Pallid Swift

The Pallid Swift (Apus pallidus) is a small bird, superficially similar to a Barn Swallow or House Martin. It is, however, completely unrelated to those passerine species, since the swifts are in the order Apodiformes. The resemblances between the groups are due to convergent evolution reflecting similar life styles. Swifts have very short legs which they use only for clinging to vertical surfaces.
