Cinereous Harrier Circus cinereus


The Cinereous Harrier is the common South American harrier of Andean grasslands, coastal marshes, pastures, wetlands and the shrub-steppe of Patagonia. It occurs from the Andes of Colombia south to Tierra del Fuego and east into the lowland plains of Bolivia and Argentina. Though the only harrier over the majority of its range, it overlaps with the much darker Long-winged Harrier in south central South America, where their degree of ecological separation is unknown. The Cinereous Harrier feeds predominantly on birds but also small reptiles and mammals, though the ratio of these food items depends on locality; harriers in Patagonia seldom take avian prey.
