Phoenicopterus chilensis

The Chilean flamingo is about 41 inches tall (the male is somewhat larger than the female) and weighs approximately 5 pounds. It is lighter in color than other flamingo species, with pink edges on its outer wings and black under-feathers. It has bright red knees and feet. The neck and legs are longer in proportion to its body than any other species of bird. The 3 front toes are fully webbed, and its hind toe is elevated. It has a unique bill: the lower beak is the larger of the 2 and the upper beak fits into the lower like a lid. Broad areas of the beaks have fine comb-like teeth (lamellae). The young are grayish brown when born and do not look like the adult for 3 to 4 years.
