Bats at Foster Road

All free-tail roosts are not in caves. At the Foster Road overpass at Loop 306 in San Angelo, free-tails occupy narrow crevices on the underside of the bridge. They first arrive at Foster Road in late March and are wholly absent by the end of November. In the last decade, spring and early summer population has fluctuated between a few thousand and 150,000 bats. But from late summer through October, when maternity colonies have largely dispersed, up to 184,000 have been recorded. I would not be surprised to find over a quarter of a million of them here in October, (Terry Maxwell). Best time for viewing is at sunset. Bats
