Another view of two Sichuan Takins shoving each other around their enclosure on a rare warm sunny January morning at the St Louis Zoo. This went on for at least 10 minutes or more...with occasional breaks and some cheek-to-cheek time. A youngster was nearby watching and moving occasionally to stay out of there way!
