Abstract:
Information is presented on the results of 16 bird censuses of the western inlet and saltmarsh of the Puerto Espora area (Tierra del Fuego) on the first narrows of the Straits of Magellan. This area was one of the most affected by the oil spilled from the VLCC Metula in august 1974. The censuses were carried out periodically between September 1976 and September 1979. A total of 36 species were recorded, of which one third is commonly found. Topics analyzed include: the presence of species by sectors within the study area; the general diversity for each census, its variation through time and cluster analysis.
