 The Pacific swift has a very large range, exceeding 10,000,000 km2 (3,800,000 mi2). Its population is unknown, although it is common throughout its breeding range with no evidence of any decline. It is therefore classified by the International Union for Conservation of Nature as being of least concern. There appear to be no significant threats to this bird; predation is low, and this swift is not tied to a particular habitat. Some birds may die through misadventure or become exhausted when lost on migration (the first record for the Western Palaearctic was found resting on a North Sea gas platform), but swifts have high survival rates and are generally long-lived. The common swift, a close relative of the Pacific swift, has been recorded as reaching 21 years old.
