I took this picture while walking to work when we still had snow on the ground, at around the end of March. I had been walking past this spot every morning and the place was swarming of swans every time I passed. I had just gotten my 2x extender so I figured I'd test it out with my 70-200mm lens. I had this idea of getting a shot of these swans landing on to the water, but instead I caught up these two lovers mating (I guess; I have another picture of the other swan jumping on and humping the others back). This picture was taken AFTER the act. ;)

Taken with 6D MkII, Canon 70-200mm f2.8L MkII & Canon x2 Extender. I'll put up the exact details of the shot once I get home and check them out.
