A new bat record for Laguna de Apoyo: Pteronotus personatus

We have been studying the bats of Laguna de Apoyo Nature Reserve a while. Three volunteers, Michael Persicke, Lukas Betthaeusen, and Florian Schmid, all have made great contributions to our knowledge of the bats of our area during their volunteer periods sponsored by GIZ. We have 27 bat species on our list, about a quarter of all the species documented in Nicaragua, among the more than 600 bats captured in our studies to date. Nonetheless, there is always something new and special out there. 

Our technician Elmer Nicaragua noticed a small bat hanging from the roof of our patio, and we quickly concluded it was not any of the species we know to be in Laguna de Apoyo Nature Reserve. Elmer captured it with a butterfly net, and we examined it.

The tiny bat was quickly identified by its distinctive face, long wings, and lack of a wing-sac which some species have. The face was distinctive, with a large flap on the chin. And, of course, hair over the upper lip, hence the name Wagner's Mustached Bat.

Wagner's Mustached Bat consumes insects, and uses Doppler shifts in echolocation. This bat species is not well-known in Nicaragua, and this was our first record of it in Laguna de Apoyo Nature Reserve.

We are not surprised at this finding, because we are sure there are many more species of bats in Laguna de Apoyo Nature Reserve than the 27 documented species to date. Our presence here in the reserve, however, and the careful eye of Elmer Nicaragua, allowed us to make this new species record, thanks to his careful, trained eye.

This bat supposedly roosts in warm caves, but it is likely that this individual just got lost and chose our roof for his rest during the day. He is one more example of the importance of Laguna de Apoyo Nature Reserve to the wildlife of Nicaragua.
