A small, highly distinctive vanga. The body is slightly chunky, the bill and tail are relatively short, and, in keeping with its tree-climbing habits, the claw of the first toe is elongated (20 mm). The male has a narrow black band across the forecrown, lores, and chin. The rest of the plumage is almost entirely mid-blue . The bill is bright orange-red,. The female has a brownish green head, lacking the clear black eyestripe, but the forecrown is buffy forecrown. The rest of the upperparts are blue, but somewhat duller than the male, and the bill also is duller red than that of the male.
Nuthatch-Vanga is highly distinctive. Its small size, tree-climbing behavior, bright red bill, and blue upperparts all contribute to making this a bird that is all but unmistakable in the field.
Juvenile resembles adult female, but the underparts are tinged with blue-gray.

Rest of upperparts grayish blue-green, with ochraceous brown feather bases showing through on the rump and uppertail coverts.
