I've not found any info for our NW region on this being an issue, but we certainly do have lots of bat populations in the Columbia Basin and many new wind turbines in the area. That they only travel relatively short distances from roosts to hunt is probably a good thing in that any colonies affected would likely be limited to those living within a 5 mile range. http://www.latimes.com/science/scie...31108,0,1587861.story?track=rss#axzz2kC03oupr A bat can consume 2000-6000 bugs every day. With colonies ranging from 300-1000+ that's a lot of bugs. We watch them around our house during summer nights and they, much like swallows are like watching a Ferrari on a slalom course -- all work. If we find ourselves doing a little more swatting, scratching and DEET application next spring/summer, it could be because bat populations are being affected. Of course, that may make for some insane chronomid hatches...it's only November and I'm already thinking about the 2014 lake openers...it's been a slow fall season for me.
