Hide and seek!

This week I have had the pleasure of my own ongoing wildlife comedy show right outside the kitchen window. The super stars are Squidge and Squish the squirrels and the tiny woodmouse, I've called him Willie, but they never appear together.
It all started when I refilled the squirrel's nut box earlier this week. Now when I do this and Squidge comes down, he thinks there's going to be a shortage any time soon so he eats two and buries one. This goes on for a considerable time while Squish sits on the fence and watches him.
Once squidge has finished and left the premises, Squish comes down and eats a few nuts from the box and digs up some of the ones that Squidge has buried.
Later in the morning when the squirrels have gone home, Willie comes along and he too digs up one or two nuts, he must smell where they are. These are almost as big as him, then dashes off with them and disappears under the edge of the fence where I think he has a little hole down into his burrow.
The next day when Squidge comes into the garden, he has a few nuts from the box then goes to dig up some of the ones he buried the day before. It's quite amusing to see him dig where he thinks he left one, but can't find it. Eventually, he'll dig up a few if he can find them and eat them.
I sometimes wonder whether the squirrels realise that the nut box never gets empty. Perhaps if they did, they wouldn't bother to bury any for another day and besides, I've never understood why they dig them up the day after they have buried them anyway.
