I started at Ferry Lane Rainham RSPB this morning to have a look what was on the river, but as soon as I did Paul phoned to say that Andy Tweed had found a Adult Sabine's Gull on the mud at Aveley Bay. Five minutes later lucky me was watching too. A great find! It stayed on the mud for quite a while so other birders got to see this rare Gull too. Also on the river was a good movement of Black Terns which was feeding mid river as were 3 Little Gull. Had Tree Pipit over and Wheatear and a couple of Yellow wagtail. I had a real good morning but I wasn't the only one, Paul had a cracking morning on his patch at Barking Bay! And last but not least, manged to see the Red necked Phalarope on KGV on Saturday too. Phew! Thanks goes to both finders, you made a lot of birders very happy this weekend.
