Capuchinbirds — Singing in Captivity

The Capuchinbird's "song" is so un-birdlike it is difficult to imagine the birds producing these sounds. This video captures one male singing — notice his stiff upright posture, his inflating and deflating body, and especially the odd tuft of feathers he is displaying near his tail. The origin of this video is unclear; it appears to be an amateur video of some birds in a zoo or aviary, published on Sep 7, 2012.
