Columba livia
Rock Pigeon
Family: Columbidae · Class: Aves · Order: Columbiformes
The Rock Pigeon is a medium-sized bird measuring 32 to 37 centimeters (12.6 to 14.6 inches) in length with a wingspan of 64 to 72 centimeters (25 to 28 inches). Adults typically weigh between 300 and 500 grams (10.6 to 17.6 ounces). The species exhibits extensive plumage variation, ranging from blue-gray with two dark wing bars (the ancestral wild type) to checkered, red, or nearly white individuals. The head and neck often display iridescent green and purple hues. All variants possess orange to red eyes and pink to red legs and feet. Originally native to rocky coastal areas and cliffs of Europe, North Africa, and western Asia, Rock Pigeons now inhabit urban and suburban environments worldwide. The species was introduced to North America by European colonists in the early 1600s and is now established throughout California. Populations occur from sea level to mountainous regions, with the highest densities in urban centers including Los Angeles, San Francisco, Sacramento, and San Diego. Rock Pigeons thrive in human-modified environments, particularly urban areas with abundant food sources and nesting sites. The species shows strong preference for buildings, bridges, and other structures that mimic their ancestral cliff habitats. Nesting occurs on ledges, under eaves, on fire escapes, and in other protected locations. The species adapts readily to diverse elevations, from coastal areas to elevations exceeding 2,000 meters (6,562 feet) in mountainous regions. Rock Pigeons are primarily granivorous, feeding on seeds, grains, and bread provided by humans. Their diet also includes fruits, green vegetation, and occasionally invertebrates. The species demonstrates well-developed homing ability and can navigate using magnetic fields, sun position, and landmarks. Breeding occurs year-round in favorable conditions, with peak activity in spring and summer. Females typically lay two white eggs per clutch on a simple platform nest constructed of twigs, debris, and other materials. Incubation lasts 17 to 19 days, with both parents sharing duties. Young fledge after 25 to 35 days but may remain dependent on parents for several additional weeks. The species exhibits strong social behavior, often feeding and roosting in flocks. Flight patterns include rapid, direct flight punctuated by gliding phases. Rock Pigeons produce a characteristic cooing call and engage in elaborate courtship displays involving bowing, tail-spreading, and circular walking patterns. Rock Pigeons hold no special conservation status in California or federally, as they are considered a non-native, introduced species. Populations remain stable to increasing across their introduced range. While some consider them urban pests due to their abundant droppings and potential property damage, others value their adaptability and role in urban ecosystems. Management efforts typically focus on population control in areas where large flocks create conflicts with human activities, rather than conservation measures.
