They also feed on open ground and occasionally on
ledges. Typical roosting and loafing sites are building
roofs and ledges, cooling towers, monuments, bridges,
and signs. Typical feeding sites are parks, squares,
food loading docks, garbage areas, railroad sidings,
food plants, and wherever people eat outdoors.
Male pigeons are sexually mature at three to four
months of age; females at six months. Pigeons usually
mate for life unless separated by death or accident. If
one partner of a mated pair is lost, the survivor will
re-mate within a few days. After pairing and mating,
nest construction begins.
Pigeons nest on a frail platform of small twigs,
straw, and debris in which they make a slight
depression. Nests are usually located in protected
openings in or on buildings and structures. The male
usually selects the nest site but both adults actually
build the nest, with the male often bringing nest
materials to the female.
