Identification
Long known to ornithologists as something different (and informally called “Millpo Tapaculo”), this bird was finally described as a new species in 2020. It inhabits grassy, rock-strewn areas above tree line at high elevations in the eastern Andes of central Peru. Plumage is mainly gray with tan rear parts that are faintly barred, and it sometimes shows a faint, whitish eyebrow; female is browner than male. Similar in appearance to several other tapaculos, and best identified by range and voice. Song, often given from atop a rock, is a seemingly endless series of raspy chip notes.
