Curruca nana
The Asian Desert Warbler is a rare and occasional visitor to Britain, typically seen during the autumn and winter months, often in coastal areas with scrubby vegetation. It is most likely to be spotted in the southern and eastern parts of the country, particularly during periods of easterly winds.
Use these features to identify Asian Desert Warbler in the field.
The Asian Desert Warbler can be identified by its pale yellow-brown upperparts, white underside, and distinctive white eye-ring, as well as its long, graduated tail and short, pointed bill. Its greyish-brown wings and tail also have a distinctive pattern of darker brown edges.
The Asian Desert Warbler is slightly smaller than a House Sparrow, measuring around 9-10 cm in length.
The male Asian Desert Warbler has a pale yellow-brown back and wings, with a white belly and pale yellow throat patch, and its plumage remains relatively consistent throughout the year.
The female Asian Desert Warbler is similar to the male, with a slightly duller and more subdued colouration, but overall the sexes are alike.
The Asian Desert Warbler's call is a sharp, high-pitched "tak" or "tek" sound, often repeated in a series, while its song is a melodic and repetitive phrase, typically consisting of a series of whistled notes.
The Asian Desert Warbler is an active and skulking bird, often feeding on the ground or in low vegetation, and it has a distinctive habit of flicking its tail upwards when alarmed or excited.
The Asian Desert Warbler can be confused with other warbler species, such as the Lesser Whitethroat, but it can be distinguished by its pale yellow-brown upperparts, white eye-ring, and longer, more graduated tail.
