Description

The smallest of the grey ''Melaniparus'' tits of Africa, the acacia tit has a glossy blue-black cap, nape, throat and breast contrasting with a large buffy white patch which extends from the bill to the sides of the neck. There is a broad black band which stretches from the breast to the vent. The upperparts are grey with white panels in the wings and there is a white spot on the nape. The underparts are greyish white, broken by the black band. Legs and bill are slate grey. The females tend to have a narrower band than males. Juveniles are similar to the adults but are duller.
