Does anyone know of any photos of the Dusky Warbler in Malta (6th record) on 1st Oct 2009, other than that published in the January Birdwatch? There’s a few things that don’t quite seem to add up.

Just to get a few caveats out of the way first – I’m not 100% sure it’s bill isn’t slightly open (often shown by birds in the hand), I can only find the one photo and I didn’t see or perhaps more importantly hear the bird in the field (or in the hand).

......but even with those caveats out of the way, I’m still asking if this is a Dusky Warbler due to (a) supercilium seems to flare more than it should (b) bill seems slightly thick (c) upperparts looks too olive (d) underparts lack the characteristic brown wash (e) primary projection looks too long (f) legs looks slightly thick (g) tail seems rather long.

So what is it? I’ve seen a pale Willow Warbler masquerade as a Dusky Warbler for several days before, and I’m not confident the same mistake hasn’t been made here.

Opinions please.

The only images of Dusky Warbler from Malta on Surfbirds are these.

The latter looks fine to me, despite the head pattern, check out the long length of p1 beyond the primary coverts.

Many thanks Brian.

I’m back-tracking now....looks like the clincher is the lengthy P1. Svensson states P1 of Dusky and Willow Wrb overlap slightly, but I can find no Willow Wrbs with a P1 as long as Malta bird.

Too much emphasis placed on bird’s colouration I think, shouldn't have waded in without considering everything.

Looks like a bang-on Dusky. The head pattern in the second pic seems normal to me - it also shows the slightly darker upper border to the super. Perhaps the Birdwatch pic isn't really representative Ross?

I would say this, but it felt less like a Dusky in the pic in Birdwatch...the bill looks thicker, the supercilium more flared and I thought it's feet and claws looked big. Importantly though, the tell-tale P1 is more than obvious in the pic in Birdwatch.
