The Ecuadorian hummingbird is the bird that can sing and listen to pitches which is beyond the sound rang of any other birds. Sitting on a flowering shrub of a windy Andrean mountainside this tiny Hillstar hummingbird keeps chirping in an ultrasonic sound which is very calming to listen to. The voice has always been compared to a very seductive tone which helps humans to relax and sleep.
Hummingbirds have a very seductive tone and the male and females have specific forms during this entire process. As the male sings they inflate their throats which causes iridescent throat feathers to glisten brightly princely purple. The female joins the male in a courtship dance or chase him off.

Scientists have shown that these hummingbirds can sing as well as hear in pitches that are beyond the range of other common birds. The research has been published in the journal named Science Advances and is available for you to read and analyze. The male ballad sings at around 13.4 kilohertz. The ultrasonic range for birds is generally above 10 kilohertz.
Something interesting goes on with these species of avians which helps them hear such high frequencies of sound. The sound is not too shrill but also not too soft which makes them just perfect for providing a soothing experience to human ears. Christopher Clark, a biologist at the University of California, Riverside says, they confirmed that this song has a social function.
The researchers believe the birds may have evolved to sing at high pitches so that their love songs wouldn’t compete with background noises in their environment, such as mountain winds, streams and the songs of other birds, said Marco Monteros, a study co-author and biologist at Universidad Técnica del Norte in Ibarra, Ecuador.
