging birders to…

Many bird species can eat the fruits of plants that are toxic to humans — even the white berries found on poison ivy. These birds just aren’t sensitive to the compounds in the berries that are irritating or poisonous to people. While you probably want to stay away from poison ivy, you can…

Many birds have an excellent sense of smell. And the odors that birds make can act as mating signals for some species. The source for many of these scents, says biologist Danielle Whittaker, are the microbes that live in birds’ preen oil, which they use to keep their feathers in good…
