A very active small bird, with mottled brown plumage and white breast, they have stiff tails which they use in a similar way to woodpeckers, for support when climbing. They have large feet with sharp, arched claws and a long, slender curved beak to enable them to extract inserts and seeds from crevices.
There are several species worldwide, one UK resident and the rare, short-toed treecreeper from European which are very similar in appearance but can be distinguished by their different calls and songs.
They usually nest at the beginning of June, around the same time as tits, to take advantage of the same glut of caterpillars. They generally nest squeezed behind a piece of hanging bark, lining the cavity with a bed of tiny twigs, leaving two openings, one for an entrance and the other, an exit.
This wedge shaped nest box has been precision cut from European birch plywood and treated with a non-toxic animal safe preservative. Designed to encourage these fascinating little birds to nest in your garden, it has a small hole on either side of the box for the bird to enter and exit with a slot in the base for drainage, to keep it dry.
The roof is hinged, providing access for cleaning. Best mounted on the trunk of a tree, there are two fixing holes in the back panel. It is suggested that the box is placed near some natural cover, such as ivy.
