During mating season, animals use unique and peculiar mating calls to attract the attention of potential mates. Sperm whales which are famous for being the loudest animal on Earth also use mating calls as seduction tactic but even they cannot compete with the loudest bird in the world, the White Bellbird.

Dubbed as the world’s loudest bird, White Bellbird certainly do not have to worry about getting the message delivered to potential mates.

Just how loud their mating calls are?

According to biologist Dr. Jeff Podos of the University of Massachusetts and lead author of a study on White Bellbirds’ mating songs, the birds’ mating calls are so deafening that it reaches the decibel levels equivalent to a hammering of a pile driver, around 125 decibels.

White Bellbirds have two songs, as reported in the study.

The first song which is commonly produced by the birds can reach up to 117 decibels

Meanwhile, the second song which the male birds produce when there are female birds around can reach up to 125 decibels.

This is also equivalent to standing beside or near a siren which has a decibel of 120.

According to Dr. Podos and his team, it is actually hard to gauge the exact decibels of the bird’s mating songs from different distances.

Nevertheless, they were amused that the male White Bellbirds only produce the mating song when there are female White Bellbirds at a close range while most other animals reserve loud calls for long distances.

They also wondered how the female White Bellbirds are willing to stay close to male White Bellbirds as they belt out the deafening mating song even at the expense of their auditory system

“I am surprised that the loudest bird makes loud sounds when the female is so close,” said Nicole Creanza, an assistant professor at Vanderbilt University told the New York Times.

While other birds will usually tone down their mating calls when a female shows their interest, it does not apply to White Bellbirds. The male birds sing louder when female birds get closer to them.

“The bellbird’s strategy goes against expectations,” Dr. Podos told the New York Times. “They just really seem to be socially awkward.”
