Short stout bill Yet again, we have a rather plain brown warbler with a prominent supercilium. With little brown jobs like this, the first thing to rule out is Wren, which has a much shorter tail and has barring on the wing and flanks. The rich brown colours and clear supercilium steer you towards Cetti’s Warbler, or the rare Dusky and Radde’s Warblers. Cetti’s has more rufous plumage, with a grey breast and pale-tipped undertail coverts, and a much shorter supercilium. Radde’s and Dusky are very similar, but the former has wings brighter than the back (like here), warmer plumage, strikingly pale legs and a stubbier bill. It also has peachy ochre undertail coverts. All these features are shown in this bird, which is a Radde’s Warbler.
