Bats

Bat
 

The bat species that have been documented in Yellowstone National Park are all insectivores (insect-eaters). A single little brown bat (Myotis lucifugus, the most common of the species) can consume 1,200 mosquito-sized insects in an hour, and can forage for 3–5 hours per night. The distribution of these species tends to be highly localized near sources of food, water, and roosting structures. They roost in natural habitats, including thermally heated caves, as well as in bridges, buildings, and other human structures, which can lead to conflicts with human use and historical preservation plans.
