The sexes of this icterid are very different in size: the male is 52 cm long and weighs 550 g ; the smaller female is 41 cm long and weighs 260 g . Confusingly, the name Olive Oropendola has sometimes been used for this combined species, despite the fact that the nominate subspecies has no olive to its plumage, as its head and chest are black . The back, wings and belly of this large oropendola are brown, the outer rectrices are yellow , the bare facial skin is pink, the eyes are brown, and the bill is black with an orange tip. The superficially similar Green Oropendola has an olive back and wing-coverts, lacks extensive bare facial-skin, has a pale bill with an orange tip, and blue eyes.
The Para Oropendola is classified as Least Concern. Does not qualify for a more at risk category. Widespread and abundant taxa are included in this category.
