Along with at least one great white egret, were 3 or 4 marsh harriers regularly quartering the reserve, and a peregrine zooming around all the time that I was there (~2 hrs). One of the harriers had a green tag on its wing and apparently is a female from Suffolk.
In front the the hide a pair of stonechats came very close and gave us great views. (Click on the photos to enlarge and view as a slide show).
On the drive to the reserve through the narrow lanes bordered by rhynes, the damp fields were playing host to lots of winter thrushes and starlings.
I also managed to capture a quick snap of snipe overhead:
Although cool and blustery it was quite a good day, with other highlights including a chiff-chaff, big flocks of starlings, a kingfisher and a trip to Aldi for some stollen!
