About the species

The Long-winged Harrier is a striking raptor found across southern South America, including the open grasslands and wetlands of Patagonia. Recognizable by its long, slender wings and tail, this bird is adapted for low, slow flight as it hunts. Adults are mostly black with a white rump and underparts, while juveniles are browner. The species is secretive and often solitary, making it a rare but exciting sight for birdwatchers. Its hunting style involves gliding just above the ground, using keen eyesight to spot small mammals, birds, and amphibians. The Long-winged Harrier plays an important role in controlling populations of rodents and other small animals in its ecosystem.

Habitat

Prefers open wetlands, marshes, pampas, and grasslands, especially near water in southern South America.

Foraging

Hunts by flying low over open ground, searching for small mammals, birds, and amphibians.
