The Black Swift, a species of continental concern in the U.S and Canada, has declined by 94% over the past 60 years.

Black Swifts forage on aerial plankton (tiny lifeforms that drift through the air), however, there is no information on the distance covered from their nest sites or their foraging habitat relationships during their breeding or wintering seasons. By placing GPS tags on birds, we will be able to answer some fundamental movement ecology questions.
