Is this bird the rarity I think it is?

Having read Dominic Couzens’ piece on Cetti’s Warblers and how rarely they are seen, I saw this. Could this possibly be a Cetti’s Warbler? Robin Sumsion

QAs Dominic said, the Cetti’s Warbler is very rarely seen, despite becoming a more and more widespread and numerous species. It’s brown, fairly nondescript, and perfectly adapted to blend in with its preferred habitat, in which it tends to skulk and hide.

AEven when they are heard, they are incredibly difficult to actually spot. That being said, some of us are either better observers or luckier than others. This bird is definitely looking good for a Cetti’s to us, from that supercilium (‘eyebrow’) and eye-stripe to the colouring and spotted undertail coverts. We can’t quite count the tail feathers, which is a pity, as Cetti’s Warbler is unusual among passerine birds in having only 10 tail feathers, rather than the more usual 12. Well spotted!
