DALLAS (AP) — Birds, bats and other wildlife appear to have taken a beating during the winter storm and deep freeze in the southern U.S. Scientists say it might take weeks or months to determine the extent of the harm. But dead robins and other songbirds are being found on yards and sidewalks. And rehabilitation specialists are nursing starving bats found on snow-covered grounds. Experts say migratory birds in the region don’t fatten up for winter because the South usually has mild weather and plentiful food. Naturalists also worry about habitat for monarch butterflies and other vulnerable species. Officials say there may be fish kills in some waters.
