ANIMALS – High-pitched sounds. A species of hummingbird capable of producing the highest pitched sound ever recorded in birds. It was discovered by scientists in Ecuador, as AFP reports. The animal of 14 centimeters is nicknamed “the Ecuadorian little star” and emits a countertenor song that has long been confused with the buzz of insects or the whisper of the wind.

“I heard that sound, but it didn’t even occur to me that it could be the song of a bird. For me, it sounded like the whisper of the wind in the meadow, to an ‘sssss’ ”, recalls Ecuadorian scientist Carlos Rodriguez who studies the evolution of birdsong at the University of Texas, in the USA. Oreotrochilus chimborazo sings at a fundamental frequency of 13,4 kilohertz (kHz), who can go up to 16 kHz, according to a study published in July in the journal Science Advances, while the vast majority of birds emit sounds ranging from 2 at 8 kHz.

This hummingbird has a crown that goes from purple to blue, according to the light, as you can see in the video at the top of this article. These colors and the frequency of his song are the mode of communication he uses "in specific social contexts which are the defense of a territory and the seduction", Fernanda Duque explains to AFP, Ecuadorian neuroscientist from the University of Georgia and author of the article.

Experts have identified that only males can perform this high-pitched song. This unique species is also able to live in extreme conditions, at 5.200 meters above sea level. Ecuador has some 130 hummingbird species.
