Bat House Forum

Erik, Joe, Here in PA we are to contact the game commission when finding all downed bats. A ban has been placed on all bat rehab here in PA for the time being.

So far, my numbers of little browns are down slightly, but we have had many cool nights with few insects flying so I know that is a factor. WNS is about 200 miles away from me in central PA. I'm guessing by next year I may see a real decline in my numbers of little browns unless some kind of mircacle happens.....

Tuesday, June 9th I am going to Oil Creek State Park where there are about 1200 little browns. I will be able to tell more then by how much guano is under the bat houses there.

Checked these boxes last night and am guessing I've got 250 - 300 little browns using these 2 and 3 other boxes close by........This colony has grown each year.........I think eventually I could get 1,000 bats here. I hate to think of what's to come with wns........Somehow I think some bats will be resistant and we bat house enthusiasts can help populations recover...........

I wonder about that too. Around here (west of the Cascades in the PNW), some little browns stay in attics in the winter, and even wake up and feed if we get a warm spell. I would guess that attics may be less susceptible to WNS since they get warm now and then even in the winter? i.e. bats in attics may experience less mortality than bats in caves? But that is just a guess. I imagine we will find out eventually.

Dave, big brown bats do that same thing here in NWPA.........so hopefully there will be pockets of bats that survive.........and all that we have learned in the past few years will be of some use in helping populations recover......

Counted approx. 190 little browns emerge at this site tonight.........I have since replaced both boxes shown in the pictures with bigger ones.......Usually my numbers don't peak until May 15th, so this is a really good sign to have this many so early!

250 little browns at this site on 5/24/2011.....another 25 across the creek in 3 other boxes...........am thinking after pups are born there could be close to 400 bats at this site! I'll try to post some pictures of the new larger boxes here soon!

Great news Terry.
We had another wind storm last evening so the crazy weather streak is continuing. We lost pwer from about 6PM until 4AM. The bat houses all survived the wind although my wooden pole appears to be leaning from plumb today.
I have about 65 bats total now, down from almost 200 earlier.
I am going the wrong direction in numbers.
