This bird appearing more like what I'd expect for a regular Wintering Chiffchaff, note the cheeks are quite dark & close in shade & hue to the crown, & if you squint or look from further back the bird appears to have a dark head. The breast, flanks & belly are closer in shade to the nape & mantle giving the bird a pretty uniform overall appearance. The eye ring is very obvious against the darker face, the legs brownish-black, & the supercillium (eye-stripe) narrow & clearly green-yellow even in dull, grey light conditions. Even the green-yellow streaking in the breast & flanks is obvious in the dull conditions. Compare these features to the birds photographed yesterday & the differences become more apparent, though there is a variation in individual collybitas.
