Contributions to the natural history of the Correndera Pipit (Anthus correndera chilensis) Anthus correndera chilensis is one of the six subspecies of the Correndera Pipit. It is widely distributed in Chile andArgentina, but despite being common in its habitat, knowledge of essential aspects of its natural history is poor. Itsdistribution in Chile ranges from the region of Atacama to Isla Navarino in the Magallanes region, while in Argentina itis distributed from Laguna Seca, province of Mendoza to Tierra del Fuego along the Andes, and on a narrow strip alongthe Atlantic coast between Tierra del Fuego and the south of the Province of Río Negro. Based on information gener ated in 10 localities of Chile and Argentina, we present new information on distribution, biometry, vocalizations,breeding, and plumage/molting. Despite the large number of presence records available, there are areas of distribu tion in Argentina that require exploration. Because the boundaries with other subspecies, such as correndera andcatamarcae, are incompletely known, range overlaps are likely. Plumage molt presented a pattern similar to thatreported for other Anthus species, with a formative, alternate, and basic molting (alternate complex strategy) pat terns. In total we recorded a vocal repertoire of two different song types: territorial and perched; and three call types:alert, complaint, and request of nestlings. Out of these, the most frequent and complex was the territorial song.
