The Squirrels must know that Luna can't get to them through the closed patio doors and seem to be teasing her.   This little one went on to dig in the border trying to find one of his buried walnuts.
The extra is of a Buzzard that landed in the paddock across the river.    Not a very clear shot as I took the photo through glass.   I didn't want him to fly off if I'd tried to go out into the garden.
