The Alpine Swift, like other swifts, spends almost all its time in the air. It is specifically adapted to flight, with a compact body and long, narrow, pointed wings. It has a small slightly curved triangular bill, and a large gape that allows it to catch insects in flight. Its tail is short and forked. Plumage is brownish-grey, with a white belly and throat, separated by a brown neckband. Its characteristic flight includes rapid deep wingbeats followed by glides. When foraging, it performs rapid maneuvers, while sounding a series of sharp calls. The Alpine Swift is a gregarious bird that nests in colonies and flies in flocks in its wintering areas as well.
The Alpine Swift is a common passage migrant, a relatively common summer breeder and a rare winter visitor. During migration, flocks can be seen throughout Israel. It breeds in most of the mountainous regions in Israel, from the upper Galilee in the north to the Judean Desert canyons and Negev Highlands in the south.
The Alpine Swift breeds in colonies in mountainous and cliff areas. The nests are often located in crevices and on the ceilings of large caves. In Europe it also nests in tall buildings, similar to the Common Swift, while in Israel it can also be found nesting under tall bridges and in road tunnels.

Occupancy 1990-2020
The map shows differences in the species breeding distribution between the 1980's breeding map and the current weighted breeding evaluation. Negative value - species previously bred in the grid and is not presently breeding; positive value - species has not previously bred in the grid and is currently breeding.

Change in Relative Abundance 1990-2020
The map shows the changes in the relative abundance of a species in each of the distribution grids between the breeding map of the 1980s and the weighted current breeding evaluation. Negative values - decline in abundance; positive values - increase in abundance; zero - no change in abundance.
