The Pacific Flyway is a major north-south flyway for migratory birds in the Americas, extending from Alaska to Patagonia. [1] Every year, migratory birds travel some or all of this distance both in spring and in fall, following food sources, heading to breeding grounds, or travelling to overwintering sites.

Any given bird species travels roughly the same route every year, at almost the same time. Ornithologists and birdwatchers can often predict to the day when a particular species will show up in their area.
