Huber heading back to IH35 corridor

About 400k free-tailed bats left Huber Limestone Mine and headed back to Congress and McNeil on the first night after the SNOW!  Calm winds  – Temp 43F, Dew Point 36 F rising, but no precipitation.
We’re surprised to see them move on such a cold night.  They must know there will be little food in the Hill Country after that freeze and that their best shot at finding insects will be in the Blackland Prairie and IH35 corridor. Will they majority finally migrate now? Or will they try to overwinter? We’ll see!
