Why birds sing




















The species that sing create musical sounds by their syrinx. This is a kind of double voice box at the bottom of the windpipe. Two sets of membranes and muscles where the windpipe branches into the lungs vibrate at high frequencies as air is exhaled. In fact, while singing, a bird can alternate exhaling between its two lungs and thereby sing in harmony with itself. Usually a male that is defending a territory or attracting a mate will sing from one of the highest or most conspicuous spots available.

This favorite spot may be used time and time again. On the other hand, some birds, such as larks, bobolinks and buntings, sing while flying. And while birds usually do not sing around their nests, a few sing a quiet "whisper song" that can be heard for only a few yards.

In the final analysis, different birds sing different songs but usually for much the same reasons. One of those just might be that they are well fed, stress free and happy. Check Out These Magazines!

One idea is that in the early morning, light levels are too dim for birds to do much foraging.

Since light levels don't affect social interactions as much, it's a great opportunity to sing, instead. Another idea is that early morning singing signals to other birds about the strength and vitality of the singer.

Singing is an essential part of bird life, but it's costly in terms of time and energy. Singing loud and proud first thing in the morning tells everyone within hearing distance that you were strong and healthy enough to survive the night. This is attractive to potential mates, and lets your competitors know you're still around and in charge of your territory. For many years, scientists theorized that the atmospheric conditions in the early morning — typically cooler and drier than later in the day — might allow birdsong to travel further through the air.
