Where is the Peregrine Falcon found?

This species has 18 recognized races and is found on all continents except Antarctica.  Peregrines are migratory, except in urban areas that have abundant prey, such as pigeons and starlings, throughout the winter. In North America, they live in open landscapes and traditionally nest on ledges on high cliffs where they are free from predators.  Nest sites in natural settings are called eyries.  In urban settings, the birds will nest on skyscrapers or bridges which simulate high cliffs.
