FOREARM
Measure!!
For the love of all

the forearm!!!
Over 40mm and
brown =
big brown bat
FOOT
If forearm is less
than 40mm, might
need to measure foot
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
