However, the more we study birds, the more complicated the story gets. It’s pretty well understood that when a male bird sings, he’s simultaneously trying to impress his mate while also sending a message to nearby males saying “stay away!”. Since males typically know about eight songs at most and each song lasts a few minutes, the entire performance takes about half an hour.ĭawn chorus has been studied extensively–this glorious cacophony is what leads many people to become birders. ![]() Like the primo uomo playing the starring role in an opera, males perch beside their nest and sing as loud as they can, waking up their female mates to a dramatic serenade that includes every song they know. ![]() During springtime, males of this species awaken at first light determined to do one thing: sing their hearts out.

The singing behavior also helps them to attract a mate for nesting, so singing is most intense during the spring. Males do the most singing, with the primary function being to establish and defend their feeding and nesting territories. While adding to the atmosphere of the backyard, the singing behavior also helps birdwatchers locate birds that may otherwise go unnoticed. Some birds that only migrate through mid-Missouri may sing as they travel too. In April and May, returning breeders add to the chorus. ![]() Resident birds start singing in Feb and March.
