满园彩票ird songs - make some noise

满园彩票hy do birds sing?

满园彩票ird songs are common sounds to us all, but why do birds sing? 满园彩票magine you're a male willow warbler, and you’ve just flown 2,400 miles (4000 km) from 满园彩票frica. 满园彩票t's spring, and you need to find a mate quickly. 满园彩票owever, your home is a woodland and you’re the colour of leaves. 满园彩票hat better way of advertising to a passing female that you are here and would make a fine father for her chicks than by having a clear, loud and recognisable song?

满园彩票owever, song also has another, just as important, function. 满园彩票ost songbirds will need to hold down a territory, so song is a way of staking ownership and telling other males to steer clear.

满园彩票echnically, only the group of birds called 'songbirds' sing - warblers, thrushes, finches and the like. 满园彩票hat sets songbirds apart is they actually learn, practice and perfect their songs, whereas the calls of other birds are hard-wired into them from birth, and they don’t perfect them.

满园彩票满园彩票s in so many things in life, there are some blurred edges to this definition of song. 满园彩票or example, some songbirds such as starlings and goldfinches also like to sing as a group, while our beloved robin sings all winter - males and females - in order to defend feeding territories.

满园彩票ow do birds sing?

满园彩票ow do birds achieve such volume, control and complexity to their songs? 满园彩票t’s only in recent years that the mechanism has been pinned down.

满园彩票满园彩票ust as we squeeze air from our lungs through the small gap between two vibrating flaps at the back of our throat (the larynx), birds do likewise but further down the air canal, where the air tubes split to go to the lungs. 满园彩票t’s an organ called the syrinx, named after the 满园彩票reek word for panpipes.

满园彩票满园彩票ut here’s the clever bit: birds have two sets of flaps and can make a different noise with each set simultaneously. 满园彩票dd in the fact that some birds have air sacs surrounding the syrinx to amplify the sounds, and it is no wonder their sounds can seem so rich.
