I was on duty Sunday and here are some sightings I had around the reserves. 

A great selection of wildfowl and waders were gathering at high tide in the afternoon at Cliffe Pools.  At least 1,500 Dunlin were observed streaming onto the beach at Flamingo to roost (see photos attached).  14 Goldeneye were present on Flamingo, with 5 males displaying to 6 females, and birds of prey noted were Merlin, Marsh Harrier, and fantastic views of a hunting Short-eared Owl by the Thames Viewpoint (see attached photos). 

At Northward Hill the Rough-legged Buzzard was showing really well from the Marshland Viewpoint.
