NUTHATCH

The 'nuthatches' are a family, 'Sittidae', of generally very similar small passerine birds found throughout the Northern hemisphere.
The nuthatch family, Sittidae, traditionally contained 23 species. The subfamily Sittinae held the 22 species of “true” nuthatches, and the subfamily Tichodromadinae held a single species, the unique Wallcreeper, ''Tichodroma muraria'', which is now separated in its own family, Tichodromadidae.
Most nuthatches are woodland birds, although a few species have adapted to rocky habitats. They have the unusual ability to climb down trees head first, unlike species such as woodpeckers which can only go upwards.
Nuthatches have big heads, short tails and powerful bills and feet. Their shape is distinctive, and all species are recognizable as nuthatches if one has been seen.
They are generally omnivorous, eating mostly insects, nuts and seeds. Most are resident, but the Red-breasted Nuthatch migrates from the north of its range.
Nests are in holes or crevices. In some species the size of the hole is reduced by the building of a mud wall.
The Eurasian Nuthatch includes in its song repertoire a single high pitched note that it repeats often from a high vantage point.
This group gets its name from the habit of the Eurasian Nuthatch of wedging a nut in a crevice in a tree, and then hacking at it with its strong bill.
The list of species below, all in the genus ''Sitta'' (Linnaeus, 1758), is probably the maximum. Some taxonomists consider that some of the indicated species are in fact conspecific.
