Serotine

The serotine is a considerably large Eurasian bat with large ears. The long fur is smoky brown on the back and paler yellowish brown below, the nose and triangular ears are black, and the wing membranes are dark black or brown. It sometimes roosts in buildings, hanging upside down, alone or in small groups (Wikipedia, general species account).

It often hunts in woodland, usually low, 0 to 5m above the ground, and commutes an average of 6.5km to and from feeding areas each night. Females usually give birth to a single pup in early July, young make first flights at about three weeks, and at six weeks they forage alone. The account opened describes a Eurasian species, so its Nepal status is flagged. Nepal's 2011 list has no matching entry.
