Yesterday, on arriving back home after an exhausting hour discussing polyfilla and sawdust (don't ask), I looked out of the back window and there was a Waxwing in the guelder rose bush. It immediately flew off. I then went into the sitting room and, on drawing back the curtains, again saw a Waxwing (the same one?) in the bush. It flew off after three seconds. The photo above is not mine, there was no time for that sort of flimflammery.
Today, after nailbiting hours of covert ops, I can now report that my guelder rose is at no risk whatsoever from attack by Waxwings. So, you Starlings and thrushes, help yourselves - no hurry, because no competition - the Bohemians have buggered off back to Waxwingland.
