About

The red-shouldered blackbird (Agelaius assimilis), known in Cuban Spanish as mayito de la ciénaga (swamp mayito) or sargento cubano (Cuban sergeant) and turpial de hombros rojos (red-shouldered troupial), is a species of passerine bird in the family Icteridae endemic to Cuba. It is similar to other species in the genus Agelaius, but recent research has established it as a separate species from the closely related red-winged blackbird (Agelaius phoeniceus).
