Visible flight at night. During the day there is vocalization and guano
on a business trip to San Antonio and Austin I had a free evening to visit the famous congress ave bridge
Mexican Free-tailed bats coming out from the congress ave bridge in Austin for their evening meal
The people guiding the boat tours were shining red lights on the bridge
Hanging out right above my doorway... and so close to Halloween! A gift and natural decoration.
I came across a small bat that seemed to be struggling and dying. Around 1500 Pacific Time Zone, the bat seemed to struggle to fully extend its wings and crawl/fly to safety. That bat then went to its back and seemed to cover its eyes from the sun. A bodily discharge can be seen in the photos (yellow in color, possibly urine). I moved the bad under a tree and out of the sun to minimize and further suffering and from drying out in the sun.
Orient Land Trust in Moffat, CO leads tours to the bat cave to watch a spectacular outflight of approximately a quarter million bats every summer evening.
Couldn't get any detailed images of individual bats, but the cloud was beautiful.
This was a special occurrence: We had recently completed the construction of the new photo blind at the Refuge HQ, and formed it to look like a "pseudo-cave" type structure. Here two *real* Mexican Free-tailed Bats found it to their liking for a roosting site. Notice the "free tail" on one of the bats.
