Birds make all sorts of interesting sounds. Some have beautiful melodies other have obnoxious squawks.
There are reasons for these sounds. Birds use these songs and calls to communicate with other birds. The reasons can even be very complex.
A few species, like turkey vultures, are almost always silent. Most birds though are chatterboxes and have several different calls.
Birds that live in flocks most of the year are especially busy with several different calls.
Black capped chickadees have at least 15 different distinct calls that they use for various situations. If their flock is foraging in treetops, they make short light “contact” calls and a louder note when the flock is ready to move on. Chickadees make various alarm calls when danger is near. Rival males have aggressive calls they use when they are about to have a showdown.
