Mexican Free-tailed Bats
Mexican Free-tailed Bat also known as the Brazilian Free-tailed Bat (Tadarida brasiliensis mexicana: Molossidae) It is the official state bat of Texas and Oklahoma and happens to be the icon for Bacardi rum. These colonial nesting bats are 8.9-10.2 cm (3.5-4.0 in) in length with a wingspan of 28.0- 35.6 cm (11-14 in). Nine subspecies are recognized with two being in Texas. Subspecies mexicana is the most abundant and is migratory while subspecies cynocephala in a non migratory subspecies. Photographed at the US 77 crossing of Oso Creek, just south of Riviera, Nueces County, Texas, USA. Creekside at ca. 2 m (6.6 ft) elevation. They roost in the day time in the bridge expansion joints. These photographed bats are in the expansion joints, I was below the bridge looking up shining a flash light in the joints. On two occasions at dusk when the bats fly out, I witnessed Harriss Hawks gather near by and get in the middle of the fly out and snag bats out of the air.

This is so, so cool! A terrific closeup of these critters Stanley.

Gotta set me up a bat box.
Superb close-up and excellent detail. They probably should contact Bacardi for a more spacious home (trademark infringement, LOL).
Well....that clears up the Bacardi Mystery for me. Nice scouting and shooting Stanley. Terrific job here. Excellent description too.
