Suited to the food so-called air plankton - a very small flying insects, and therefore have a short beak and a wide section of the mouth. Legs are very small, so that Swift could not take off from the ground. If the bird is still on the ground, it has to crawl to the nearest wall or tree to take off again. But in the air Swift did not have at unrivaled speed and endurance, as the flight doing in almost all his life.

Nest under the roof of crack rocks and hollows. The material to the nest - fluff and feathers - are collected in the air, sleep and mate also on the fly. To see the lighting-fast pairing swift flying is not difficult - it is necessary only for a while watch gaggle of birds in late May - early June. But sleeping swift had seen little.
