An evening walk with Amy along the thames, from the O2 eastwards, with Juv YLGs on my mind and mudlarking on hers, was fruitful for both.
The right-hand bird is a brute, classic (probably male), it was joined by the nice contrasty bird on the left, which, although smaller, shares the features i look for and certainly looks good for a Yellow-Leg, although I didnt see the open wing or tail pattern. The tertials have a slight notching to them, which is acceptable and well within range for Michahellis and this patterning is limited to the tips.
Evening light looked great but ruined this photo in a way… Such a great tail pattern. I also noted a pair of Oystercatchers and a single common sandpiper along the water’s edge.
