The Andean Condor is one of the largest flying birds in the world. With a wingspan that can stretch over 10 feet across, the condor doesn’t flap so much as sail, using rising thermals to glide across the Andes for hours. Once revered in Inca mythology as a messenger of the gods, the Andean Condor now graces the coat of arms of Bolivia, Chile, Colombia, and Ecuador. But like many scavengers, condor populations are declining due to threats like lead poisoning and habitat loss.More info and transcript at BirdNote.org.Want more BirdNote?

Palmyra Atoll is a ring-shaped island encircling a lagoon in the South Pacific. The atoll lost many native trees due to U.S. military activity during World War II. Conservationists have worked to restore the ecosystem. Seabirds such as Black Noddies and Red-footed Boobies nest in the island’s rainforest.

There are five million bird eggs stowed away in museums across the world — and the study of eggs, called oology, can give us great insight into birds.
