Желтобородая иглохвостка Schoeniophylax phryganophilus

Unique spinetail with a rather long spiky tail and a yellow and black chin. The Chotoy Spinetail also has a rusty crown and shoulders, a buffy breast and flanks, dark streaks on the back, and a white eyebrow. Found in open areas with scattered trees and shrubs, riparian thickets, and second growth. Sings a series of low-pitched “cho” notes that accelerate toward the end.
