Why do birds sing?

Birds sing for several reasons, primarily for communication and mating purposes. Male birds often sing to establish and defend their territory, warning other males to stay away. Singing is also an important part of attracting mates, as a strong, varied song can signal good health and genetic quality. In addition, some bird species sing to communicate with other members of their flock or to express different emotions, such as hunger or distress. Singing is an essential part of a bird’s behavior and plays a significant role in reproduction and survival.
