Conservation Status: Threatened.
The Northern Long-Eared Bat, as the name implies, has long ears unlike other species in this genus, and is also more solitary in its roosting and hibernating habits. These bats are strongly associated with large blocks of older forests and they forage along wooded hillsides and ridgelines.
White-nose syndrome disease and human activities including forest habitat destruction and fragmentation, environmental pollution, mining, fracking, wind-energy projects, etc. have all caused the population of this species to plummet by nearly 99% compared to two decades ago (https://www.biologicaldiversity.org/species/mammals/northern_long-eared_bat/index.html). This flying mammal, once common in much of the northeastern half of United States and all Canadian provinces, has been listed under the ESA as a Threatened species since 2015 across its current range in 37 states (https://www.fws.gov/endangered/)
