Scientists Identify Two of the World’s Noisiest Birds – and They’re 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, advancing their quest to understand how evolution shapes bird communication.
- Podos previously measured a white bellbird call at 125 decibels, prompting him and Menezes to investigate why some birds are significantly louder than others across the 123 species they 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 the researchers' initial evolutionary theories.
- Derryberry, who directs Cornell's Macaulay Library of Natural Sounds, praised the work for filling "a pretty large gap in knowledge," while Senner, an assistant professor of Environmental Conservation at Umass Amherst, emphasized understanding avian evolution is critical for conservation.
- Podos stated the team is "not actually super interested in the race to say which is the loudest bird," instead aiming to track how avian communication evolves and predict how species might adapt to changing environments.

Scientists identify two of the world’s noisiest birds – and they’re as loud as a jackhammer
By Amarachi Orie, CNN (CNN) — There are two new contenders for the world’s loudest bird – and scientists are not being quiet about it.Researchers at the University of Massachusetts Amherst found that the bare-throated bellbird and the red-legged seriema both create songs at amplitudes above 120 decibels, according to a study published Tuesday in
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 …
