absent swans

there was some lovely light this evening so I walked down to the river hoping to capture the  swans that are almost always in the area.  I've been photographing the same pair and their cygnets for at least six years now and have blipped them on numerous occasions. Sadly I was told the male was swimming around in circles and thought to have had a stroke. He was taken to a swan sanctuary and they came back yesterday to take the female to join him. If anyone knows of any swans needing a nest, good condition,   ideal first home, theres one going free here.
