The Corsican nuthatch is a small bird species native to the forests of Corsica and Sardinia. It is characterized by its distinctive blue-gray plumage, white underparts, and a black cap on its head. This bird primarily inhabits coniferous forests, where it forages for insects, seeds, and nuts. This species is known for its unique nesting behavior, often creating nests in tree cavities. The Corsican nuthatch is a non-migratory bird, meaning it stays in its habitat year-round. Due to habitat loss and other environmental pressures, it is considered vulnerable, making conservation efforts important for its survival.
