File – In this Jan 18, 2012 file photo, a donkey used by protestors to deliver a petition with 100,000 signatures asking Gov. Rick Perry to stop Texas Parks and Wildlife from hunting wild burros in Big Bend Ranch State Park is seen at the capitol, in Austin, Texas. Texas wildlife officials said Tuesday, March 20, 2012 that the agency is suspending its policy of the killing burros after the Humane Society of the United States offered to try to devise a nonlethal plan to remove the animals.
