Abstract

Between September and January of the 2015-16, 2016-17 and 2017-18 breeding seasons, we performed 305 Ad-libitum observations of Thorn-tailed Rayadito (Aphrastura spinicauda) specimens foraging in various treatments of Ñire (Nothofagus antarctica) forest in mid-western Chubut, Argentina. On 3 December 2017 we observed a Thorn-Tailed Rayadito that, while moving between two patches of Ñire affected by moderate firewood extraction, caught an unidentified lepidopteran in flight. This is the first record aerial foraging for the species.
