The domestic pigeon, Columba livia, is probably descended from the rock dove, which nests and
roosts on and in rock formations such as cliffs, gorges and caves. Feral pigeons living in towns are
escaped domesticated birds, and they use ledges on structures made by humans in the same way
that rock doves use natural rock formations. Free-living, feral birds can occur in numbers ranging
from pairs up to large, loose flocks that feed and roost together. However, the pigeon is highly
territorial and will defend roosting spaces and nesting areas. Pairs are usually monogamous and
males „drive‟ females away from the rest of the flock during the breeding season.
Domestic pigeons are primarily seed eaters but will take a wide range of grains, fruits, berries and
vegetation and invertebrates such as small snails. There are over 200 breeds of pigeon in which
different traits have been selected for racing or showing, some of which have traits that could result
in welfare problems. It is important to bear this in mind when choosing a breed for laboratory use.
