Our first night we were delighted by the emergence of the more than one million Mexican free-tailed bats that live under the Congress Avenue bridge in Austin. We had a perfect view of the bridge and the river from our nice rooms at the Hyatt Regency Austin and had front row seats for the bat emergence aboard Capital Cruises double decker paddle wheel river boat.
It's remarkable that these creatures decided an urban bridge was the perfect place to call home. Friend and bat expert, Sara Weaver enlightened us about bat behavior and habits. We learned for instance, that much of the Austin bat population recently tends to over-winter rather than migrate because the insects that they eat (by the ton) are not migrating as much either. This is thought to be due in part to warmer winter temperatures. Maybe they just love it here in Texas as much as we do.
