The crested oropendola, also known as the Suriname crested oropendola or the cornbird, is a New World tropical icterid bird. It is a resident breeder in lowland South America east of the Andes, from Panama and Colombia south to northern Argentina, as well as on Trinidad and Tobago. If the genus Gymnostinax for the Montezuma oropendola and its closest relatives were considered valid, this species would probably belong in that genus.
Region
Tropical lowland South America and Panama, including Trinidad and Tobago
Typical Environment
Occurs east of the Andes from Panama and northern Colombia through Venezuela, the Guianas, and much of Amazonia south to northern Argentina, and on Trinidad and Tobago. Prefers lowland and foothill habitats including rainforest edges, riparian gallery forest, second growth, and wooded savannas. Frequently uses human-modified landscapes such as plantations, shade coffee and cacao, and scattered tall trees in pastures. Colonies are typically established in prominent trees in open areas or along rivers where long nests hang freely.

This large icterid is famous for its colonial nesting, weaving long pendulous nests that can exceed a meter in length, often clustered high in isolated trees. Males perform dramatic bowing displays while giving a bubbling, gurgling song. It is commonly called the cornbird in parts of its range for occasionally raiding maize fields. Colonies are sometimes placed near wasp nests, which may help deter predators.

Temperament
social and active
Flight Pattern
strong flier with direct flight and short glides between trees
Social Behavior
Highly colonial breeder; large groups build many long, pendulous nests in the same tree. Males are polygynous and defend display perches within the colony, performing elaborate bowing displays. Nests are woven from plant fibers and often placed over water or in isolated trees to reduce predation.
Migratory Pattern
Resident
Song Description
Males produce a distinctive liquid, bubbling gurgle followed by metallic clicks and rattles during display. Calls include sharp chatters and nasal notes used to keep contact within flocks.
