RESUMO
BACKGROUND: Myotis occurs from tropical to temperate regions throughout the globe, and it is the largest bat genus with more than 100 species. Most species are insect-eaters, but a few also feed on other invertebrates and fishes; there is no confirmed evidence of a plant item in their diet. NEW INFORMATION: During fieldwork in the Brazilian Atlantic Forest, small seeds were retrieved from the feces of one adult female of the Black Myotis, Myotis nigricans-one of the most common Neotropical bats. In a germination experiment, 40% of those seeds grew into seedlings. Our findings are the first evidence of fruit consumption for any Myotis species. We reject a possible contamination because the cotton bag was never used before for bats. This study is the first evidence of frugivory in the genus Myotis.
