In situ novel environment assay reveals acoustic exploration as a repeatable behavioral response in migratory bats

Abstract Integrating information on species-specific sensory perception with spatial activity provides a high-resolution understanding of how animals explore environments, yet frequently used exploration assays commonly ignore sensory acquisition as a measure for exploration. Echolocation is an acti...
