1,600 bats fall to the ground during Houston's cold snap.

Some 1,600 bats found a temporary home this week in the attic of a Houston Humane Society director, but not because they've made it their roost.

It was a temporary recovery spot for the flying mammals after they lost their grip and fell onto the pavement after going into hypothermic shock during the city's recent cold snap.

On Wednesday, more than 1,500 will be released back to their habitats — two Houston-area bridges — after wildlife rescuers scooped them up and kept them warm by giving them fluids and keeping them warm in incubators.

Mary Warwick, director of wildlife at the Houston Humane Society, said she was holiday shopping when cold winds reminded her that she hadn't heard how bats were doing in the unusually cold temperatures for the region

So she went to the bridge where more than 100 bats lay dead on the ground.

But during his 40-minute drive home, Warwick said they began to come back to life, chirping and rolling around in a box where he collected them and placed them on his heated passenger seat for warmth.

She placed the bats in incubators and returned to the bridge twice a day to collect more.
