Crane Hawks of Central and South America and African Harrier-Hawks both have legs that bend forward and backward. Each bird’s wonderfully peculiar leg adaptation is completely original — it evolved all on its own — even though the end result is the same. It's a fascinating example of a phenomenon called convergent evolution.More info and transcript at BirdNote.org.Want more BirdNote? Subscribe to our weekly newsletter.

Protecting the Madagascar Fish-Eagle
Biodiversity conservationist Lily-Arison Rene de Roland works with some of the rarest birds in the world. He’s the Madagascar program director for the Peregrine Fund, a non-profit conservation organization that protects imperiled birds of prey like the Madagascar Fish-Eagle. These large raptors only eat fish, which means they rely on the same diminishing wetlands and natural resources as some fishing communities. In this episode, Lily shares how community-centered conservation programs are helping to support Madagascar’s fishers and fish-eagles.More info and transcript at BirdNote.org.Want more BirdNote?

Common Potoo: Branch or Bird?
Common Potoos are champions of camouflage. In the daytime these nocturnal creatures perch perfectly still on branches: heads pointed upward, bodies outstretched, and eyes closed down to tiny slits. It’s hard to tell where the branch ends and the bird’s body begins — which helps them avoid predators. They’re birds more often heard than seen; with a melodious but mournful song, made at dawn, dusk and by the light of the moon. The song earned potoos the name ‘Poor-me-one’ in Trinidad and Tobago.More info and transcript at BirdNote.org.Want more BirdNote? Subscribe to our weekly newsletter.

The Gyrfalcon – A Circumpolar Raptor
Gyrfalcons are circumpolar, nesting in the far north of Asia, North America, and Europe, including Iceland and Greenland. They evolved as a distinct species in the Pleistocene Era, around 100,000 years ago. Their large size and warm feathering gave them an edge for nesting high in the Arctic. Gyrfalcons reuse the same nesting site year after year, and some nests have been occupied for 2,500 years!More info and transcript at BirdNote.org.Want more BirdNote?

Jane Kim and the Wall of Birds
Walk into the visitor center at the Cornell Lab of Ornithology and you’ll be greeted by a massive mural called the Wall of Birds. About the size of a tennis court, the mural shows a map of the world covered in 270 life-sized portraits of birds and their relatives — ranging in size from the 30-foot-long, feathered dinosaur Yutyrranus hauli to the tiny Marvelous Spatuletail hummingbird. Artist and scientific illustrator Jane Kim partnered with the Cornell Lab to create this epic celebration of the evolution and diversity of birds, which was completed in December 2015.Read more about Jane in Field Notes!More info and transcript at BirdNote.org.Want more BirdNote?
