Creamy-crested Spinetail Cranioleuca albicapilla

Small, long-tailed bird with a pale head. Light brown, with reddish tail and shoulder patch and pale crown and throat. Found in semi-humid shrubby areas at high elevations, especially along streams, where it forages singly or in pairs low in dense vegetation. Listen for its squeaky song, a choppy, accelerating series of high notes.
