The Groove-billed Ani, Crotophaga sulcirostris, is an odd-looking tropical bird in the cuckoo family with a long tail and a large, curved beak. It is a resident species throughout most of its range, from southern Texas and central Mexico through Central America, to northern Colombia and Venezuela, and coastal Ecuador and Peru. It only retreats from the northern limits of its range in Texas and northern Mexico during winter.The Groove-billed Ani is about 34 cm (13 in) long, and weighs 70-90 g (2.5-3.2 oz). It is completely black, with a very long tail almost as long as its body. It has a huge bill with horizontal grooves along the length of the upper mandible. It is very similar to the Smooth-billed Ani, some of which have bills as small as the Groove-billed and with grooves on the basal half. The two species are best distinguished by voice and range. In flight, the ani alternates between quick, choppy flaps and short glides.
