Chinese Nuthatch

Overview

The Chinese nuthatch, also known as the snowy-browed nuthatch (Sitta villosa), is a small species of bird in the family Sittidae. It is classified as 'Least Concern' by the IUCN Red List due to its large range and stable population numbers.

Identification

• Small bird measuring 11.5 cm (4.5 in) in length with blue-grey upperparts and underparts ranging from dull buff-grey to cinnamon-orange.
• Marked sexual dimorphism: adult males have a very black crown, while females have a blue-grey or dark grey crown.
• Distinctive dark grey eyestripe topped by a clear white supercilium, with white cheeks.
• Song is variable, consisting of repetitions of small invariant whistles, or harsh calls reminiscent of a jay.

Habitat

The species inhabits coniferous forests, such as Pinus and Picea, sometimes mixed with oaks and birches, across central and northeast China, Korea, and the extreme southeast of Russia. In the Korean peninsula, it is closely associated with Japanese Red Pine (Pinus densiflora) forests. It has also been reported in high-altitude Siberian larch forests, though these records remain debated.

Diet

In summer, the diet consists almost exclusively of insects, including beetles, Hymenoptera, and flies, which are sometimes captured in flight or held with the legs and shredded with the bill. In winter, the bird primarily feeds on nuts, seeds, and tree fruits, often joining mixed-species foraging flocks. The Chinese nuthatch also stores food for later use.

Did you know?

A 2009 study predicted that climate change could cause the distribution of the Chinese nuthatch to decrease by 79.8–80.4% between 2040 and 2069. Despite these projections, the species remains classified as 'Least Concern' due to its current extensive range.
