• Black Swifts are recognized by their black plumage, streamlined body and long, curved and pointy wings.
  • Black Swifts are present in Banff National Park from late spring until fall. They may be seen singly or in small flocks, flying in and out of canyons or foraging high above for flying insects.
  • Black Swifts nest in canyons often near or behind waterfalls. Each year they lay a single egg in a mossy nest in shallow pockets or ledges along cliff walls.
  • Both parents care for and feed the chick, until it is ready to fly which may take up to 49 days.

 Black Swifts are an endangered species in Canada.

Black Swift populations have declined by over 50% in the last 40 years. The cause(s) for their population decline are not fully understood, however, it may be related to changes in the availability of their food supply as they specialize on a diet of flying insects.

Canada hosts 80% of the North American population with only 0.1% found in Alberta. In 2019, the Black Swift was designated as an Endangered species under Canada’s Species at Risk Act.
