Description
The adult male is 12 cm (4.7 in) long and weighs 11.8–14.4 g (0.42–0.51 oz). It has a black crown and eyestripe separated by a white supercilium. The upperparts are blue-grey and the throat and underparts are greyish-buff. The flight feathers are dark grey-brown fringed with blue-grey. The bill is black to grey-brown becoming pale grey on the base of the lower mandible, the iris is dark brown and the legs and feet are grey-brown or greyish. The female is similar to the male but has a grey crown and eyestripe. Young birds are duller versions of the adults. The Corsican nuthatch has a pu-pu-pu call and a trilled hididididididi song. Adults have a complete moult after breeding. Juveniles have a partial moult beginning about 8 weeks after fledging. The adult annual survival rate for male birds is 62 per cent which corresponds to an average lifetime of 2 years and 1 month. The maximum recorded age is 5 years and 7 months.

Feeding Habits
Corsican Nuthatch primarily feeds on Corsican pine seeds in winter, extracted with its long bill and hoarded in bark crevices; during bad weather, it recovers stored seeds. In spring, corsican Nuthatch's diet shifts to arthropods, including beetles and insects, evidenced by gizzard contents. Its distinctive ability to climb down trees aids in foraging, and it occasionally flycatches.
Habitat
Corsican Nuthatch is typically found in mature, unmanaged forests dominated by Corsican pine, with a preference for areas with abundant standing deadwood and clearings. These habitats generally have heavy autumn and winter rainfall with drier summers. Corsican Nuthatch also inhabits forests with a mix of other tree species, but at lower densities, and may disperse to different woodland types during winter, still favoring pine-rich areas.

Species Status
The population is about 2,000 pairs; the main threats are fire, which destroys the habitat, and predation by great spotted woodpeckers. Since 2010 this bird is considered as a vulnerable species.
