Ovenbirds (Furnariidae)

Mouse-colored Thistletail (Schizoeaca griseomurina) - HBW 8, p. 271

French: Synallaxe souris German: Olivrücken-Distelschwanz Spanish: Piscuiz Ratón

Taxonomy: Synallaxis griseo-murina P. L. Sclater, 1882, San Lucas, Loja, Ecuador.
Forms a superspecies with other members of genus, as a series of non-overlapping mountain-top replacements, and all sometimes considered conspecific; their vocalizations seem fairly close, but plumage patterns differ to an extent not found within individual species-level taxa in Furnariidae. Present species is almost certainly paraphyletic with regard to S. fuliginosa (which brackets its distribution to N and S); probably closest to latter’s nominate race, sharing with it the feature of a white eyering. Monotypic.

Distribution: Andes of S Ecuador (S from Azuay and Morona-Santiago) and N Peru (Piura, Cajamarca).
