福克兰贼鸥是一种鲜为人知的海鸟。在2004年至2009年的短短5年间，对该分类群已知最大种群的人口统计研究显示，该种群数量急剧下降（47%）。这种下降似乎与近年来长期的低繁殖成功率有关，并与几乎零招募的情况相一致。到目前为止，这种下降的最终原因尚不清楚，但人们对合理的解释进行了研究和讨论。报告的人口趋势应该引起一些关注，需要进行更多的研究和监测。
The Falkland skua Stercorarius antarctica antarctica is a poorly known seabird. Demographic studies at the largest known colony of this taxon revealed a sharp population decline (47%) in just 5 years, between 2004 and 2009. The decline seems to be linked with a chronic low breeding success in the recent years and is consistent with a situation of virtually zero recruitment. The ultimate causes of the decline are, as of yet, unknown, but plausible explanations are examined and discussed. The reported population trends should be the cause of some concern, and more research and monitoring are desired.
