White bellbirds have the loudest mating call, according to scientists who compared the songs of bellbirds and screaming pihas in the Brazilian Amazon.

But the white bellbird blasts an obnoxious “song” so loud that it sounds almost digital. Now, researchers have measured just how ear-splitting it is – and crowned it the loudest bird call ...

The white bellbird only sings its loudest song when a potential partner is nearby. Researchers say its the loudest bird call ever recorded.

The white bellbird’s second song type is louder than a jackhammer, and approaches, “at its peak, the amplitude of a pile driver” — around 125 decibels, said Podos.
