palm-chat, (species Dulus dominicus), songbird of Hispaniola (Haiti and the Dominican Republic) and nearby Gonâve Island, which may belong in the waxwing family (Bombycillidae) but which is usually separated as the family Dulidae. This 19-centimetre (7.5-inch) bird has a stout bill, and its plumage is greenish brown above and whitish, with dark streaking, below (in both sexes). Palm-chats feed in flocks on berries and flowers. They build a large communal nest in a tree, with a private-entrance chamber for each of up to 30 pairs.
