 wrinkled folds, along the side of the neck, the supplemental wings, at the same time, 

 as well as when the bird is flying, lying along the neck. But when these bags are

 words. The sound consists of three notes, of the same tone, resembling those produced 

 by the night hawks in their rapid descent, each strongly accented, the last being twice 

 as long; as the others."
