Two-banded Plover in South America

Scientific name: Charadrius falklandicus

Family: Charadriidae

Spanish name: Chorlito doble collar

Migration: Patagonian (Neotropical) migrant

Population estimate: 25,000-100,000 ([1])

Trend: Stable ([1])

Ramsar Criterion 6 (1% level): 1,000 ([1])

IUCN Conservation status: Not known to have unfavourable conservation status

 

Distribution and abundances

Endemic of South America, this Patagonian migrant distributes south of the continent to Tierra del Fuego, breeding mainly within southern Argentina and Chile and migrating to north of Chile and Argentina, Uruguay and southern Brazil for wintering. A separate and sedentary population is restricted to the Malvinas / Falkland Islands. Recorded in coastal and inland wetlands, but with the highest abundances along the coast (link to Abundances map). Sites along the Atlantic coast reaching the 1% threshold (Ramsar Convention Criterion No. 6) are: Bahía San Sebastián, Río Grande, Estuario del Río Deseado, Punta Medanosa, Bahía Bustamante, Bahía San Antonio, Albúfera Mar Chiquita and Bahía Samborombón in Argentina and Lagoa do Peixe in Brazil.

 

Migration and seasonality

Breeds between September and November along sandy or gravely beaches in the coast and in lagoons and rivers within the Patagonian steppe, up to 1.200 m on the foothills of the Andes in southern Argentina. After the breeding season, most birds migrate north reaching northern Argentina (coast of Buenos Aires province, but also reaching Entre Ríos, Córdoba, Santa Fe and Catamarca provinces), the coasts of Uruguay and Rio Grande do Sul in Brazil, and the region of Antofagasta in Chile. In spite of the scarce information about the migration of this plover, it seems to occur inland along the East and West Patagonia Routes, as well as along the Atlantic and Pacific Flyways. Part of the population is resident in southern Patagonia (link to Seasonality map).

 

Habitat

Mostly coastal, using gravely and stony sea shores, sandy beaches, estuaries, intertidal mudflats, saltmarshes and tidal creeks. Also recorded in wet grasslands along the coast of lagoons and rivers. In coastal areas they move with the tide cycle and concentrate in roosting sites in big numbers during high tide.

 

Habits and interactions with human activities

Low overlapping with human activities. After breeding season in big numbers in coastal areas close to estuaries and harbours.
