About the Groove-billed Ani

The groove-billed ani (Crotophaga sulcirostris) is a 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, central Mexico and The Bahamas, 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 was formally described by the English naturalist William Swainson from a specimen collected in Temascaltepec, Mexico. It still bears its original binomial name of Crotophaga sulcirostris. The specific epithet combines the Latin sulcus meaning "furrow" with -rostris meaning "-billed". The species is monotypic: no subspecies are recognised.

The groove-billed ani is about 34 cm (13 in) long, and weighs 70–90 g (2.5–3.2 oz). Wingspan ranges 41–46 cm (16–18 in). It is completely black, with a very long tail almost as long as its body. It has a huge bill with lengthwise grooves running the length of the upper mandible. It is very similar to the smooth-billed ani, some specimens of which have bills as small as the... Wikipedia →
