Species Description
The Russet-Backed Oropendola is a common and widespread bird of South America, found in wooded habitats in the highlands of the northern and central Andes and Venezuelan Coastal Range, as well as the lowlands of the western Amazon basin. It is a large passerine bird with a pointed bill, which it uses to collect fruit and large insects. The Russet-Backed Oropendola is a very vocal and social bird, nesting colonially; several pairs will build their long, woven basket nests in the same tree. These nests are also often built next to bee and wasp nests, with the proximity to the stinging insects providing some level of protection against predators.
