Abstract Bats rely heavily on auditory perception for critical behaviors including navigation (echolocation) and conspecific communication. However, there is little information the impacts of age sex bat system. Here, we used brainstem response recordings to measure thresholds in Carollia perspicillata (Seba’s short-tailed bat). We did not detect an age-related threshold shift at range examined (1-8 years old), suggesting that bats may be relatively resistant hearing loss. had considerably more young (aged 1-2 years) than older animals 4-8 so our results should interpreted with caution. they are consistent other studies showing exhibit fewer signs aging relative small mammals.

Doppler shift compensation (DSC) is a unique feature observed in certain species of echolocating bats and hypothesized to be an adaptation detecting fluttering insects. However, current research on DSC has primarily focused that are not engaged foraging activities. In this study, we investigated the performance Pratt's roundleaf bat, Hipposideros pratti, which was trained pursue insects various motion states within laboratory setting. Our study yielded three main results. First, H. pratti demonstrated highly precise during insect pursuit, aligning with previous findings other flutter-detecting foragers orientation or landing tasks. Second, found state prey had little effect pratti. Third, variations throughout course pursuit. The exhibited highest phase maximum flight speed but decreased capture. These high precision overall time-dependent pursuit support hypothesis
