Abstract

CARCAMO, Jaime  and  CORTES, Humberto. Waterbirds diversity of laguna Barrosa, Tierra del Fuego, Chile. Anales Instituto Patagonia (Chile) [online]. 2021, vol.49, 9.  Epub Sep 30, 2021. ISSN 0718-686X.  http://dx.doi.org/10.22352/aip202149009.

Laguna Barrosa is one of the four large lagoons that are in the northwest of Tierra del Fuego, 20 kilometers from the city of Porvenir. This lagoon has not been mentioned in the literature and is not known as an important site for the conservation of birds in the Magallanes. In this work, the seasonality of waterfowl is described through 10 visits made from April 2015 to January 2016. 24 species of waterfowl were recorded, 9 of which are in some category of conservation, within which the ruddy-headed goose (Chloephaga rubidiceps) and Magellanic plover (Pluvianellus socialis) stand out, both categorized as Endangered (EN). The upland goose (Chloephaga picta), crested duck (Lophonetta specularioides) and coscoroba swan (Coscoroba coscoroba) dominated the assemblage in all the seasons of the year, both in terms of abundance and in terms of frequency of occurrence. The abundance of the coscoroba swan stands out, which represents between 4 and 10% of the world population and the importance of the lagoon as a wintering site for the Chilean flamingo (Phoenicopterus chiiensis). The analysis of similarity showed that the structure of the assemblage of birds in the wetland shows a temporal trend of a seasonal nature. In general, we highlight Laguna Barrosa as an important resting and feeding site for the waterbirds of Tierra del Fuego and the Magallanes region.
