Tits and Chickadees (Paridae)

Mexican Chickadee (Poecile sclateri) - HBW 12, p. 715

French: Mésange grise German: Grauflankenmeise Spanish: Carbonero Mexicano
Other common names: Grey-sided Chickadee

Taxonomy: P[arus] sclateri O. Kleinschmidt, 1897, El Jacale, southern Mexico.
Until recently present genus normally subsumed into a broad Parus, and many authors still prefer that treatment. Genus normally treated as feminine, but no evidence in original description or elsewhere justifies this, so genus is masculine by default. Has been placed in a superspecies with P. gambeli, sometimes including also P. montanus, P. carolinensis and P. atricapillus; DNA analysis, however, suggests closer relationship to P. hudsonicus and P. rufescens; further research required. Geographical variation largely clinal, size decreasing from.. View all taxonomy...

Taxonomy: P[arus] sclateri O. Kleinschmidt, 1897, El Jacale, southern Mexico.
Until recently present genus normally subsumed into a broad Parus, and many authors still prefer that treatment. Genus normally treated as feminine, but no evidence in original description or elsewhere justifies this, so genus is masculine by default. Has been placed in a superspecies with P. gambeli, sometimes including also P. montanus, P. carolinensis and P. atricapillus; DNA analysis, however, suggests closer relationship to P. hudsonicus and P. rufescens; further research required. Geographical variation largely clinal, size decreasing from N to S; races poorly defined, and intergrade widely. Species possibly better treated as monotypic, as differences among populations slight and perhaps not sufficiently constant to warrant naming of races. Four subspecies currently recognized.

Subspecies and Distribution:

  • eidos (J. L. Peters, 1927) - extreme S USA (SE Arizona, SW New Mexico) and N Mexico (N & C Sierra Madre).
  • sclateri (O. Kleinschmidt, 1897) - C Mexico (C & S Sierra Madre).
  • garzai (A. R. Phillips, 1986) - NE Mexico.
  • rayi (A. H. Miller & Storer, 1950) - S Mexico.
