Wikipedia Abstract

The boat-billed heron (Cochlearius cochlearius), colloquially known as the boatbill, is an atypical member of the heron family, and was formerly thought to be in a monotypic family, Cochlearidae. It lives in mangrove swamps from Mexico south to Peru and Brazil. It is a nocturnal bird, and breeds semi-colonially in mangrove trees, laying 2–4 bluish white eggs in a twig nest.
