A research team found the loudest crying bird in the world.

On Monday, foreign sources, including ABC News, reported on the findings of the University of Massachusetts Amherst campus and the Brazilian National Amazon Research Team.

The researchers recently found that the white-crowned rattlesnake in the Brazilian rainforest is 125 ㏈, the largest of the birds. This is larger than the rock concert hall, which is about 110㏈.
The most interesting fact was that the male bellbird was crying so loudly. Is to woo the female.

The sound of the male is loud enough to affect hearing, but the courted female is said to protect the male without concern.

In this regard, the research team said, "It seems that the females are making a noise to assess the males at hand," he said. "We plan to study more about how the sounds of males work for females."
