Native Range: Latin America

Notes: a large-bodied cuculid related to the Gooved-billed and Smooth-billed Ani but larger than either of those two species and with a somewhat longer bill; usually found in small groups of about 5-20 individuals; has the peculiar habit of gathering in small ensembles (such as quartets) and collectively vocalizing a burring sound that resembles the labored starting of a old-fashioned car's engine.
