A case of snake predation upon bats in northern Morocco: some implications for designing bat grilles

During a study of North African mouse-eared bats in Morocco in August 1993 (Arlettaz et al., 1997) some accidental observations on chiropterophagy by the snake Coluber hippocrepis were made. This adds a new species to the list of bat-eating serpents documented so far (for a general review see Schätti, 1984). In addition, our observations lead to some recommendations for the construction of bat grilles at underground sites to minimize predation risk by snakes or other predators upon bats.
