In today’s Bat Week post, we’re checking out the adorable “California Leaf-Nosed Bat.” The California leaf-nosed bat (Macrotus californicus) is a gray-furred, medium-sized bat, which has a leaf-shaped structure on its nose. 

The ears are large (1.1-1.5 inches, 29-38 mm) and are joined near their base. Roosting leaf-nosed bats do not cluster in tight packs, as most other bat species. Total lifespan of California leaf-nosed bats is not known; however, one was recaptured after 15 years. California leaf-nosed bats do not migrate long distances nor do they hibernate. 

Instead they maintain a year-round presence by roosting in a cave or mine that maintains a high temperature (greater than 82ºF or 28ºC); many of these caves are geothermally heated.
