Least Concern

Olive Spinetail (Cranioleuca obsoleta)


French: Synallaxe olive German: Braunoliv-Baumschlüpfer Spanish: Curutié oliváceo

Leptoxyura obsoleta

Genetic analysis#R indicates that this species is closely related to C. pallida and C. pyrrhophia; apparently hybridizes with latter, and in past sometimes suggested as being conspecific, but very little evidence of introgression#R.

E Paraguay, SE Brazil (S São Paulo S to S Rio Grande do Sul) and NE Argentina (Misiones, N Corrientes).
