**Behavior and Ecology:**
– Big brown bats use echolocation for navigation.
– Modulate pulse intervals to overcome range ambiguity in cluttered surroundings.
– Males and females exhibit differences in habitat use.
– Roost selection based on diet and safety factors.
– Maternity colony bats display specific feeding behaviors.

**Health and Diseases:**
– Resistant to white-nose syndrome.
– Susceptible to rabies virus infections.
– Studies conducted on rabies prevalence in wild-caught bats.
– Research on regional blood distribution during torpor and arousal.
– Experimental infections with rabies virus in big brown bats.

**Conservation and Management:**
– Efforts include building bat houses for conservation.
