City pigeon

Feral pigeons (Columba livia), also called city doves, city pigeons, or street pigeons, are derived from domestic pigeons that have returned to the wild.[1] The domestic pigeon was originally bred from the wild Rock Dove, which naturally inhabits sea-cliffs and mountains.[2] Rock (i.e. 'wild'), domestic and feral pigeons are all the same species and will readily interbreed. Feral pigeons find the ledges of buildings to be a substitute for sea cliffs, have become adapted to urban life, and are abundant in towns and cities throughout much of the world.[3]
