Had a quick look at Farmoor this morning with Jacob. The wind and rain was a bit much for him so we only lasted an hour before he started grizzling. Managed to see one of the 4 Shags that were around (a group of 11 arrived in late August and these are remnants of that group), two juvenile Knot were on the causeway, had 2 Black Tern flying around (17 were reported moving through today) and there were at least 1000 hirundines- a lot of them House Martins and also a few Swifts.
Juvenile Shag
Juvenile Knots
Bird 1: A darker individual overall and with heavier markings on the underparts and a stronger face pattern. Longer billed too.
Bird 2: An overall paler bird, with fine streaking, shorter bill and weaker face pattern. A good example of intraspecific variation. Presumably these bird are siblings.
Black Tern- looks like a visible moult limit in the primaries indicating an adult bird
