A Bearded Tit (thanks to @susiemc) incredibly hard to capture, they blend into the brown of the reeds so well; you actually see the reeds moving in a way that is not down to the wind, zoom in and hope to catch them; I love the 'teardrops' around their eyes.
No worries Phil. I was just so impressed (and envious) because they're so incredibly difficult to see, let alone photograph. Reed warblers are ten a penny by comparison 😂.
