Typical Environment
Found across the Pampas and adjacent lowlands of Argentina, Uruguay, southern Brazil, and nearby regions. It favors marshes, wet meadows, reedbeds, rice fields, and damp pastures with standing water or saturated soils. Birds use dense grasses and sedges for cover and nesting sites, often near slow-moving streams or ponds. It also ventures into agricultural edges where water and tall vegetation persist.
