Appearance
It is a large bird, some 63–74 cm in length, and similar in general appearance to a slim turkey with thin neck and small head. ''Pipile jacutinga'' is mainly black with a bluish gloss; it has a conspicuous white wing patch bearing 3 neat rows of tiny black dots. The large crest is whitish, and it has a red throat wattle with a dark blue patch at the front. Its naked whitish eye-ring and black-feathered face and forehead are unique in its genus. The legs and feet are red.
Distribution
No other piping guan is found in its range, though the Gray's piping guan approaches it in Paraguay. This bird has a pale bluish pendulous wattle, a smaller wing patch, and an entirely naked white face and white forehead.References:
