Abstract

We present standardized, quantitative information on the avifauna of the Drake Passage obtained during six crossings between Patagonia and the South Shetland Islands during the summer­–autumn period, 1998–2020. We compare inter-annual and seasonal patterns of species occurrence, adding to previous, published surveys, and we discuss species association with the different zones and water masses of the region.
