Like the Green oropendola, this species comes from Northeastern South America. Its icy blue eyes contrast with its black feathers. The yellow tail feathers of oropendolas are prized by Native Americans for use in elaborate head dresses. Oropendolas prefer building their nests over water, and several can always be observed over the Orinoco crocodiles. Both Green and Crested oropendolas have bred at the DWA.
