The Pacific Swift (Apus pacificus), or Fork-tailed Swift, is a small bird, superficially similar to a House Martin. It is, however, completely unrelated to those passerine species, since swifts are in the order Apodiformes. The resemblances between the groups are due to convergent evolution reflecting similar life styles.These birds have very short legs which they use only for clinging to vertical surfaces. The scientific name comes from the Greek ¿¿¿¿¿, apous, meaning "without feet". They never settle voluntarily on the ground. Pacific Swifts spend most of their lives in the air, living on the insects they catch in their beaks.
