Curassow

   Curassow is any of several long-tailed birds that live in the mountains of South America and Central America. Curassows are slightly lighter in weight than turkeys and range in length from 20 to 40 inches. They have an erectile crest of stiff, curled feathers on their heads and sometimes a bright-colored bill. In some species, including the great curassow (Crax rubra), a fleshy yellow protuberance, or knob, grows on the forehead. In this species, the male is black with a white belly, and the female is reddish brown.
   Curassows live in dense forests, often in large groups. They feed on vegetation, insects, and worms.
   Curassows are classified in the order Galliformes, family Cracidae.
