Bats from the local bat colony litter the walls of the America Tower after Waugh bridge gets flooded

The bat colony at Waugh bridge was among the hundreds of wildlife affected by the flooding caused by Tropical Storm Harvey in the Houston area.

On Sunday morning, hundreds of bats abandoned their home on the bridge to find refuge in surrounding buildings, primarily the America Tower off Allen Parkway and Waugh.

"Around 4 a.m. it looked like the movie 'The Birds' because there were about a thousand of them in the air," a maintenance man told Chron.com on Sunday. He didn't want to give his name, but he said that they regularly go to the tower to find refuge whenever the Buffalo Bayou waters get too high.

While there were several dozen hanging along the windows of the building, the building's personnel also said there were more in the garage of the tower. Maintenance people told Chron.com that they don't plan on doing anything with them because "what can you do."

Even if the bats wanted to flee their current hiding spots, the wind rushed too hard for them to fly against the force of nature, so many of them were stuck in the hiding places they found as of Sunday morning.

While visiting the bat bridge, a few chirps from the flying mammals could still be heard from under the overpass, even though the water was a mere six inches from engulfing the bottom of the street.
