This falcon species is large and stocky with pointed wings and short tail. The peregrine has a dark head, uniformly patterned underwing, and gray or dark barring on belly. The fastest diving bird, the peregrine dives on smaller birds at speeds of up to 200 miles per hour. Although no longer listed as an endangered species, the peregrine falcon is now considered threatened.

Coho salmon range along both sides of the North Pacific Ocean and are the backbone of the Alaskan troll fishery.  It is also one of the most popular sport fish in the Pacific Northwest.  The dramatic declines of salmonid, including Coho, populations in the past several decades have apparently resulted from a complex interplay of factors that include, significantly, loss of habitat.  For this reason, the restoration of the Nisqually estuary has been recognized as an important step forward in Coho Salmon conservation efforts.
