Chat, a genus of warblers (icteria), placed by Baird in the subfamily sylvicolino2. The best known species is the yellow-breasted chat (I. viridis, Bonap.). The bill is shorter, stronger, and more curved than in the typical warblers, in this respect more nearly resembling the vireos and the shrikes. The upper parts are olive-green; under parts and inside of wings gamboge-yellow for anterior half of body; rest of under parts white, tinged with brown on the sides; forehead and sides of head ash; lores and region below the eyes blackish; a white stripe from the nostrils over the eye; patch on lower lid, and stripe from side of lower mandible, white; bill black. Female like the male, but smaller. Length 7'4 in., tail 3.3, wing 3.25. It is found over the eastern United States to the Missouri, and south to Guatemala. The long-tailed chat (L longicauda, Lawr.) differs from the above chiefly in having the tail nearly half an inch longer; it may be only a western variety. They are very noisy birds, jealous of intruders, and apparently scolding in a great variety of notes. The food consists principally of insects.
They are most abundant in the middle and southern states, and are peculiar to America. (See Stone Chat.)
