Pink-footed Geese
A quick walk before work to the overflow this morning produced little of note on the water, but a skein of around 100 Pinkfeet flew over (and I picked them out on call, which is unusual for me these days). My estimate at the time was around 70 birds, but counting from the photo it seems there are more like 104.
They flew North-west and then circled back west over Ealees valley before disappearing over the hill.
