Often, it is still placed in the genus Parus with most other tits, but mtDNA cytochrome b sequence data and morphology suggest that separating Poecile more adequately expresses these birds' relationships (Gill et al., 2005).

Polytypic. Consists of four subspecies.


Wooded highlands.



The nest is constructed by the female and consists of grasses, moss, strips of bark, and is lined with animal fur. 5 - 8 ovate white eggs, marked with fine reddish brown spots, are laid and are incubated for 11 to 14 days by the female. The young fledge in 18 to 21 days.
