The nuthatch family, Sittidae, was described by René-Primevère Lesson in 1828. [3] [4]Sometimes the wallcreeper (Tichodroma muraria), which is restricted to the mountains of southern Eurasia, is placed in the same family as the nuthatches, but in a separate subfamily "Tichodromadinae", in which case the nuthatches are classified in the subfamily "Sittinae".
The white-breasted nuthatch is the only North American nuthatch usually found in deciduous trees; red-breasted, pygmy and brown-headed nuthatches prefer pines. [ 12 ] The presence of mature or decaying trees with holes suitable for nesting is essential, and trees such as oak, beech and hickory are favored in the east since they also provide ...

Like other nuthatches, it is a short-tailed bird with a long bill, blue-gray upperparts and a black eye-stripe. It is a vocal bird with a repeated loud dwip call. There are more than 20 subspecies in three main groups ...
The nuthatches constitute a genus – Sitta – of small passerine birds in the family Sittidae, [3] typified by short, compressed wings and short, square 12-feathered tails, a compact body, longish pointed bills, strong toes with long claws, and behaviorally, by their unique head-first manner of descending tree trunks. Most nuthatches have ...
Like all nuthatches, the red-breasted nuthatch is an acrobatic species, hitching itself up and down tree trunks and branches to look for food. [12] It goes headfirst when climbing down. It can "walk" on the underside of branches. Unlike woodpeckers and creepers, it does not use its tail as a prop while climbing. [17] It tends to forage singly ...

Przevalski's nuthatch (Sitta przewalskii), originally given the nomen nudum Sitta eckloni, is a bird species in the family Sittidae, collectively known as nuthatches.Long regarded as a subspecies of the white-cheeked nuthatch (Sitta leucopsis), it nevertheless differs significantly in morphology and vocalizations.
The velvet-fronted nuthatch (Sitta frontalis) is a small passerine bird in the nuthatch family Sittidae found in southern Asia from Nepal, India, Sri Lanka and Bangladesh east to south China and Indonesia. Like other nuthatches, it feeds on insects in the bark of trees, foraging on the trunks and branches and their strongly clawed toes allow ...
