What is Birdsong

Thursday - May 10, 2018 1:17 pm , Category : Fun Facts

May 10 (WTN) - Birdsong is an exceedingly complex and sophisticated communication system. It is produced from the bird’s syrinx, a sound box at the junction of the two bronchi, which lead to the lungs. Air from the lungs is passed over membranes in the syrinx, which then vibrate ,producing sound waves. Because there are two bronchi with membranes , sound can emanate from each and combing higher in the vocal tract, producing a large variety of sounds.

Complexity in the vocal muscles also translates in to more complex song. Birds sing to defend territory and to attract mates. Some species even sing when pursued by predators to convey how robust they are. On the whole, males sing more than females. The male brown thrasher has command of some 2000 difference songs. Male and female birds sometimes sing duets and groups of birds may sing together to defend a territory.

Some species are especially adept at mimicry. Some Scottish starlings reproduces the sounds of sheep some English starlings even mimic city buses.
