Gerrit Vyn is a sound recordist for the Cornell Lab of Ornithology. He recently traveled to northeastern Brazil’s Araripe Plateau in search of the Araripe Manakin, a beautiful white bird with dark wing-tips and tail-feathers — and a deep red hood. The Araripe Manakin is critically endangered, in part because of its limited range. But, as Gerrit observes, human activity also threatens the bird’s survival. Learn more at BirdNote.org.
