Which subspecies of Peregrine Falcon is typically found on the American northwest coast?

Peale's Falcon is the subspecies of Peregrine Falcon that is typically found along the American northwest coast. This subspecies is adapted to the coastal environments of the Pacific Northwest, where it can thrive in habitats that include cliffs and coastal areas that provide ample hunting opportunities.

Peale's Falcon is known for its dark plumage and robust size compared to other Peregrine subspecies, making it well-suited for the unique ecological conditions of this region. Its reliance on coastal food sources, such as seabirds and shorebirds, further cements its place as a characteristic predator of the area, allowing it to effectively hunt within its specific habitat.

The other choices do not belong to the Peregrine Falcon or are not typically associated with the American northwest coast, which reinforces Peale's Falcon as the most appropriate answer for this question.
