Black Swan

Very unusual to see a black swan on the river here at Northam, its usually the only habitat where we see the white swan, they had a breeding programme  for the white swans at Northam, this is first time the river was void of all white swans? very strange, we shall have to find out what has happened to them, maybe they have shifted location? 
We had a lovely day travelling through Mundaring, York then onto Northam, it was very warm today 23c but its to be short lived as another cold front is moving in, its officially noted that its been the coldest September in 6 years...
