Get to Know the Crested Oropendola
Crested Oropendolas are gregarious birds that flock together in the winter and roost communally in enormous numbers. In the breeding season, they nest in colonies to protect themselves from predators. It is common to see both sexes of the Crested Oropendola sing or call, to attract members of the opposite sex for breeding.
Female Oropendolas weave spherical nests out of grass and palm fibers. These nests measure from three to six feet in length.
Each colony has a dominant male, which mates with most of the females following an elaborate bowing display.

Crested Oropendolas feed on insects, seeds, grain, fruits, and nectar. The Crested Oropendola’s breeding season is during the months of November through April. They breed in large colonies of 100 or more to scare off predators. Males show off the color of their feathers and sing to attract as many females as they can.

Reproduction & Growth
Female Oropendolas weave spherical nests out of grass and palm fibers. These nests measure from three to six feet in length. The nests can be found in the branches of high isolated trees. Male Oropendolas help to protect these nests during the growth of their offspring.
Crested Oropendolas are not endangered. However, they do not have an enormous population because their tropical habitat is being reduced every year by human development.
