Anyone care to confirm the ID of this bird before I put it in the gallery, its 1 of several that require a thumbs up. It was taken in the desert near Qatbit, Oman; no voice it was 44deg in the shade and it took everything to breath, I believe it to be Upcher's Warbler (Hippolais Languida) but Olivaceous (Hippolais Pallidais) is also a distinct possibility as they are both about at the time of year - mid april.
