Prelims level : Bellbirds

Mains level : NA

  • Bellbirds have the loudest bird calls yet documented in the world, according to a study.


  • The study found that their mating songs pack more decibels than the screams of howler monkeys and the bellows of bisons.
  • The male white bellbird’s mating call is about three times louder than screaming phias — the previously loudest bird singer.
  • The bellbird’s calls were so loud that they wondered how the females of the species listened to them at close range without permanent damage to their hearing.
  • The loud singing ability also came with a trade-off, according to the researchers, who said that as the songs of bellbirds became louder, they also got shorter in duration.
