Appearance
It is a small bird, 11.5–12.5 cm long. The sexes are almost identical in colour, pale grey-brown above with browner wings and tail, and whitish below; the bill and legs are yellowish, and the eye has a yellow iris. The song is a distinctive jingle often given in an advertisement flight, with a mix of clear and harsher notes.It has occurred as a rare vagrant as far west as Great Britain.
Naming
Until recently it was considered conspecific with the African desert warbler, but is now given specific status. The two are still each other's closest living relatives, and their relationships to other typical warblers are not clear. They may be fairly close to the common whitethroat; particularly, female whitethroats look much like a richly coloured Asian desert warbler. But it seems that all these three taxa are fairly basal members of the genus.The specific "nana" is Latin for "dwarf", from earlier Ancient Greek "nanos".
Habitat
It breeds in semi-desert and dry steppe environments, as long as some bushes for nesting occur. The nest is built in low shrub, and 4–6 eggs are laid.Food
Like its relatives, it is insectivorous, but will also take small berries; unlike most warblers, it commonly feeds on the ground.References:
