Kingdom Phylum Class Order Family
ANIMALIA CHORDATA AVES PASSERIFORMES PARIDAE

Scientific Name: Parus rufescens
Species Authority: Townsend, 1837
Common Name/s:
English – Chestnut-backed Chickadee
Taxonomic Notes: All Parus species (Sibley and Monroe 1990, 1993) are retained in the genus Parus contra AOU who place all North American Parus species in the genus Poecile including the holarctic P. cinctus. The BirdLife Taxonomic Working Group is aware that phylogenetic analyses have been published which have proposed generic rearrangements which may affect this species, but prefers to wait until work by other taxonomists reveals how these changes affect the entire groups involved.

Red List Category & Criteria: Least Concern ver 3.1
Year Published: 2012

Justification:
This species has a very large range, and hence does not approach the thresholds for Vulnerable under the range size criterion (Extent of Occurrence <20,000 km2 combined with a declining or fluctuating range size, habitat extent/quality, or population size and a small number of locations or severe fragmentation). The population trend appears to be increasing, and hence the species does not approach the thresholds for Vulnerable under the population trend criterion (>30% decline over ten years or three generations). The population size is extremely large, and hence does not approach the thresholds for Vulnerable under the population size criterion (<10,000 mature individuals with a continuing decline estimated to be >10% in ten years or three generations, or with a specified population structure). For these reasons the species is evaluated as Least Concern.
