The Tree-Creeper is a common species, but from its quiet ways and dull colour seldom noticed. It is with us the whole year, spending its time in an unceasing search for small insects on the bark of trees. In its habits and food it is not unlike the Woodpeckers, climbing up with a series of jerks, and, when observed, shifting at once to the far side of the tree.

It has a short but pleasing little song, which is not often heard, and the call-note is a low and plaintive “cheep.” It is solitary in habits, and more than one are seldom seen together, except in the breeding season. The nest is placed behind a piece of loose bark and is merely an accumulation of roots, grass, and moss, with a lining of wool and feathers. The eggs are white, minutely spotted with reddish.

The sexes are alike and have the feathers of the upper parts dark brown with pale centres, becoming lighter on the rump; under parts, silvery white. Flight feathers dark brown, barred with buffish white. Tail feathers stiff and pointed and dull reddish brown in colour. Length 4·75 in.; wing 2·5 in.

It is common and abundant throughout our islands.
