Northern Long-Eared Myotis

Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. Northern long-eared myotis (Myotis septentrionalis) are small bats, typically 5-10 g and 84 mm in total length . The fur is dull brown on the dorsum and yellowish on the venter. Compared to other Myotis species, these bats have long ears with a relatively long tragus in each ear.Females give birth to 1 pup each summer and often form large maternity colonies (30-60 individuals) consisting mainly of females and their young. In the fall, northern long-eared bats migrate to caves to hibernate. Migration distances are not known for this species. Northerns are often found roosting singly in caves, rather than in the large clusters typical of other Myotis species, like Myotis sodalis.
