The genus Certhia contains four Indian species which are, however, divisible into many geographical races. They are resident in the Himalayas and higher hills of Burma, moving vertically to some extent under varying conditions of temperature.
Certhia has only a single moult, in the autumn, Biddulph's opinion that ft himalayana. had both a spring and autumn moult being undoubtedly incorrect.
The young are coloured like the adult but have signs of crossbars on the lower plumage, especially on the sides of the breast and flanks, and are somewhat paler and duller.
In Certhia the bill is as long, or nearly as long, as the head, slender and curved downwards. The nostrils are long, narrow slits. The tarsus is scutellated and the toes and claws are extremely long.
The wing is rounded, the first primary being about half the length of the second, and the third a little shorter than the second. The tail and wing about equal in length and the former is composed of twelve very stiff pointed feathers and greatly graduated.
