Red-shouldered Blackbird

Agelaius assimilis

The Red-shouldered Blackbird (Agelaius assimilis) is a medium-sized blackbird found in South America. The male is glossy black with bright red shoulder patches, while the female is brown with streaked underparts. These birds are often found in marshes, wetlands, and grasslands, where they forage for insects and seeds. They build cup-shaped nests among reeds or grasses. Red-shouldered Blackbirds are known for their distinctive calls and are often seen in large flocks during the breeding season. While their populations are currently stable, they face threats from habitat loss and pollution.
