Not recognized (IUCN 3.1)
The Songar tit (Poecile songarus, formerly Parus songarus) is a passerine bird in the tit family. It is the southern counterpart of the willow tit P. montanus, and is often included in it as a subspecies.
The 13 cm long Songar tit has a dark brown cap, blackish bib, rich brown upperparts, white cheeks and cinnamon buff underparts. The sexes are similar, but juveniles are somewhat duller.
The most common call is a nasal zee, zee, zee, but the notes of the bird evidently vary considerably
The Songar tit usually excavates its own nesting hole, often in a rotten stump or in a tree, more or less decayed. Most nests examined are cups of felted material, such as fur, hair and wood chips, but feathers are sometimes used. The number of eggs is from five to six, white with small reddish spots or blotches.
There are four subspecies (Harrap & Quinn 1996):
- Poecile songarus songarus (Severtsov, 1873). Tian Shan mountains.
- Poecile songarus affinis (Przevalski, 1876). North-central China.
- Poecile songarus stoetzneri (O. Kleinschmidt, 1921). Northeastern China.
- Poecile songarus weigoldicus (O. Kleinschmidt, 1921). Southwestern China.
Of these, recent genetic evidence suggests that the first three are best included in P. montanus, with only the last being genetically distinct (del Hoyo et al. 2007).
