The familiar city pigeon — descended from cliff-dwelling Eurasian wild rock doves. Introduced to North America in the 1600s. Highly variable plumage (white, brown, black, multicolored).
§ Quick facts
§ Encyclopedia
The rock dove, also known as the common pigeon or rock pigeon, is a member of the bird family Columbidae. In common usage, it is often simply referred to as the "pigeon", although the rock dove is the wild form of the bird; the pigeons familiar to most people are the domesticated forms of the wild rock dove.

§ Identification
Field marks. Familiar plump city pigeon. Wild type: gray body with two black wing bars and iridescent green-purple neck. Highly variable: white, black, rust, checker patterns all common in feral populations.
Similar species. Band-tailed Pigeon (more uniform gray, white neck band). Mourning Dove (much smaller and slenderer).
Voice. Soft cooing "coo-roo-coo."
§ Diet & behavior
Diet. Seeds, grains, fruits, human food scraps; in cities, anything edible.
Behavior. Domesticated from wild Rock Doves (cliff-nesting pigeons of southern Europe, North Africa, and Asia) over 5,000 years ago. Brought to North America by colonists in the 1600s. Selectively bred for hundreds of "fancy" varieties; many escapees have produced the highly variable urban populations. Famous as the first species used to demonstrate magnetic navigation: pigeons trained to home from distant sites maintain accuracy through 1000+ km journeys, using a combination of magnetic, solar, and visual cues. Also among the first species shown to recognize themselves in a mirror.
§ Range
Cities and suburbs across North America
§ Habitat
Urban areas, cliffs, agricultural buildings
§ Threats
Anti-pigeon control programs, lead poisoning from urban contamination, raptors learning to hunt urban pigeons.
§ Conservation status
According to the IUCN Red List, the rock pigeon is currently classified as Least Concern.
§ What helps
Don't use poisoned bait. Support humane population control. Don't feed (creates flocks that cause conflicts).
