Male and female Northern Flickers are popularly known as “machine gun woodpeckers” because of the sound they make when hitting their beak on metal, which sounds a lot like the sound of a real machine gun.
The Northern Flicker is a woodpecker native to most of North America, parts of Central America, Cuba, and the Cayman Islands. It is 7 to 15 inches long , with a brown, barred back and black spotted under-parts. From early spring and into midsummer, this bird likes to make its presence felt by making a loud, evenly spaced, rapid drumming sound by hammering their beaks against metallic surfaces. This sound is both a mating call and a way to establish territory, but to the human ear it sounds just like a machinegun, hence the bird’s nickname, machine gun woodpecker.
