This cave in Cuba had a huge number of bats, mostly in one room. These are, for the most part, Natalus lepidus (Gervais's funnel-eared bats). But the latin names have changes a bit recently, and I am not sure what exactly their name is right now.

This photo was taken with a 3Mp Nikon 990 over ten years ago. A similar digital photo from a modern camera would improve things, but I thought a nice photo from an earlier digital age would be worth having a look at.
