Male mute swans (Cygnus olor) in spring love nothing more than picking on a particular Canada goose and chasing or flying after it until it is forced to step out of the water. Minutes later, the goose steps back in and the chase resumes. The chase starts with swimming, and the swan's powerful legs will usually allow it to corner the goose in a corner of the lake or pond. Occasionally, as a more extreme measure, the swan will take flight. Canon 7D MkII camera with Canon 70-300 mm zoom lens.
