This Bat was huge and flying around at 10:30AM this morning near coordinates: 37.0689958,-119.6528761
We do not think it is a Vesper. A local biologist thought hoary bat.
In an awkward location by a door on campus clinging to a trifoliate orange branch. Not sure how that happened. I moved it to a more sheltered location and within a minute or two, it spread its wings and flew off.
Seen on the Rich Mountain Loop Trail in Cades Cove
One photo seems to suggest it's a hoary bat.
One individual observed. It looked through my 100mm T5.6 lens that it was bigger than the other bats I've observed. It repeated what I imagine were it's feeding flights. It was using the airspace above a drainage area of the grassy/blue oak hillside slope. I was under eye level with it. It was 20-100 feet above my eye view. Nearby were the palisade rocky cliffs of Rockville Hills Park which look like they afford many cracks and crevices that would attract roosting and migrating bats. Also nearby were several shallow reservoirs. From the photo sequence it appears the bat flew near me and then flew to higher air and further away from where I stood.
Also included are tree photos show landscape below and to the side where the bat was seen flying.
