You Must Eat Your Greens!

We kept the Birthday celebrations going today which was lovely but after I dropped Julian home I needed a good lay down to get over it all!! : )
Took a long walk late this afternoon at Hyde Park and spotted this Black Swan family who were gorging on some sort of green algae (perhaps) covering one of the lakes. 
Such beautiful big birds and the father bird was hissing at all of us who were gawking at them, I imagine he was saying step back you fools!! : )
Thanks everyone for all the birthday wishes xxxxx
