There are no current endangered bat species, but bats do face threats fueled by climate change and White Nose Syndrome (just to start). WNS has killed roughly 6 million bats to date.
Bats on the sensitivity/threatened (likely to soon become endangered) list:
Spotted bats (Colorado's rarest bat)- there were two observations recently! One was around Montrose and another was near Hotchkiss. Latta noted this was an exciting sighting for BLM workers.
