I am sitting at my kitchen table enjoying my tea and toast and watching the best morning entertainment. Not on the telly, but outside the kitchen. The bird feeders are busy with chaffinches, blue tits, great tits, greenfinch, coal tit and siskens, while robins bob about on the ground underneath, chased by the greedy blackbird. As I watch there is a movement in the bushes behind the feeders and the birds take flight. But this is not an approaching predatory sparowhawk, but one of our regular visiting squirrels.
