Habitat, diet, life cycle, and behaviors
Pigeons have adapted well to urban environments. Let’s examine their habitat, diet, key behavioral traits, and life cycle.
Where do pigeons live?
Originally found wild in Europe, North Africa, and western Asia, feral pigeons have become established in cities around the world. The lack of adequate sanitation, deliberate feeding of the birds by humans, and "cliff-type" nesting sites on older buildings are the principal factors that attract pigeons to cities.
They can inhabit roofs, ledges, drain spouts, lofts, attics, caves, etc. They also frequent parks and sidewalks, where they become habituated to people feeding them. Pigeons are mainly creatures of habit and tend to feed, nest, and roost in the same place day after day.
Pigeons are a pest in most urban areas in the US. On the West Coast, our local pest control technicians find pigeons affect many of our customers in cities such as Boise, Roseburg, Salinas, Spokane, Novato, and Palm Springs.
Diet
Pigeons eat grains, seeds, and discarded human food like bread or popcorn. They’ve also been known to feed on livestock manure and insects, which shows just how unselective and unsanitary their eating habits are. This diet makes urban areas perfect feeding grounds, and over time, they've become less picky, often feeding from trash bins or handouts from people.
Life cycle
Pigeons pair for life and can live up to 15 years, though in urban environments, their lifespan is often closer to three or four years.
A female pigeon lays one or two eggs per clutch, and both male pigeons and females help incubate the eggs for 17 to 19 days. The baby pigeon, or squab, stays in the nest for four to six weeks and is fed a thick liquid called pigeon milk or crop milk, regurgitated from its parent’s crop - a pouch in their throat. Pigeons can breed year-round, sometimes laying more eggs before the previous brood has left the nest.
