very poor shot of the male Black Redstart at Walthamstow Marshes
There were at least eight male Blackcap singing along the path up to the Cornmill Car park, and a Sand Martin was seen flying over the river Lea near the footbridge next to Leyton Marsh.
At Waterworks NR, the Cetti's Warbler continued to sing, my first Swallow of the summer flew through followed by two (singles) Sand Martin, a Rook (another patch first!), flew lazily north, and there were counts of eight Common Pochard (seven drakes), two Tufted Duck, 11 Teal, and two Little Grebe.
Later over the Lea Bridge Road, a Red Kite soared high over.
