Groove-billed Ani is one of several species of medium-sized, black passerines that are common in Central and northern South America. They are found from Texas, USA south to Venezuela, Colombia, and coastal Ecuador and Peru. This species is typically found roving around open areas in groups, eating arthropods and small vertebrates. Groove-billed Anis have fascinating social structure, with groups of up to 5 pairs living together and laying eggs in the same nest. Eggs and young are then cared for by all the contributing birds.
