It is about 60 cm long, with a small head with a long crest and a thin neck. It has large wings and a wide, long tail. The plumage of the male and female is the same, with a brown body with white stripes on the upper side and reddish yellow on the underside. It is found in northern South America, living in flocks of about 5 to 10 pairs in mangrove forests along the Amazon and Orinoco river basins. This bird's bursa, which is supposed to store food, is particularly enlarged and large, with thick walls, and food is ground up in the bursa.
