The least bittern's call is a low pitched, quack-like, "coo-coo-coo-coo." The Least bittern is amongst the smallest of the herons, tailored for dwelling in dense marshes. This is perhaps a predator-avoidance behaviour, since its small size makes the bittern vulnerable to many potential predators. Small, discontinuous populations exist from Mexico to Costa Rica and the Caribbean with subspecies extending well into South America. Regional declines have been detected over the last 10 years on survey routes across the Great Lakes basin. The least bittern (Ixobrychus exilis)is the smallest member of the heron family and is one of the most inconspicuous of all marsh birds.
