Rare passage migrant. Usually darker and slightly larger than the otherwise similar Lesser Whitethroat. An Asian specialty breeding in the mountains of Iran, rarely observed in the Western Palearctic.
Where in Kuwait
Found in similar habitat to the Lesser Whitethroat and the few records have generally come from the west at Al Abraq. It is distinguished from the Lesser Whitethroat by its slightly larger size (13–14 cm), slightly stouter bill, and the darker top of the head and darker grey-brown back, which gives it less contrast between its upper head to back region than in Lesser Whitethroat.
In the world
It has an extremely large range with a stable population and it inhabits upland regions from eastern Iran eastwards to the Tian Shan mountains of central Asia and the western ranges of the Himalaya. It migrates south to southern Pakistan and India in the winter, where it does overlap with wintering Lesser Whitethroats in some areas. Until recently, it was considered conspecific with the Lesser Whitethroat; today these are seen as members of a superspecies which also includes the Desert Whitethroat
