But the beauty of birds isn't just their looks — it's also their noises. Bird songs are among nature's most distinctive and musically satisfying sounds. Why do birds spend so much time and energy singing?
There are two main purposes, and they are connected. First, male birds sing to mark territories. A singing bird is saying, "This place is mine, and I'm willing to defend it, especially from others of my species." He may patrol his chosen space and sing often, either from the middle or the edges of what he considers his turf.
