The Egyptian slit-faced bat roosts in colonies, containing anything between a few individuals to a staggering several hundred bats (2). Leaving its roost shortly after nightfall, the Egyptian slit-faced bat commences its hunt for prey, which it detects using echolocation (2). The weak, broad echolocation calls of this species allow it to hunt for prey in cluttered environments (5), and are also the reason for its alternative name of ‘whispering bat’ (8). It mostly feeds on insects, such as beetles, grasshoppers and moths, but has also been reported to eat scorpions (2). The captured prey is taken to regular feeding points, where it is consumed whilst the bat hangs from a temporary perch. The unpalatable parts of prey accumulate below such points, giving scientists a useful indication of this bat’s diet (2) (3) (4).
The breeding season of the Egyptian slit-faced batoccurs between April and July (2), with a single offspring born in early November (2) (9), which feeds on the mother’s milk for around two months (9).
