Origin, geographical range and distribution
The green oropendola species are distributed in Peru, Bolivia, Ecuador, Colombia, Venezuela, Guyana, Suriname, French Guiana and Brazil. Though these species are common in their range, they are patchily distributed.Ecosystem and habitat
The green oropendola species have high forest dependence. They normally occur in altitudes from 0 to 1100 meters.The natural ecosystems and habitats of these oropendola species include tropical and subtropical moist lowland forests, tall humid forests and tropical rainforests.
Diet and feeding behavior
The diet of this green oropendola species consists mainly of invertebrates. Insects like grasshoppers, locusts, crickets, cicadas, aphids, planthoppers and leafhoppers are their primary food.They also feed on figs, fruits and berries. They forage by moving through the forest canopy in flocks. They also glean insects from the branches of trees and from foliage.
Reproduction and breeding habits
The breeding season of these green oropendola species is from February to April in Venezuela and Suriname. The laying season is from July to December in Brazil. Polygamous behavior has been observed in these species.The nesting sites include horizontal branches of tall trees. They are colonial breeders and the nest is a long bag-shaped structure, dangling from the branch of a tree.
Migration and movement patterns
These oropendola species are a non-migratory resident birds. The populations occurring in higher altitudes move to the lower levels in winter.Post breeding, the juveniles may disperse and establish in new locations within the range. Within their range they may make local movements for feeding and breeding.
