Yungas Sparrow Rhynchospiza dabbenei



Taxonomy

Taxonomic note
Previously lumped with R. strigiceps as R. strigiceps (del Hoyo and Collar 2016). Areta et al. (2019) split dabbenei from strigiceps on the basis of major differences in song and call, difference in habitat and pale blue vs brown marked eggs. Furthermore specimen evidence suggests dabbenei differs from strigiceps by its conspicuous chestnut carpal patch, blackish loral area, slightly darker chestnut crown-stripes, broader and richer buffy-rufous edges to wing and tail feathers and clearly much larger size. The more prominent black malar stripe reported by Areta et al. (2019) is not apparent. Monotypic.

Population justification: The global population size has not been quantified, but this species is described as common (García and Jaramillo 2021).

Trend justification: The species occurs in a variety of open and forested habitats (García and Jaramillo 2021); no threats are known to the species. Therefore, in the absence of evidence for any declines or substantial threats, the population is suspected to be stable.
