Habitat & Breeding
Found worldwide, the feral or town pigeon is closely associated with humans and is a common sight in urban environments. It may, however, be found in more rural situations, e.g. associated with farms. Feral pigeons build their nests in or on buildings and other structures, where they are usually found on ledges or in hollows often under eaves or on girders. Grass, twigs, feathers or any scraps, such as plastic and wire, may be used in the construction of nests, which are frequently rather flimsily built but, when used for successive broods, may become well defined structures. Since some feral pigeons are capable of breeding throughout the year, nests may be found in any month, however, the peak occurs between March and July. Usually, two white eggs are laid on consecutive days. A new clutch can be laid when the first young are 20 days old. Thus up to nine broods may be produced annually. Feral pigeons normally feed in flocks and for most of the year rely mainly on spillage at food premises or on scraps, including bread, cake grain and "birdseed", given by the public. In some localities birds may fly to nearby arable farmland during spring and autumn to feed on sowings and stubbles. Loading and unloading of grain, at places such as docks and mills, provides a source of food from abundant spillage that normally occurs.
