Don't miss the dunnock!

Well done, sun -- good try!
You briefly drew a circle in the sky
But the clouds won.
Bad luck, sun!

On Day 6 of my consecutive bird shots, I give you a bluetit's head, a great tit's bottom, and don't miss the dunnock,  who's hoping for peanut crumbs to drop. He's so well camouflaged, he'd be easy to miss, which is why I've made him my thumbnail.)
