Brought over to the Americas as domestic birds, pigeons have long since turned feral and now reside in cities, villages, and farms. In the countryside, they rely on crop fields for sustenance while in urban areas, they feed on plant matter, garbage, and insects—not to mention the free meals they get from people in parks!
Pigeons mate for life; if they lose their partner for whatever reason, they quickly find another.
As keen observers of human activity, pigeons love vantage points with smooth, flat surfaces. They are also social creatures, and all members of a given colony share the same space for everyday activities.
