Differences in body size, echolocation call frequency, and location may result in diet partitioning among bat species. Comparisons among island populations are one way to evaluate these competing hypotheses. We conducted a species-level diet analysis of three Rhinolophus and one Hipposideros species on the Philippine islands of Cebu, Bohol, and Siquijor. We identified 655 prey (MOTUs) in the guano from 77 individual bats. There was a high degree of overlap among species’ diets despite differences...
