The Persian nuthatch [2] or the eastern rock-nuthatch (Sitta tephronota) is a species of bird in the family Sittidae. It is found in Afghanistan, Armenia, Azerbaijan, Georgia, India, Iran, Iraq, Kazakhstan, Pakistan, Russia, Tajikistan, Turkey, and Turkmenistan.
The nuthatches constitute a genus, Sitta, of small passerine birds belonging to the family Sittidae. Characterised by large heads, short tails, and powerful bills and feet, nuthatches advertise their territory using loud, simple songs. Most species exhibit grey or bluish upperparts and a black eye stripe.
The Eurasian nuthatch or wood nuthatch is a small passerine bird found throughout the Palearctic and in Europe. Like other nuthatches, it is a short-tailed bird with a long bill, blue-grey 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; birds in the west of the range have orange-buff underparts and a white throat, those in Russia have whitish underparts, and those in the east have a similar appearance to European birds, but lack the white throat.
The beautiful nuthatch is a bird species in the family Sittidae, collectively known as nuthatches. It is a large nuthatch, measuring 16.5 underparts are orange, and the eyebrow and throat are ochre. An irregular, dark eyestripe highlights its eye. S. formosa's ecology is not fully described, but it is known to feed on small insects and larvae found on the trunks and epiphyte-covered branches of trees in its range. Reproduction takes place from April to May; the nest is placed in the hole of an oak, rhododendron, or other large tree. The nest is made of plant material and fur in which the bird typically lays four to six eggs.
The white-breasted nuthatch is a species of bird in the nuthatch family Sittidae. It is a medium-sized nuthatch, measuring approximately 15.5 cm (6.1 in) in length. Coloration varies somewhat along the species' range, but the upperparts are light blue-gray, with a black crown and nape in males, while females have a dark gray crown. The underparts are whitish, with a reddish tinge on the lower abdomen. The white-breasted nuthatch is a noisy bird. It has a nasal voice and often utters little cries or vocalizations, often composed of repetitions of small invariant whistles. In summer, it is an exclusively insectivorous bird, consuming a wide range of arthropods, but in winter its diet consists mainly of seeds. The nest is located in the cavity of a tree. The clutch consists of five to nine eggs, incubated for two weeks by the female, who is fed by the male. The two adults then feed the young until they fledge, and for a few weeks after that.
The red-breasted nuthatch is a small songbird. The adult has blue-grey upperparts with cinnamon underparts, a white throat and face with a black stripe through the eyes, a straight grey bill and a black crown. Its call, which has been likened to a tin trumpet, is high-pitched and nasal. It breeds in coniferous forests across Canada, Alaska and the northeastern and western United States. Though often a permanent resident, it regularly irrupts further south if its food supply fails. There are records of vagrants occurring as far south as the Gulf Coast and northern Mexico. It forages on the trunks and large branches of trees, often descending head first, sometimes catching insects in flight. It eats mainly insects and seeds, especially from conifers. It excavates its nest in dead wood, often close to the ground, smearing the entrance with pitch.
The Algerian nuthatch is a species of bird in the nuthatch family Sittidae. It is a medium-sized nuthatch, measuring between 11.5 cm (4.5 in) and 12.5 cm (4.9 in). The upperparts are bluish gray. The male can be distinguished from the female by the black front of its crown. The species is sedentary; it feeds on arthropods in summer and on seeds in winter. The breeding season takes place around May–June. The nest, built in a hole of tree, shelters a laying of three or four eggs, brooded by the female. The chicks are fed by both parents.
The western rock nuthatch is a small passerine bird which breeds from Croatia east through Greece and Turkey to Iran. This nuthatch is largely resident apart from some post-breeding dispersal. The eastern rock nuthatch Sitta tephronota is a separate species, which occurs further east in south-central Asia.
The pygmy nuthatch is a tiny songbird, about 10 cm (4 in) long and about 10 grams in weight.
The brown-headed nuthatch is a small songbird found endemic to pine forests throughout the Southeastern United States. Genetic analyses indicated low differentiation between northern and southern populations in Florida, but the study also found lower genetic diversity among south Florida populations that may be a result of the increased habitat fragmentation that was documented. The Bahama nuthatch was formerly considered a subspecies, has since been reclassified as its own separate species. Two recent studies assessing vocalizations in Bahama and continental nuthatch populations found important differences. One of the studies also demonstrated that continental and Bahama populations did not respond aggressively to calls of the other population. This type of call-response study is often used to help define cryptic species.
