Weigh!
Measure nose to tail
Coat
Color
Some have banded fur
Color varies with age and
among individuals
Length
Furred tail membrane?
Furred wrists?
11. ToeHairs
For brown bats with
forearms under
40mm, might need
to examine toe hairs
Copious?
Long?
Usually need
magnification and
very good light to see
12. Keel
For brown bats with
forearms under
40mm, might need
to look at calcar
Yes!!
No!!

appearance to Little Brown Bats
May roost with other myotis
species or in small colonies of
conspecifics.
Found in deck umbrellas, tree hollows,
loose siding
Thought to migrate to caves for winter
BUT new information suggests this
may not be true
