南乔治亚州在鸟岛对20,000只流浪信天翁进行了30年的振铃，仅产生了81次回收(即不包括对照)，相当平均地分布在成鸟和雏鸟环抱的鸟类之间，以及振铃后1-3年(70%的前雏鸟)和随后恢复的鸟类之间。1960-1974年期间(远离南乔治亚附近)的鸟类主要在澳大拉西亚(41%)，其次是南美洲(34%)；17%的鸟类是在岸上发现的，其余38%是在捕鱼时捕获的。从1975年到1988年，回收的鸟类主要在南美洲(65%)，然后是澳大拉西亚(25%)；28%的鸟类是在岸上发现的，其余63%(几乎相等的成鸟和幼鸟)是在捕鱼时捕获的，其中四分之三(%成鸟)是在为金枪鱼而设的长线上捕捞的。与捕鱼(特别是延绳钓)相关的恢复增加，以及鸟岛(和其他几个)繁殖种群的减少，可能不仅仅是巧合。
Ringing of 20,000 Wandering Albatrosses over 30 years at Bird Island, South Georgia has produced only 81 recoveries (i.e. excluding controls), fairly evenly distributed between birds ringed as adults and as nestlings and between birds recovered 1–3 years after ringing (70% ex‐nestlings) and subsequently. Recoveries (away from the vicinity of South Georgia) from 1960–1974 were mainly in Australasia (41%), followed by South America (34%); 17% of birds were found ashore, of the rest 38% were caught during fishing. From 1975–1988, recoveries were mainly in South America (65%), then Australasia (25%); 28% of birds were found ashore, of the rest 63% (almost equally adults and juveniles) were caught during fishing and three‐quarters (64% adults) of these on long‐lines set for tuna. The increase in recoveries associated with fishing (and with long‐lines in particular) and the decline of the Bird Island (and several other) breeding population is probably more than coincidence.
