Boat-billed Heron

Boat-billed Herons inhabit swamps from the coasts of central Mexico south through most of the Amazon Basin. Because they tend to feed at night—note the large eyes—these herons can be illusive. They use their out-sized bill to scoop up prey—fish, crustaceans, insects and amphibians. The herons walk along with their bills half submerged in the water. The bill is thrust forward when prey is encountered (Handbook of Birds of the World). We saw several during our Tarcoles, Costa Rica, mangrove swamp tour on 4 July 2017.
