Falco columbarius (merlin) was observed attacking and feeding on Tadarida brasiliensis (Mexican free-tailed bat) in downtown Abilene, Texas. The number of bats, time of emergence, the number of attacks by merlin, and success of merlin capturing bats were recorded. This study also documents techniques used by bats to avoid predation. To our knowledge, this study documents the first known predation of Mexican free-tailed bat by merlin and is one of the few that shows sustained predation on Mexican free-tailed bat by any species of bird of prey.
