Uptick in free-tailed bat calls during the day and sure enough, 3 big flights from Congress Avenue Bridge in the evening!
First at 5:47 pm, next at 6:27 pm, and last one at 6:47 pm.
This is a good week earlier than normal for the Congress colony.
Recent studies have shown Tadarida have been migrating two weeks earlier than usual the last few years, but this ups the ante even more.
Zero government funding. 100% community-powered. Every dollar goes directly to bat care and education.
