At 125 decibels, his short but startling songs are louder than a jackhammer."The white bellbird may be the loudest bird in the world. These birds are making extraordinarily loud noises. Noises that are so loud, they would be harmful to our hearing if you had to hear them up close."Mario Cohn-Haft, curator of birds at Instituto Nacional de Pesquisas da Amazônia.
