Bats, birds among wildlife that was pummeled during freeze
DALLAS >> As many people in the southern U.S. hosted neighbors who had no heat or water during the vicious February storm and deep freeze, Kate Rugroden provided a refuge for shellshocked bats.
Starving and disoriented, the winged mammals tumbled to the snow-coated ground as temperatures plunged to levels rarely seen in the region.
“They burned through their energy reserves as they tried to wake up and get away from the cold and ice,” said Rugroden, of Arlington, Texas, one of numerous rehabilitation specialists nursing stranded bats plucked up by sympathetic people. “And there aren’t any insects out there for them to eat yet.”
Bats are among numerous wildlife believed to have taken a beating in the South, a region unaccustomed to such a severe and prolonged cold snap. Many species migrate there for winter precisely because of its normally mild weather.
It might take weeks or months to determine the extent of the harm, but anecdotal evidence is already turning up, including dead robins on yards and sidewalks.
Alligators in Oklahoma’s Red Slough Wildlife Management Area were photographed with snouts protruding from frozen waterways, which is a survival maneuver enabling them to breathe while their bodies go dormant to conserve energy.
Fish kills were feared in Arkansas and Louisiana. The Texas Parks and Wildlife Department said it expected casualties among exotic deer and antelope. Across the Gulf of Mexico coast as far east as Florida, naturalists worried about monarch butterflies and the milkweed plants essential to their survival as they prepare to migrate northward.
“Animals can respond to events like this by moving elsewhere, but if it’s beyond your flight range or your walking range you have to hunker down,” said Perry Barboza, a wildlife biologist at Texas A&M University. “Some animals like small birds can do it just a night or two. The duration becomes the killer.”
Sea turtles stunned by frigid Gulf coastal waters were still being cared for at facilities this week. More than 10,600 had been found and officials were tabulating how many died, said Donna Shaver, Texas coordinator for the Sea Turtle Stranding and Salvage Network.
Fish kills along the Texas coast were expected for recreational favorites such as spotted sea trout and red drum. In Louisiana, officials said it could take a week for dead fish to wash ashore. The Arkansas Game and Fish Commission warned anglers to expect die-offs of threadfin shad, a primary food source for lake species such as bass, walleye and crappie.
While extreme weather is particularly dangerous for imperiled species, the whooping crane — listed by the federal government as endangered — appears to have weathered the storm.
