The genus Anorthura contains two Indian birds which may be considered as permanent races of the Common English Wren. They inhabit the Himalayas, and are constant residents there.
In Anorthura the sexes are alike, and the young bird is quite like the adult. The bill is very slender and feeble, and about half the Length of the head ; the wing is extremely short and rounded, the first primary being about two thirds the Length of the second ; the tail, of twelve feathers, is shorter than the wing and not very much graduated, the outer feather being about three quarters the Length of the tail; the tarsus and the claws are long and slender; and the plumage is barred in both species.
The Wrens frequent underwood, creeping about, as a rule, and flying but little. They build massive nests and lay numerous eggs, which are usually spotted but occasionally white.
