The greater ani is about 48 cm long and weighs 170 g. The adult is mainly blue-glossed black, with a long tail, massive ridged black bill, and a white iris. Immature birds have a dark iris.
Behavior
This is a very gregarious species, always found in noisy groups. The calls include croaking and turkey-like gobbling "kro-koro". The greater ani feeds on large insects and even lizards and frogs.
Habitat
This ani is found in mangrove swamps, semi-open woodland near water, and the edges of forests. It is a seasonal migrant in at least some parts of its range.Reproduction
The nest, built communally by several pairs, is a deep cup lined with leaves and placed usually 2–5 m high in a tree. A number of females lay their chalky deep blue eggs in the nest and then share incubation and feeding. Nests have been found containing 3–10 eggs.References:
