This bat somehow got inside our cottage. I think it was inside for a few days because I noticed the hanging door curtains were moved each day, even though I was sure I had straightened them each day (they weren't moved today - I removed the bat from the cottage yesterday). I was drinking my tea when I noticed the bat on the floor in the doorway. I used a stick to flick the bat outside where it very slowly (5 seconds) opened its wings and hissed at me (first photo). Eventually it crawled away. Notice the curtain cotton around it's wings and feet. The deck boards are 6 inches wide for scale. I'll leave it for someone else to identify the species.

That looks like a Little Brown Bat to me. They are completely harmless and are actually good to have around to keep the bugs down.

Thanks. I know they are around because I often see them in the twilight doing their bat flight against the sky. A neighbour once had more than 30 in his attic - he watched them all fly out one evening and then he sealed their entrance opening. I never hunt - when I was in junior and high schools most guys hunted, and they all told me they took extra (poached). "I was allowed 24 trout, but I took 50." That left an indelible impression on me. Somebody had to conserve.

There is a chance that this may be a Northern Long-eared Bat, which occurs in western and SW NF. The photo bat4.jpg shows what look to be longer ears than those of a Little Brown Bat. The general rule is that if the ear is folded flat forward and extends beyong the tip of the nose, it is a Long-eared. The ear does not extend beyond the nose tip with the similar sized, similar-looking Little Brown Bat.

Thanks for sharing that diagnostic for distinguishing LBB from NLEB, Mac. It's hard to tell from the photos, in photo 2 the ears don't look quite as long. But it could be either species.

If anyone is interested in bats and wants to encourage them to hang around (but not in your cabin); it is very easy to build a bat box that may attract them. See for an easy building plan.

I think this is a Northern Long-eared bat as well; judging by the size of the deck boards it's larger than the Little Brown Bats. We've had bats in and around our cabin (Brigus Junction) for two years. I've built a bat house, but they still look for any opportunity to get in the cabin.
