Peale's peregrines are large dark birds that nest on the coast of Alaska and British Columbia.

Falco peregrinus pealei, or Peale’s peregrine, named for Titian R. Peale, an early 19^th century Philadelphia artist, is found mostly along the Northwest coast of the United States, the western coast of Canada, the Aleutians and the Bering Sea. This maritime species is mostly resident or only slightly migratory and was not as severely affected by man-made chemicals.
