A common sight in urban areas throughout the world, the Rock Pigeon was introduced into North America in the early 1600s. City buildings and their window ledges mimic the rocky cliffs used by wild pigeons.

Cool Facts


Because of their domestic roots, and because people have bred pigeons for many different colors and adornments, feral Rock Pigeons can have a variety of plumages. For a description of the most common varieties, as described for PigeonWatch, go here.


The Rock Pigeon makes a flimsy nest, but it often reuses the location repeatedly, building a new nest on top of the first. Because the pigeons do not try to remove the feces of their nestlings, the nest turns into a sturdy, potlike mound that gets larger month by month. Unhatched eggs and mummies of dead nestlings may also get cemented into the nest.


The Rock Pigeon has such a long history of association with humans, having been used for food and entertainment for over 5,000 years, that the original range of the species is impossible to determine. Escaped (feral) pigeons from pigeon breeders readily form flocks, and wild birds may join them.


Homing pigeons, domestic Rock Pigeons, are well known for their ability to find their way home from long distances. Despite these demonstrated abilities, wild Rock Pigeons are rather sedentary and rarely leave their local areas.
