Latin: Columba livia domestica.

Domestic pigeon

The domestic pigeons roosting on and in buildings are astray descendants of the ordinary pigeons. Like their ancestors, the European rock doves, they prefer to build nests up high on ledges. The pigeons can get by with very little nesting material. A pigeon’s nest is just a cake of excrement, held together by a few straw or sticks. The pigeons can however collect quite a lot material over time when they have the opportunity. The pigeons begin laying eggs in early spring and can get a dozen young during the summer.
