Description

The southern white-crowned shrike grows to a length of about 24 cm (9 in). The sexes are alike; in the adult bird the crown and forehead are white, and the mask is black and extends above and below the eye to the side of the neck. The nape and upper parts are ashy-brown and the wings and tail are dark brown. The underparts are off-white, the upper breast being tinged with buff. The lower belly and vent areas are ashy-brown. The beak is black, the eyes brown and the legs dark brown. Juveniles are similar to adult birds but the crown is slightly mottled and barred and grey rather than white. The chin and throat are white but the remaining parts of the underparts are tinged with ashy brown. [2]

Ecology

Like the closely related northern white-crowned shrike, this species is highly sociable and will form small, tightly-knit groups of usually three to six individuals, but occasionally up to twenty outside the breeding season. They are not in general aggressive birds but will attack predators such as birds of prey. When foraging, they sometimes associate with Tockus hornbills, feeding on the insects they disturb as they walk around. Members of the group engage in cooperative breeding, join together in building a brooding nest, take turns in sitting on the eggs, and assist in the feeding of nestlings. [2]

Status

The southern white-crowned shrike has a very wide range and is described as being very common in places, though rare in others. No particular threats have been recognised and the population seems stable. The International Union for Conservation of Nature has assessed its conservation status as being of "least concern". [1]

The throat, neck sides and underparts are white, with orange flanks and breast. The female is a duller version of the male, with brownish black upperparts and a grey or buff tone to the shoulders and underparts. The juvenile has grey-brown upperparts with a paler forehead and barring from the head to rump, barred off-white underparts and brown wings аpart from the white primary patches. The species' calls are short and grating, but the song has melodic warbler-like components.
