Tai Shan, "sub-adult" Giant Panda greeted his mom and dad at the "howdy" window this morning. He seemed to revert to a little cub, rolling in from of them to get their attention and seemed to want to play. I only captured Mei Xiang (mom) with Tai, but Tian Tian (dad) had been there watching Tai prior to Mei. Video captured via the National Zoo's panda cam.
