Thanks Mike, With White Nose Syndrome wiping out some bat species and other stresses on them my work in the US has been pretty important. My tropical work also helps to conserve them in other places. They really are throwbacks, mostly unchanged for 50 million years, and have been a part of the landscape for a very, very long time. Our loss of them now is not without environmental consequences, and working to figure out where the remaining populations are is fairly important.
It's what I do in the summer, mostly, with error and variety coins in the winter while the bats are asleep.
