The American black swift or more simply black swift (Cypseloides niger), is a species of swift that are found from northern British Columbia in Canada through the United States and Mexico to Costa Rica and Brazil. They are also found on islands in the West Indies. In flight, these birds resemble a flying cigar with long slender curved wings. The plumage is mostly a sooty dark gray. There is some contrast between the upper and lower wing. The shoulders are much darker in color than the remaining portion of the wing. They also have short slightly forked tails.
