This is the Three-Wattled Bell Bird, recorded in Costa Rica, Central America.

Because of the secretive behavior of this bird, it is often only detected by the distinctive bell-like call given by the males. At close range, the vocalization of many in Costa Rica is heard as a complex three-part song, the “bonk” giving the bird its name. This hollow, wooden “bonk” is thought to be among the loudest bird calls on Earth, audible to humans from over 0.5 mi (0.80 km) away. 

Watch a phenomenal amount of videos with birds, including more that either look or sound quite unusual: the common potoo, the red-capped manakin, the not-to-be-missed birds of paradise, and the kookaburra
