Hi Bruce,
Regrettably, I don't think that a firm identification to form is possible here, at least not from the sole image, but, while I share Ken's opinion that this bird doesn't look right for a halimodendri candidate, it may well be worthy of consideration as a possible blythi. However, without a DNA sample, or at least recordings of calls, I don't think that the identification as such would be safe, and perhaps it's just a late browner than usual nominate, even if I suspect that most of the birds this late are likely to be blythi (this is just a theory, mere supposition, and I'd not read too much into my ramblings on this matter!).
Regards,
Harry
