What's that noise?

Today I was raking up cut grass from the meadow when, in the distance, I could hear the sound of geese then I had a real treat, a skein of around 40 flew directly overhead. It was like being in the tundra (I think?)

The sky has been quite a spectacle, there are still swallows around, plenty of crows, a buzzard being mobbed and then a red kite flew over to check for carrion.

Currently I feel stiff as a board, not sure if that's from raking for hours or craning my neck watching all the bird life??
