The world’s loudest birds squawk as loud as a jackhammer
Researchers measured bird-call volume in 123 species and found a 58-decibel range, including calls above 120 decibels.
- On Tuesday, UMass Amherst biologist Jeff Podos and his former graduate student João Menezes published a study in Evolution measuring amplitude across 123 bird species to understand how evolution shapes communication.
- Podos previously measured a white bellbird call at 125 decibels in 2019, prompting investigation into why some birds are significantly louder than others across the 123 species studied.
- The team identified two additional birds breaking 120 decibels: the bare-throated bellbird and red-legged seriema, both sharing wide beak openings and bulky muscles, though the seriema's open-habitat lifestyle confounded previous theories.
- Derryberry, who directs Cornell's Macaulay Library, said the research fills "a pretty large gap in knowledge," while Senner, an assistant professor of Environmental Conservation at Umass Amherst, emphasized understanding bird evolution for conservation.
- Podos stated "we're not actually super interested in the race to say which is the loudest bird," instead aiming to track how avian communication evolves as environments change.

Two species of Brazilian birds are among the loudest in the world: the bare-gargant arapon and the seriesma. The corners of the two have exceeded 120 decibels of peak, volume higher than that of a chainsaw or a british. The discovery was made by researchers from the University of Massachusetts Amherst, in the United States – among them, the Brazilian and graduate student of the university, João Menezes. The study was published in the scientific …

UMass biologists discover what may be the world's loudest birds
Biologists at the University of Massachusetts Amherst have discovered what may be the world’s loudest birds. There are now three contenders for the Noisiest Bird Award, all living in Brazil. But exactly why these birds are so loud remains a mystery.
