It's a Great White Egret (Ardea alba) Steve. Blooming enormous. Very long, elegant white neck,stands upright a bit like a stork.
Since I've been feeding the birds in our back garden, the inevitable seagulls have been descending to grab bits of bread which they try to swallow whole. But yesterday there was one among them which really stood out - a great black-backed gull (Larus marinus). He was the only one of his kind among the other common ones. We aren't all that near to the coast, but the gulls come inland to try and find food in the fields (worms etc)
The large crows still call out what sounds like "FOOD!!FOOD!" when I appear in the garden. Always makes me smile.
