The genus Salpornis contains only one Indian and one African species, and differs in many remarkable respects from Certhia, although bearing a great general resemblance to it. It has an extremely long, pointed wing, with a minute first primary, and the second primary reaches to the tip of the wing. The foot is also differently shaped. But the most remarkable feature about Salpornis is that it builds a cup-shaped nest on a branch of a tree, thus deviating entirely from the habits of all other Creepers. The position of this bird requires further investigation.
Salpornis has a bill similar in shape to that of Certhia, but much longer. The tarsus is short, and the hind claw is much shorter than the hind toe. The tail is composed of twelve soft rounded feathers, and nearly square.
The sexes are alike, and the young are similar to the adult, and there is nothing to lead to the belief that there is any spring moult.
