Mar de Ansenuza (often called Laguna Mar Chiquita) sits at the heart of the Ansenuza wetland complex and the Ansenuza National Park & Reserve in the northeast of the province of Córdoba. Mar Chiquita hosts three species (Chilean (Phoenicopterus chilensis) all year-round, Andean (Phoenicoparrus andinus) and James’s flamingos (Phoenicoparrus jamesi) as seasonal visitors). In many austral summers, Laguna Mar Chiquita is described as one of the most important non-breeding sites for Wilson’s Phalarope, with ≥400,000 recorded simultaneously in some years: the kind of spectacle that makes even seasoned birders go quiet. Why You Should Visit Mar Chiquita / AnsenuzaA genuinely major wetland: the Mar Chiquita–Río Dulce system is internationally recognised (Ramsar) and now has national-level protection as Ansenuza National Park. Flamingos on a huge scale: three South American species can be seen here, and Chilean Flamingos can exceed 300,000 individuals.
