About Chauna chavaria (Linnaeus, 1766)
The northern screamer, scientific name Chauna chavaria (Linnaeus, 1766), measures 76 to 91 cm (30 to 36 in) in length. It has a stout body, a disproportionately small head, and a gray bill. Males and females have identical plumage. Adult northern screamers have a gray crown with a long crest, a mostly white face, a wide black band around the neck, and dark gray body, wings, and tail. Each wing has two sharp spurs at the manus. Bare red skin surrounds the brown eye, and the legs and feet are reddish orange. Juveniles look similar to adults but have duller plumage. The northern screamer ranges across northern Colombia, from the Atrato River and Magdalena River valleys east into the Lake Maracaibo area of Venezuela. It lives in a variety of wet landscapes, including swamps, marshes, lagoons, riverbanks, and seasonally flooded river plains.
