Groove-billed Anis gather in loose groups. And with good reason. They nest communally. As many as four or five pairs of birds may use one nest, a bulky cup of twigs lined with fresh leaves. When the dominant female ani begins to lay her own eggs, the other females lay simultaneously. Up to 20 chalky white eggs have been found in one nest. All parents share the duties of incubating and raising the young. World Birding Centers and the Rio Grande Joint Venture are striving to protect and restore their habitat.More info and transcript at BirdNote.org. Want more BirdNote?
