Breeding males are mostly black and white. As with other migrants, these route differences, coupled with differences in biotic and abiotic factors between seasons, mean that a full understanding of the annual life cycles requires studies of both migratory seasons. Blackpoll warblers that breed in western North America may migrate up to 12,400 miles roundtrip each year, some crossing the entire North American continent before making a nonstop trans-ocean flight of up to four days to South America. Studies of fall migration in this species have centered on the extensive overwater flights but have ignored other aspects of this migration, including potential geographic variation.
