Pigeons and doves are of the order Columbiformes
and the family Columbidae. They are small headed, short-legged,
swift-flying birds with pointed wings and fanned or tapered tails.
Females are duller than males. All species coo. They bob their
heads when walking. They eat grains, small seeds, acorns and
fruit. The nests are generally in trees. On average there are
two white eggs laid.
Ground doves (7 inches), slightly larger
than sparrows, inhabit brush and farmlands in the southern United
States and into Mexico. The tail is short and broad. Their coloration
is brown with rufous in the wings. The feet are yellow. They
usually nest on the ground. The call is a series of low soft
whistles, each with a rising inflection: hooah.
