The Pygmy Swift is a tiny brown-and-white swift with a deeply forked tail. There are two subspecies described within the Pygmy Swift's limited range in northern Venezuela; T. f. furcata and T. f. nigrodorsalis. Mainly found in tropical, lowland, evergreen forest and second-growth scrub, the Pygmy Swift spends most of the day on the wing in search of flying insects. Like the closely related Antillean Palm-swift, the Pygmy Swift is often found using royal palms for nesting and roosting. Despite its restricted range, the Pygmy Swift's population is believed to be stable, and consequently has not been placed on any threatened species lists; however, better study of the population's structure and stability is needed.
