This camera shy pink-backed pelican from the Twycross Zoo in England shows visitors and the camera that he doesn't like it when anybody or anything is getting too close to its fence. <br /><br />The video, captured on October 25, sows the bird biting the fence of its enclosure as it tries to push the camera away.<br /><br />"The water bird goes into attack mode and after he had several goes at the fence, he moves away from it and has a go at his mate" the filmer wrote. <br /><br />"The mate seems to know better and won't argue with him and just moves further along the tree trunk."
