The moriche oriole (Icterus cayanensis chrysocephalus) is a passerine bird in the New World family Icteridae. It is unrelated to Old World orioles (family Oriolidae). It is a breeding resident in the tropics of eastern South America. This bird is noted for its close association with the palm Mauritia flexuosa (moriche, buriti, ita, ité, etc.). The song of the moriche oriole is a squeaky whistling heaaa-wheeooo-heaaa. This is an often-conspicuous species near its favoured tree, and usually occurs singly or in pairs.
