A large flock of Finches joining in the mobbing activity of a noisy Blackbird this morning. Mostly Green, but Chaffinch, Goldfinch and a couple of smart male Bullfinches too. I’m guessing Tawny Owl was the subject, but it remained unseen. A Little Egret on the scrape with about 30 Godwits which flew off as I arrived. Later on one of the female Marsh Harriers flew over the reserve and on over the reed-bed, suddenly swooping in but came up a minute or so later empty clawed!. A sweep over the remaining reed-bed showed the other female Marsh Harrier too.
