I learned that pallid bats wings' beat 10 beats per second, pallid bats also roost in colonies of less than twenty bats and Rafinesque's big-eared bats will roost in man-made towers.
There are six main viewing spots in Texas for Mexican Free-tailed Bats. They are: Bracken Cave, Stuart Bat Cave, Devils Sinkhole SNA, Eckert James River Bat Cave Preserve, Old Tunnel WMA and Congress Avenue Bridge.
There are around ten million to fifteen million Mexican free-tailed bats living under Congress Avenue Bridge. Mexican free-tailed bats save farmers millions of dollars by eating insects. Mexican free-tailed bats consume the worst pests of several crops including cotton and pecans.
I have been to the Congress Avenue Bridge to see the bats. I liked going there. I have always liked bats and wanted to see them up close. When I went to Congress Avenue Bridge mostly I sat on the grass and watched but I did go up on to the bridge. There was a good view from the ground and the bridge.
