A striking large species (forearm length almost 60 mm), shown in the photograph at the top of the site's bat pages. The common free-tailed bat is among the most widespread of Israel's bats, and colonies of free-tailed bats are known in the centers of cities in the country. As another crevice-dweller, it has not been severely affected by cave fumigation activity and is found in most parts of the country.

Despite its relative abundance, information about it in the country is scant. Analysis of droppings collected in colonies of free-tailed bats in the south, center, and north of the country indicates that moths make up most of its diet. In Israel, females with pups were observed during the month of June, and it appears that in the colonies studied, most births occur in the first half of the month.

Free-tailed bats are active throughout the year, even on cold nights. This is the only insectivorous bat species in Israel whose hunting calls are clearly heard from a great distance, even without a detector.

Calls: 14-17 (11-60) kh
