wow thanks for the great answers... I appreciate it! It didnt like dive bomb Diggy or anything but was swooping at him and Id say got as close as 3-4 feet from him I freaked, ran and grabbed Diggy and it continued swooping at me as well. It only got as close as about 5 feet from my head. I guess I will call DNR Monday as see what they think. If they usually are not aggressive, and scare easily it makes me even a little more weary as this bat was not scared at all

I knew we had them and see them lots but never get close at all they sit in my big tree and click like crazy at night.
