This species will also nest in river banks or tree holes and will enlarge its nest hole if it the cavity is too small. 12.5 cm (4.9 in) long, violet-blue above, with lavender cheeks, beige underparts and a whitish throat, bill is red, black patch on forehead. A few nuthatch species have restricted ranges and face threats from deforestation. , A 2006 review of Asian nuthatches suggested that there are still unresolved problems in nuthatch taxonomy and proposed splitting the genus Sitta. Their habit of wedging a large food item in a crevice and then hacking at it with their strong bills gives this group its English name. 143–144 "Yunnan Nuthatch", Harrap & Quinn (1996) pp. The. 12–13 "Species limits", Harrap & Quinn (1996) pp. The eggs are incubated for 12 to 18 days by the female alone, or by both parents, depending on the species. , Members of the nuthatch family live in most of North America and Europe and throughout Asia down to the Wallace Line. The shade of grey upper parts and the darkness of the eye stripe vary between the three subspecies. Red-breasted Nuthatches are mainly birds of coniferous woods and mountains. The underparts are rich rusty-cinnamon, paler in females. Moves up, down, and around tree trunks and branches pulling out insects from bark or seeds from cones.

The nuthatch family, Sittidae, was described by René-Primevère Lesson in 1828. The Cornell Lab will send you updates about birds, birding, and opportunities to help bird conservation. The population of the white-browed nuthatch, estimated at only a few thousand, is decreasing, and no conservation measures are in place. See more images of this species in Macaulay Library. Smithsonian Institution and Lynx Edicions, Washington D.C. and Barcelona, Harrap & Quinn (1996) pp. The only significant migrant is the red-breasted nuthatch, which winters widely across North America, deserting the northernmost parts of its breeding range in Canada; it has been recorded as a vagrant in Bermuda, Iceland and England. Foothills of the Himalayas from northeast India to western. The endangered white-browed nuthatch is found only in the Mount Victoria area of Burma, where forest up to 2,000 m (6,600 ft) above sea level has been almost totally cleared and habitat between 2,000–2,500 m (6,600–8,200 ft) is heavily degraded. , Species boundaries in the nuthatches are difficult to define. Blue-gray above and rusty below. 165–168 "Sulphur-billed Nuthatch", Harrap & Quinn (1996) pp. A frequent visitor at seed and suet feeders. They creep up, down, and sideways without regard for which way is up, and they don’t lean against their tail the way woodpeckers do.  However, the two species of rock nuthatches are not strongly tied to woodlands: they breed on rocky slopes or cliffs, although both move into wooded areas when not breeding. 10.5 cm (4.1 in) long, brown cap with narrow black eye stripe and buff white cheeks, chin, and belly, wings are bluish-grey, small white spot at the nape of the neck. These long-billed, short-tailed songbirds travel through tree canopies with chickadees, kinglets, and woodpeckers but stick to tree trunks and branches, where they search bark furrows for hidden insects.

The red-breasted nuthatch makes the nest secure by daubing sticky conifer resin globules around the entrance, the male applying the resin outside and the female inside. They forage within their territories when breeding, but they may join mixed feeding flocks at other times. It has been described as Certhiops rummeli. 62. Look for them among spruce, fir, pine, hemlock, larch, and western red cedar as well as around aspens and poplars. Nuthatches have big heads, short tails, and powerful bills and feet. The resin may deter predators or competitors (the resident birds avoid the resin by diving straight through the entrance hole). It measured the willingness of males of two species to feed incubating females on the nest when presented with models of a sharp-shinned hawk, which hunts adult nuthatches, or a house wren, which destroys eggs. An intense bundle of energy at your feeder, Red-breasted Nuthatches are tiny, active birds of north woods and western mountains. 125–126 "White-browed Nuthatch", Harrap & Quinn (1996) pp. 150–155 "White-breasted Nuthatch", Harrap & Quinn (1996) pp. Stout, no-necked bird with a long, sharply pointed bill. 11 cm (4.3 in) long, blue-grey upper parts, with reddish underparts, white face with a black eye stripe, white throat, a straight grey bill and a black crown. , The western rock nuthatch builds an elaborate flask-shaped nest from mud, dung and hair or feathers, and decorates the nest's exterior and nearby crevices with feathers and insect wings. 123–125 "White-tailed Nuthatch", Harrap & Quinn (1996) pp. The strength of the association varies from the Corsican nuthatch, which is closely linked with Corsican pine, to the catholic habitat of the Eurasian nuthatch, which prefers deciduous or mixed woods but breeds in coniferous forests in the north of its extensive range. Nuthatches(Order: Passeriformes, Family:Sittidae). 144–148 "Red-breasted Nuthatch", Harrap & Quinn (1996) pp. Their breeding songs tend to be simple and often identical to their contact calls but longer in duration. The sexes look similar, but may differ in underpart colouration, especially on the rear flanks and under the tail.
