Ovenbirds (Furnariidae)

Maquis Canastero (Asthenes heterura) - HBW 8, p. 302

French: Synallaxe d’Iquico German: Dornbuschcanastero Spanish: Canastero de Iquico
Other common names: Iquico Canastero

Taxonomy: Siptornis heterura Berlepsch, 1901, Iquico, 4000 m, La Paz, Bolivia.
Considered by various authors to be a race of A. pudibunda, but tail structure differs, or more closely related to and perhaps conspecific with A. ottonis; some have proposed that the three should be treated as forming a superspecies. Others suggest that, on basis of plumage and behavioural similarities (avoidance of cocking tail), closest relative may be A. pyrrholeuca, the two having been confused regularly in the field and as museum specimens. Monotypic.

Distribution: Andes of N Bolivia (S La Paz, Cochabamba, also sight records from Chuquisaca and Tarija) and NW Argentina (Jujuy, Salta, Tucumán).