The varied sittella is a small, around 10–11 cm long, songbird native to Australia. It is also known as the Australian nuthatch, orange-winged sittella and the barkpecker.
The blue nuthatch is a bird species in the nuthatch family Sittidae. It is a medium-sized nuthatch, measuring 13.5 cm (5.3 in) in length. The species, which shows slight sexual dimorphism, has dramatic coloration unlike any other member of its genus. Its head is black or blackish-blue dark blue upperparts close to purple with azure feathers. The wings are edged with black. The throat and chest are white or a washed buff color, contrasting with the upperparts and the belly of a very dark blue; the covert feathers are generally clear, blue-gray or purplish.
The Kashmir nuthatch is a species of bird in the family Sittidae. It is found in the northernmost regions of the Indian subcontinent, primarily in the mid-altitudes of the Himalayas. The species ranges across Afghanistan, India, Nepal and Pakistan. The global population size has not been quantified, but the species is described as common in eastern Afghanistan and north-western India, and fairly common in Nepal.
The Indian nuthatch is a species of bird in the family Sittidae. It is found in Bangladesh, India and Nepal.
The white-tailed nuthatch is a species of bird in the family Sittidae. It ranges across the northern and northeastern parts of the Indian Subcontinent, existing mainly in the low-to-middle Himalayas, as well as associated mountain ranges. It is found in Bhutan, India, Laos, Myanmar, Nepal, Tibet and Thailand.
The white-cheeked nuthatch is a species of bird in the family Sittidae. It is found in Afghanistan, Bhutan, India, Nepal, and Pakistan.
The chestnut-vented nuthatch is a species of bird in the nuthatch family Sittidae. It is a medium-sized nuthatch, measuring 12.5–14 cm (4.9–5.5 in) in length. The upperparts are a solid gray blue, with a markedly black loral stripe. The underparts are uniform gray to buff from the throat to belly, with brick red on the flanks. The undertail is white with a rufous border. The chestnut-vented nuthatch utters different kinds of calls, which can sometimes sound like a troglodyte alarm, and its song is a monotonous, stereotypical crackle, typically chichichichi. Its ecology is poorly known, but it probably feeds on small arthropods and seeds, and the breeding season begins between March and May. The nest is typically located in a hole in the trunk of a tree, and the clutch has two to five eggs.
The white-browed nuthatch, also known as the Victoria nuthatch, is a species of bird in the family Sittidae. It is a small nuthatch, measuring 11.5 cm (4.5 in) in length and without sexual dimorphism. Like many other nuthatches, the upperparts are gray-blue, contrasting with white underparts on the throat, cheeks, and breast and orange on the flanks, belly, and lower abdomen. Its white supercilium makes it easy to distinguish it from the white-tailed nuthatch, which is a close species in the systematic and geographical sense. Little is known about its ecology, but it feeds on small insects found among bark and lichens, and breeding occurs around April.
The Siberian Nuthatch is a bird species of the family Sittidae. For a long time considered as a subspecies of the Eurasian nuthatch, it was clearly differentiated in 2006 on the basis of morphological and molecular characters. It is on average larger than the Eurasian nuthatch and also differs in some morphological features such as the shape of its bill, the size of its claws and the color of its underwing and outer rectrices. Its song has also been described as "distinctly different" from that of the Eurasian nuthatch, though without further clarification.
Przevalski's nuthatch, originally given the nomen nudumSitta eckloni, is a bird species in the family Sittidae, collectively known as nuthatches. Long regarded as a subspecies of the white-cheeked nuthatch, it nevertheless differs significantly in morphology and vocalizations. Both S. przewalskii and S. leucopsis have been regarded as closely related to the North American white-breasted nuthatch. It is a medium-sized nuthatch, measuring about 13 cm (5 in) in length. Its upper body is a dark gray-blue or slate color, becoming dark blue-black at the crown. The cheeks and throat are a white buff-orange, turning to a rich cinnamon on the underparts that intensifies in color on the sides of the breast. Vocalizations consist of alternating series of ascending whistles and short notes.
The Bahama nuthatch is a nuthatch species endemic to the pineyards of Grand Bahama island in the Bahamas. It may be extinct as of 2019.
