Every summer, puffins — like this Horned Puffin — grow blazingly colorful layers over the bases of their huge beaks. But in the winter, puffins lead very different lives, and they shed their bright ornamentation. Puffins in winter are largely solitary — and silent. They spend about seven months alone at sea, before returning once again to their colonies to breed.More info and transcript at BirdNote.org.Want more BirdNote? Subscribe to our weekly newsletter.

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.

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 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.

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?
