dc.description.abstract
The exploitation of information is a key adaptive behavior of social animals,
and many animals produce costly signals to communicate with conspecifics. In
contrast, bats produce ultrasound for auto-communication, i.e., they emit
ultrasound calls and behave in response to the received echo. However,
ultrasound echolocation calls produced by non-flying bats looking for food are
energetically costly. Thus, if they are produced in a non-foraging or
navigational context this indicates an energetic investment, which must be
motivated by something. We quantified the costs of the production of such
calls, in stationary, non-foraging lesser bulldog bats (Noctilio albiventris)
and found metabolic rates to increase by 0.021 ± 0.001 J/pulse (mean ±
standard error). From this, we estimated the metabolic rates of N. albiventris
when responding with ultrasound echolocation calls to playbacks of
echolocation calls from familiar and unfamiliar conspecific as well as
heterospecific bats. Lesser bulldog bats adjusted their energetic investment
to the social information contained in the presented playback. Our results are
consistent with the hypothesis that in addition to orientation and foraging,
ultrasound calls in bats may also have function for active communication.
