Why do birds sing?

 Because there are so many different species and types of birds, there are few hard and fast rules about why birds sing, but we can make some generalizations about why birds sing that hold true for the vast majority of cases. They sing or call to attract a mate, to find their existing mate, to defend their territory, to sound an alarm, to signal the availability of food, or in the case of baby birds, to ask for food.

Each of these different bird song motivations calls for a different song. Every different bird species also sings a song that is very distinct from those of other bird species. Scientists and experienced birders can even detect regional dialects in the songs of birds of the same species from different regions. With the information in the rest of this series, a beginning birdwatcher will be better able to understand bird behavior and figure out why a bird is singing when they hear a birdsong.

This series is broken out into separate pages for each type of behavior for your convenience . Click each link below for detailed information about why birds sing.
