This morning brought the first Grey Squirrel to the so-called squirrel-proof feeder. It hung upside-down with its face in one of the ports before realising there was a load of seed in the tray. It seemed to eat a little before moving on - I guess their supplies in the woods are starting to run low. Pairs of Greenfinch and Goldfinch also visited the feeder, with a single Blue Tit first thing in the morning.
