. The birds of Britain : their distribution and habits . Birds. 100 Order II and presumably in origin, becoming similar to one another for all practical purposes. Apart from acci- dental visitors, we have only in Britain one member of the family, the black Swift or Deviling {Micropus apus), which arrives a little later than the Swallows, charms us by its aerial evolutions, startles us by its piercing screams, and disappears very regularly by September. It is peculiarly a denizen of the air, which. Swift on nest rises from the ground with difficulty, and, having aU its toes pointing forward, can hardly be said to perch. The food consists of insects taken on the wing, as the birds circle widely in the air, singly or in small parties ; the flight is most characteristic, a number of quick vibrations of the wings being followed by periods of inactivity, when the bird ghdes with motionless wings held in the shape of a bow. Swifts generally breed in small colonies under the eaves of houses, but they also make use of crevices in cliffs and quarries, as well.
