Olivbuschammer Arremon castaneiceps

A shy, stream-loving, finch-like bird of Andean cloud forest. Plumage is olive with a chestnut crown and gray face and throat. Sexes look alike. Single birds or pairs stay low in dark gullies and ravines, usually near running water but occasionally away from it. Sings a very high-pitched, squeaky song that can be heard over the roar of rushing torrents.
