Which subspecies of Peregrine Falcon is known to dwell in the Pacific Northwest?

Peale's Peregrine is known to inhabit the Pacific Northwest, specifically in coastal areas of the region. This subspecies is adapted to the diverse habitats found along the coast, including estuaries and maritime cliffs, where it finds abundant prey such as waterfowl and seabirds. The distribution and nesting habits of Peale's Peregrine further affirm its presence in this particular part of the United States, differentiating it from other subspecies that may occupy different geographical areas or ecological niches.

The American Peregrine is found throughout North America but is not specifically associated with the Pacific Northwest region like Peale's. The Tundra Peregrine primarily inhabits tundra regions and migrates south in winter, thus not dwelling year-round in the Pacific Northwest. The European Peregrine also has its own range that primarily covers parts of Europe and Asia, rather than the Pacific Northwest in the United States.
