Silvery birds..

I saw these birds flying together backwards, up, around - staying together and showing up white/silver against the trees and dark clouds. I though seagulls but I've never seen them act like that. Maybe doves? They were quite fascinating to watch - I should have filmed them.
I got up quite early to clear up after last night. It didn't take too long to rinse bottles and plastic glasses for recycling. My son says he'll wash the floor as he surfaced when I'd all but done (standard!).
We have enough hog roast to last until Christmas..
Pork recipes welcomed!! :-)
