Перуанская курутия Cranioleuca marcapatae

Fairly small, long-tailed bird found in a small range in the Peruvian Andes. Reddish brown above, pale tan below, with a pale eyebrow edged in black and a variably colored crown. In the eastern part of its range, the crown is reddish brown; in its northwestern populations, the crown is creamy white. Has a bolder whitish throat and eyebrow than the similar Ash-browed Spinetail, which is typically found at lower elevations. Marcapata Spinetail forages in low vegetation in cloud forest, especially in thick bamboo. Listen for its song, a descending series of staccato, metallic notes.
