Columbidae is a biological family of birds that includes some 310 species of pigeons and doves. They are stout-bodied birds with short necks, and have short slender bills with a fleshy cere. Like some other birds, Columbidae have no gall bladders. Pigeons and doves feed on seeds, fruits, and plants; they are distributed everywhere on Earth, except for the driest areas of the Sahara Desert, Antarctica and its surrounding islands, and the high Arctic. The largest range of any species is that of the Rock Dove.
