Taxonomic Notes: | Systematists have debated synonymy between viewed olivaceus and xanthorhinus. Based on apparent morphological and ecological separation in local settings, some systematists consider them distinct (Osgood 1943, Patterson et al. 1984, Pearson 1995) whereas others consider olivaceus as a polytypic species, also including southern xanthorhinus, based on broader regional trends of morphological and morphometric variation (Mann 1978, Yañez et al. 1978). Recent work with transects between where Valdivian rainforest (olivaceus morphotype) transitions into Patagonian steppe (xanthorhinus morphotype) have given evidence of demic intergradation, which strongly supports the synonymy argument (Smith et al. 2001, Pearson and Smith 1999). This assessment includes the species known as A. llanoi, A. mansoensis, A. xanthorhinus, A. hershkovitzi and A. markhami. |
Red List Category & Criteria: | Least Concern ver 3.1 |
Year Published: | 2017 |
Date Assessed: | 2017-03-22 |
Assessor(s): | Patterson, B., Pardinas, U. & D'Elia, G. |
Reviewer(s): | Amori, G. |
Justification: This species is listed as Least Concern in because of its wide distribution, presumed large population, occurrence in a number of protected areas, tolerance to some degree of habitat modification, and because it is unlikely to be declining at nearly the rate required to qualify for listing in a threatened category. |
