Mexican Chickadee (Poecile sclateri)


Taxonomy

French: Mésange grise German: Grauflankenmeise Spanish: Carbonero mexicano
Taxonomy:

P[arus]. sclateri

, 1897,

El Jacale, southern Mexico

.

Initial DNA analysis suggested close relationship to P. hudsonicus and P. rufescens#R, whereas more recent study indicates that closest relative of present species is P. cinctus#R. Geographical variation largely clinal, size decreasing N to S; races poorly defined, and intergrade widely. Species perhaps better treated as monotypic, as differences slight and perhaps inconstant. Four subspecies currently recognized.
