Crested oropendola

The crested oropendola, also known as the Suriname crested oropendola or cornbird, is a captivating bird native to the tropical regions of South America, stretching from Panama and Colombia down to northern Argentina, and including the islands of Trinidad and Tobago. This vibrant species is a frequent sight in lowland areas, often observed foraging in trees for insects, fruit, and nectar.

Adult male crested oropendolas are remarkable, characterized by their mostly black plumage, a chestnut-colored rump, and a bright yellow tail. Females appear similar but are smaller and lack the distinctive crest that males exhibit.

There are four subspecies of the crested oropendola, each with subtle differences in plumage. These birds favor forest edges and clearings, where they construct their unique hanging woven nests high in the trees. The crested oropendola practices a colonial breeding system, where a dominant male mates with multiple females, and each nest typically contains two eggs.

One of the standout features of the crested oropendola is its distinctive songs and calls, which contribute to the rich soundscape of their tropical habitats. Interestingly, these birds also serve as hosts to the Acanthocephalan intestinal parasite, Apororhynchus aculeatus.
