THESE ARE SOME PICTURES OF BATS THAT I TOOK ON A TROPICAL ECOLOGY COURSE OFFERED THROUGH UNIVERSITY OF ALASKA FAIRBANKS. THE THUMB IN MOST OF THEM IS PROBABLY EITHER JOE COOK OR JOHN DEMBOSKI. CLICK ON THEM FOR LARGER PICTURES. Tentative ID's by Federico G. Hoffmann. I'm open to suggestion if anybody can ID them any better.

The two above with shoulder marking are possibly Macrophyllum macrophyllum (juvenile)

This big guy above is possibly Chrotopterus auritus.

This above is likely Carollia perspicillata.

This guy above with the racing stripes may be Platyrrhinus dorsalis.
