        Well, there are the flying foxes...
        Although this might explain why bats have thrived in the face of
bird competition, unlike what appears to happen in the late Cretaceous
with pterosaurs. Pterosaurs probably competed more with the birds for
niches than modern, nocturnal bats do, since they were probably diurnal
as a group.
