The Three-wattled Bellbird (Procnias tricarunculata) is a species of bird native to Central America from western Honduras south to eastern Panama. They are found primarily in the Costa Rican highlands in the breeding season and migrate to lower elevations in the colder months.
This bird is between 9.75 and 12 inches long. The body, tail, and wings of the male are mostly chestnut-brown. The head is white with a black eye ring, eye stripe, and bill. Its name comes from the three worm-like wattles of skin that hang from the base of the bill. The wattles can be as long as 3.9 inches. The female is smaller than the male and is less striking in appearance. The female also has no wattles.
This bird is shy and secretive and is usually only detected by its bell-like call given by the male. The vocalization can be heard as a three-part song with the final “bonk” giving this bird its name. The hollow “bonk” is considered one of the loudest bird calls in the world and can be heard by humans as far away as a half mile.
