The bellbird’s extra-large gape helps it to achieve pneumatic-drill-level volume.

By some measures, the bare-throated bellbird, which lives in the Atlantic Forest of northeastern South America, is even louder than its cousin the white bellbird. Credit: Nick Gordon/Nature Picture Library

Some birds are really quite loud. To find out exactly how loud, João Menezes and Jefferey Podos at the University of Massachusetts, Amherst, recorded the songs and calls of 123 bird species in Massachusetts and the Brazilian states of São Paulo, Mato Grosso do Sul, Rio de Janeiro, Roraima and Amazonas between December 2018 and January 20251.
