Mockingbirds have a very distinct song that they sing. They are often recognizable right away in the spring and their song seems to become stronger as the summer days get longer. However, mockingbirds don’t just sing during the day. They sing all night as well.
For hours upon hours you can enjoy the song of the mockingbird all summer long if you really want to. But why do mockingbirds sing at night, and why are they singing for so much longer than other birds? Mainly the male mockingbird is attempting to attract a mate. While this is done mostly during the daytime hours, their songs continue throughout the night. Simply put, the mockingbirds are attempting to fend off other suitors. They seem to think that they are in a constant battle with other mockingbirds over their territory as well as their mates. The more threatened a mockingbird feels, the louder their song becomes. So if you are listening at night and hear a mockingbird that seems to be getting louder and more aggressive with their song it’s because they are trying to fight off either a real or imaginary threat with other mockingbirds.
