Did a couple of hours at Farmoor Reservoir today with Jacob. Ebird list HERE. Highlights included the 3 Black Terns that have been around a few days, 8 Common Sandpiper, 4 Ringed Plover , 1 Oystercatcher and the usual Yellow-legged Gulls.
Black Terns (above and below)
Common Sandpipers- I counted 8 but another birder had 9. There were 3 Sanderling here yesterday, and a couple also at nearby Grimsbury Res in last couple of days. At Beddington in the week there was Turnstone, Whimbrel and a few Greenshanks so waders have obviously been on the move in the last week in the easterly airflow.
First-summer Yellow-legged Gulls (above and below). The top bird has dropped three primaries and the bottom bird six, with the covert moult also more extensive in the bottom bird.
