Anatomy: The Rock Dove is from 12 to 14 inches (30 to 35 cm) long. Its coloration is extremely variable.

Diet: Pigeons eat mostly seeds. Pigeons drink by sucking up water (very few other birds do this).

Nest and Eggs: Male pigeons build shallow, saucer-like nests made of sticks and twigs. Nests are usually located on ledges, like seaside cliffs or window sills on skyscrapers. Females lay 1-2 white eggs in each clutch (a set of eggs laid at one time). Both parents incubate the eggs.
