Cistícola dorsigrís

Identificación

The grey-backed cisticola is a small, 13–14 cm long, vocal, dull-coloured bird with a dark rufous crown to its reddish head. It has a rufous panel in the folded wing. The grey bill is short and straight, and the feet and legs are pinkish-brown. The eye is light brown.<p>The southern form, "grey-backed cisticola" proper, found in southern Namibia and South Africa has a grey back heavily streaked with black. Its underparts are greyish white. Although cisticolas can be very similar in plumage, this greyish subspecies is quite distinctive. The northern subspecies has a brown back heavily streaked with black and cold buff underparts. It is very similar to the wailing cisticola, Cisticola lais, of eastern South Africa, but that species has warmer buff underparts and does not overlap in range.<p>The sexes are similar, but juvenile birds are duller with a yellow face.<p>The call of the grey-backed cisticola is a soft prrrrt followed by a sharp wheee phweee.
