格陵兰藤壶鹅Branta leucopsis在其主要的冬季出没，岛，苏格兰，的人口结构进行了研究，使用标记的个人在三个地点在他们的繁殖地在东格陵兰岛和岛上的越冬地。个别鹅在艾莱岛的分布被认为是非随机的。鸟类一般忠实于岛上有限的网站，无论是在冬季和连续的冬季之间。艾雷岛上的这些地点拥有格陵兰三个捕捞地点不同比例的个体。在格陵兰岛被抓到一起的鸟类在冬天的联系比如果它们的分布是随机的话所预期的要多。
The population structure of the Greenland Barnacle Goose Branta leucopsis at its main winter haunt, the island of Islay, Scotland, was studied using marked individuals caught at three sites on their breeding grounds in east Greenland and on the wintering grounds on Islay. The distribution of individual geese on Islay was found to be non-random. Birds were generally faithful to restricted groups of sites on the island, both within a winter and between consecutive winters. These groups of sites on Islay held different proportions of the individuals from the three catch sites in Greenland. Birds caught together in Greenland were associating in winter more than would be expected if their distribution were random.
