Bald eagles were nearly extinct in New York City due to environmental factors such as pollution and pesticides. Michael George spoke to an urban park ranger sergeant who participated in the two-decade effort to bring the birds back to the city.
The bald eagle is a bird of prey found in North America. A sea eagle, it has two known subspecies and forms a species pair with the white-tailed eagle, which occupies the same niche as the bald eagle in the Palearctic.
