bat rescue

We rescued five bats from our woodstove and its chimney tonight. Two we brought out by hand (in gloves, of course), and three by opening doors and shooing them. I think they were Little Brown Bats (Myotis lucifugus)—using Stokes Beginner's Guide to Bats for identification after the fact. Even after all that time in Carlsbad and with DR in Montana, I'd forgotten what to look for.

Big Brown Bat
Eptesicus fuscus
Length: 3.4 -5.4"
Wingspan: 13-16"
Weight: 0.4 - 0.8 oz
No fur on wings, tail, ears, nose, which are dark brown/black
Little Brown Bat
Myotis lucifugus
Length: 2.4 - 4.0"
Wingspan: 9-11""
Weight: 0.2 - 0.3 oz
Long hair on toes, small black ears

What we saw: medium brown fur, slightly ashy. Slighter darker ears, wings. Didn't look closely at their feet. Hairless wing membranes, naturally. They looked more like the little brown bat pictures, what with the proportion of eye size to head, nose not noticeably black.

We took some photos, but they were hopelessly inadequate. Oh well. Luckily, there's google.

Turns out the Montshire Museum did a week of "Montshire Minutes" on bats. And here's s brief natural history summary from Mass Audubon as well.
