Data Sheet

Diet: Insectivore

Hildegarde’s tomb bats feed primarily on insects such as moths, grasshoppers and crickets, which they catch in flight or glean off vegetation. 

Fun Fact: Hildegarde’s tomb bat males have a gland on their chest which produces an oily secretion for scent-marking. It leaves a dark stain on their fur, giving the impression of a black beard. 

Appearance: A moderate-sized bat with a body mass between 20 and 36 g, they have light brown fur covering their backs and heads and a white, or lighter, belly. Their wing membranes are white. The tail emerges through the tail membrane on the dorsal side, but is completely enclosed by it during flight. 

Habitat: Hildegarde’s tomb bats roost in groups in coral caves along Kenya’s and Tanzania’s coastline. Their range is very limited and they seem to require specific cave characteristics to persist. Not much is known about their habitat use but they likely forage in undisturbed forests and mangroves along the coastline.  

Conservation Concerns: This species is currently listed as ‘Endangered’ on the IUCN Red List as the population has only been recorded from a limited number of locations and is facing substantial threats to their survival. Cave disturbance and landscape destruction are two main factors impacting the bats.
