The Washington Gap Analysis Project created breeding bird maps only. The non-breeding birds (e.g., wintering, pelagic (coastal), and birds expanding their ranges) are represented only by NatureMapping sightings.
NatureMapping observations reported by townships throughout the year.
The Rough-legged Hawk is found in Washington only during winter. This hawk of open country migrates in large, loose flocks, wintering all across southern Canada and the entire United States except for the south-east. In the west, it nests in the Aleutian Islands and in Alaska.Text edited by Gussie Litwer
