The willow tit is a tit 11.5cm long with a wingspan of 17–20.5cm, weighing around 11g. The plumage is grey-brown and off-white with a long dull black cap that descends to the mantle and a black bib. It has a large head and thin bill, white sides of the face, a grey-brown back and buff underparts (Wikipedia, general species account).
It is a widespread and common resident breeder throughout temperate and subarctic Europe and across the Palearctic, and more of a conifer specialist than the closely related marsh tit. The clutch is typically six to nine eggs, laid daily. The source does not describe its status in China (Wikipedia, general species account).
