The Yellow-Shouldered Blackbird is a striking bird native to Puerto Rico. It has glossy black plumage with a bright yellow patch on each shoulder, which stands out in flight. Males and females look similar, though males are slightly larger. Unlike some blackbirds, this species has a relatively slender body and a sharp, pointed beak.
This blackbird prefers coastal mangroves, forests, and open fields. It is a social bird, often seen in small flocks foraging for insects, seeds, and fruit. It has a varied vocal range, including whistles and chattering calls. During breeding season, it builds cup-shaped nests in mangroves or in tree hollows.
The Yellow-Shouldered Blackbird is endangered due to habitat loss and nest predation by the invasive Shiny Cowbird, which lays its eggs in the blackbird’s nest. Conservation efforts focus on protecting nesting sites and controlling cowbird populations. Though challenges remain, ongoing work aims to secure the future of this unique island bird.
