Miscellany: Swainson's Hawk nests and migrates mostly in and through the western half of North America, and almost all of them undertake a more than 6000 mile one way , as measured from the center of their breeding range in the northern prairies, to the center of their wintering grounds in southern South America. Maine has very few records.
