Pantanos de Villa Wildlife Refuge, Protected wetland area in Chorrillos, Peru.

Pantanos de Villa Wildlife Refuge is a protected area of brackish lagoons and marshes in Chorrillos, within the city of Lima, Peru, covering 263.27 hectares. Its open grey-blue water is edged by tall green reeds with brown seed heads, and a single weathered, splintered tree trunk rises from the water, where a small crested bird sometimes perches.

The area received protection status in 1977 under city parks management and gained international Ramsar recognition in 1997. This second step committed Peru to maintaining the ecological health of the marshes despite surrounding urban growth.

The name reflects Villa, the district at the southern edge of the city where brackish springs feed the marshes. Local school groups often visit during field trips to use the observation towers and watch waterbirds searching for food in the shallow lagoons.

Birdwatching peaks in summer, from December to March, when migratory species are present. Access is via Avenida Defensores del Morro, the former Avenida Huaylas, which crosses the marshes and splits them into two roughly equal parts; the Huaylas bridge interchange is the recommended approach. PROHVILLA offers three marked routes, two lasting one hour and one 45 minutes.

The broken trunk standing in the open water is a favourite perch for a small crested bird, and the refuge's bird list reaches 210 species, with 30 of them migratory, arriving periodically from Alaska and the Andean region. A 2004–2007 study confirmed 58 resident or migrant species and estimated up to 56 more could be found.
