A baby pigeon is called a squab. Pigeons are highly intelligent birds and are among the few species in the world to pass a self-recognition test when placed in front of a mirror. Pigeons are found all over the world with the exception of Antarctica and the Sahara Desert.
Pigeons are omnivorous and have a lifespan ranging between three and five years. Pigeons typically grow to be between 24 and 40 centimeters in length. The most common habitat for the pigeon is coastal regions but feral pigeons have adapted well to urban life over the years. Pigeons and doves comprise roughly 300 species of the order Columbiformes. The term pigeon is often used interchangeably with dove to refer to smaller species.
