Experts explain lake bird deaths, KLTV, January 6, 2011:
First, it was Arkansas, then Louisiana, now hundreds of dead birds were spotted on an east Texas highway. The birds were found this morning on the highway 155 bridge at Lake O' the Pines. It was an unsettling sight for several morning drivers along the 155 bridge, over a hundred clumps of gray feathers lining the roadway. Dead coots.
But why did they all die seemingly at once? Its a strange, but explainable occurrence. Game wardens say the coots stay together in large numbers and they were seen by the hundreds on the 155 bridge just a few days ago, the easy answer by the game wardens office, they were run over. The birds are easily startled, and fly low, over the bridge.
