SWAN BOLERO

I was going past the canal today . The swans started doing synchronized swimmingon the surface of the canal. I got a good number of pictures of them. There necks swelled up .The male got on top, the female is about to drown, when her head came through the water .A few seconds later they were apart,then they started cleaning them selfs for a long time. One laying there neck right along it's body.
