Resumen:
We report the first prey species consumed by the free-ranging Van
Gelder's bat Bauerus dubiaquercus. We trapped four pregnant individuals
of this species carrying freshly captured dung beetles. We describe the
wing morphology and flight descriptors (wing loading and wing aspect
ratio) of the species, which presents wings more suitable for capturing
insects by aerial hawking, although the evidence suggests that is able
to capture dung beetles of nearly 10% of its body mass in flight close
to the ground. The species could obtain their prey while foraging on
uncluttered pasture near forest edges.
