Seed Head

I took a walk at Needham Lake this afternoon, there were a few butterflies and damselflies but they didn't stay still long enough to photograph. I noticed this seed head, the stalk was far too long and hard to be a dandelion, but must be from the same family I would expect. The sun was bright and it looked a bit washed out so I've converted it to black and white and like how some of the seed head look like spiders webs.
I also noticed that the Swan family now has only five cygnets, so they have lost three now. I wonder what is taking them as they are growing quite big, it's so sad seeing the numbers decrease like that.
