This data set describes the population dynamics of Wilson's Storm Petrels (Oceanites oceanicus) at King George Island (Islas 25 de Mayo, Antarctica) over a forty year period (1978 - 2020). It includes all available data on Wilson's Storm Petrels from two colonies: around the Argentinian Base Carlini (62°14′S, 58°40′W; CA, formerly called Base Jubany) and the Henryk Arctowski Polish Antarctic Station (62°09′S, 58°27′W; HA). Data on adult abundance and estimated age categories (i.e., presence of foot spots; Quillfeldt et al. (2000, doi:10.1007/s003000000167) were collected at CA by using the same size mistnet every study year in the same location within the breeding colony. Adults were ringed with a metal leg ring, and their foot webs were checked for foot spots.
