Status and Distribution
The rock pigeon was introduced from Europe by early settlers; it is now widespread and common throughout the United States and southern Canada, particularly in urban settings. Gregarious and forming large flocks, it feeds on handouts and grains during the day in city parks and open fields; roosts on buildings at night. Flocks or otherwise displaced pigeons can be found far from civilization. Breeding: nest is loosely constructed of twigs and leaves, primarily on structures such as window ledges, bridges, and in barns; has 2 white eggs.
Primarily associated with human development and dependent on people for food and shelter.
