In the field I believed the Asthenes to be steinbachi due to lack of throat spot on a good view, and extensive rufous edgings to outer rectrices, much more so than shown for orbignyi in Narosky/Yzurieta, although they are depicted as similar in de la Pena and Rumboll. If latter is correct, bird could possibly be orbignyi; close match to some recordings on both XC and Bird Sounds from Southern South America, but those of both species are varied.
