They now can be found in most areas of North America, and throughout the world, except in the forests and mountains. A rather flimsy nest of twigs is built on a ledge or recessed area, and one or two eggs are laid. After eighteen days they hatch. The nestlings are fed a regurgitated liquid known as pigeons milk, by both parents. The young pigeons leave the nest in four to six weeks.
Pigeons feed primarily on seed, grain, garbage, greens and insects.
If you have pigeons in your neighborhood make sure there is no access to your attic. This will also keep other unwanted visitors out. If pigeons are investigating a recessed area under your eaves, apply scare tactics or screening immediately before they decide to stay and nest. When pigeons are landing on your roof and you don't want them there, the same principle applies. Do not feed the pigeons.
