This recording was made at the foot of the mountain next to the houses.
Подробности наблюдения
It is distinguished mainly by the very dark plumage, with the very dark «infra-alar» covers, and by calling shrill. Although it is relatively easy to distinguish from swallows, the Common Swift can easily be confused with its pale-swift congener, which may also appear black in unfavorable light conditions, but this was not the case. This species is one of the last to leave.
