Books About Birds: Swifts

The Apodiformes diversified during the Eocene, at the end of which the extant families were present; fossil genera are known from all over temperate Europe, between today's Denmark and France, such as the primitive swift-like Scaniacypselus [5] (Early–Middle Eocene) and the more modern Procypseloides (Late Eocene/Early Oligocene – Early Miocene). A prehistoric genus sometimes assigned to the swifts, Primapus (Early Eocene of England), might also be a more distant ancestor. These are closely related to the treeswifts of the family Hemiprocnidae. There are 4 species of treeswift.

London: Merehurst Press. pp.134–136. ISBN 1-85391-186-0. The family name, Apodidae, is derived from the Greek ἄπους ( ápous), meaning "footless", a reference to the small, weak legs of these most aerial of birds. [2] [3] The tradition of depicting swifts without feet continued into the Middle Ages, as seen in the heraldic martlet. Swifts are among the fastest of birds in level flight, and larger species like the white-throated needletail have been reported travelling at up to 169km/h (105mph). [7] Even the common swift can cruise at a maximum speed of 31 metres per second (112km/h; 70mph). In a single year the common swift can cover at least 200,000km, [8] and in a lifetime, about two million kilometers. [9]
