They were formerly considered to be one species, but are now normally split into three[12] and comprise a superspecies along with the Krüper's and Algerian nuthatch. Nuthatches have blue-grey backs (violet-blue in some Asian species, which also have red or yellow bills) and white underparts, which are variably tinted with buff, orange, rufous or lilac. Size: length 16.5 in (42 cm), wingspan 29 in (74 cm) Habitat: forest, subalpine [3][8], The nuthatches are all in the genus Sitta Linnaeus, 1758,[9] a name derived from sittē, Ancient Greek for this bird. Size: length 9.25 in (23.5 cm), wingspan 15 in (38 cm) S&L: MarcWildPassion: 24-Nov-2007 11:42: Very nice gallerie of Bird!V: meekam tam: 24-Nov-2007 05:27: Beautiful gallery!

The law reduced bureaucracy and made it easier for developers to build tourism facilities and summer houses in the coastal zone where woodland loss is a growing problem for the nuthatch.

13 cm (5.1 in) long, colours vary between the subspecies. [65] Nuthatches and other small woodland birds share the same predators: accipiters, owls, squirrels and woodpeckers. [19] Two fossil species have been described in the genus Sitta: S. cuvieri Gervais, 1852 and S. senogalliensis Portis, 1888, but probably not belong to nuthatches.

[11] Species boundaries in the nuthatches are difficult to define. Smithsonian Institution and Lynx Edicions, Washington D.C. and Barcelona, Harrap & Quinn (1996) pp. Size: lenth 5.25 in (13 cm), wingspan 7.75 in (19.6 cm)

[61], Nuthatches forage along tree trunks and branches and are members of the same feeding guild as woodpeckers.

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. 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. 155–158 "Western Rock Nuthatch", Harrap & Quinn (1996) pp. Seasons: common year-round 109–114 "Eurasian Nuthatch", Harrap & Quinn (1996) pp. Their breeding songs tend to be simple and often identical to their contact calls but longer in duration. Brown Creeper Seasons: common year-round In some species the lining consists of small woody objects such as bark flakes and seed husks, while in others it includes the moss, grass, hair and feathers typical of passerine birds. Habitat: forest 14 cm (5.5 in) long, mostly greyish upper parts, reddish underparts with a paler throat and chin. The Yunnan nuthatch can cope with some tree loss, since it prefers open pine woodland, but although still locally common, it has disappeared from several of the areas in which it was recorded in the early 20th century. [6] The red-breasted nuthatch, which coexists with the black-capped chickadee throughout much of its range, is able to understand the latter species' calls.

143–144 "Yunnan Nuthatch", Harrap & Quinn (1996) pp. These small birds have blue backs and pale orange bellies (brighter in males), with distinctive black and white stripes on the face. Nuthatches are omnivorous, eating mostly insects, nuts, and seeds. 12–13 "Species limits", Harrap & Quinn (1996) pp. 1402–1404 "Nuthatch", Snow & Perrins (1998) pp. Its nest can be quite small but may weigh up to 32 kg (70 lb). [54][55], Nuthatches prefer a fairly temperate climate; northern species live near sea level whereas those further south are found in cooler highland habitats. [74][75] The Algerian nuthatch is found in only four areas of Algeria, and it is possible that the total population does not exceed 1,000 birds. This species will also nest in river banks or tree holes and will enlarge its nest hole if it the cavity is too small. 16–17 "Family Introduction", Harrap & Quinn (1996) pp. For the ancient capital of Sittacene, see, Cracraft, J.; Barker, F. Keith; Braun, M. J.; Harshman, J.; Dyke, G.; Feinstein, J.; Stanley, S.; Cibois, A.; Schikler, P.; Beresford, P.; García-Moreno, J.; Sorenson, M. D.; Yuri, T.; Mindell. Habitat: forest, subalpine

Seasons: common year-round The nest site is usually above 15 feet up, and at times as high as 60 feet. Habitat: forest, subalpine The Ripley guide.

The population of the white-browed nuthatch, estimated at only a few thousand, is decreasing, and no conservation measures are in place.

Eurasian and red-breasted nuthatches are lowland birds in the north of their extensive ranges, but breed in the mountains further south; for example, Eurasian nuthatch, which breeds where the July temperature range is 16–27 °C (61–81 °F), is found near sea level in Northern Europe, but between 1,750 and 1,850 m (5,740 and 6,070 ft) altitude in Morocco. D. P. (2004) "Phylogenetic relationships among modern birds (Neornithes): Toward an avian tree of life." Seasons: common year-round The resin may deter predators or competitors (the resident birds avoid the resin by diving straight through the entrance hole). Hairy Woodpecker, Northern Flicker 98304. [42] The eastern rock nuthatch builds a similar but less complex structure across the entrance to a cavity. 164–165 "Yellow-billed Nuthatch", Harrap & Quinn (1996) pp.

Nuthatches use their feet to climb trees, bracing with one foot placed lower than the other. Northern Flicker Calls [42][43] European nuthatches have been found to avoid using their caches during benign conditions in order to save them for harsher times.[71]. [24], Members of the nuthatch family live in most of North America and Europe and throughout Asia down to the Wallace Line.

Wings have white coverts and tails have a white stripe down the center. Juveniles and first-year birds can be almost indistinguishable from adults. White-breasted Nuthatches nest in natural cavities or knotholes, woodpecker holes, or sometimes in nest boxes. Size: length 8.5 in (21.6 cm), wingspan 16 in (40.6 cm) The shade of grey upper parts and the darkness of the eye stripe vary between the three subspecies. This would be a good way to compare the different feet and how they are designed to be used. Sphyrapicus ruber Male has a black crown and eye stripe separated by a white. [13], The Eurasian, chestnut-vented, Kashmir and chestnut-bellied nuthatches form another superspecies and replace each other geographically across Asia. Red-breasted Sapsuckers do not actually drink sap, but drill holes to catch insects in the tree sap. Some nuthatches, such as the Eurasian nuthatch and the North American species, have extensive ranges and large populations, and few conservation problems,[72] although locally they may be affected by woodland fragmentation. They have long, sturdy, pointed bills and strong toes with long claws. [20], Nuthatches are compact birds with short legs, compressed wings, and square 12-feathered tails.

Western populations of Northern Flickers have grey heads, with brown crowns. Red-breasted Sapsuckers have red heads and breasts, with yellow-grey bellies. The. [50][51] 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. The resemblances arose via convergent evolution to fill an ecological niche. [15] Mitochondrial DNA studies have demonstrated that the white-breasted northern subspecies of Eurasian nuthatch, S. (europea) arctica, is distinctive,[16] and also a possible candidate for full species status.

This morning I went out to film jays at a site in the North Esk Valley in Midlothian, Scotland. [37], Most nuthatches are woodland birds and the majority are found in coniferous or other evergreen forests, although each species has a preference for a particular tree type.

[14][30], Members of the red-breasted nuthatch superspecies excavate their own tree holes, although most other nuthatches use natural holes or old woodpecker nests. 172–173 "Beautiful Nuthatch", Snow & Perrins (1998) pp.
