TL;DR: The tracking of 11 Arctic terns fitted with miniature (1.4-g) geolocators revealed that these birds do indeed travel huge distances, and identified a previously unknown oceanic stopover area in the North Atlantic used by birds from at least two breeding populations.

TL;DR: In this article, the authors found that synchronous fluctuations of two congeneric seabird species across the entire Arctic and sub-Arctic regions were associated with changes in sea surface temperatures (SST) that were linked to two climate shifts, in 1977 and again in 1989.

TL;DR: The pattern of population expansion and colonization of new breeding grounds, in relation to breeding habitat quality, is reconstructed to investigate whether a buffer effect is also operating during the breeding season, and godwits appear to be expanding into poorer quality breeding habitat as well as poorer quality winter habitat.

TL;DR: It is concluded that although wintering area had a significant effect on both concentrations and patterns of POPs, its influence was small in compar- ison to differences in exposure to these pollutants at breeding colonies, but that accumulation of Pops during the winter may be important for specific populations of seabirds.

TL;DR: These ocean-wide migration patterns can ultimately be linked with breeding performance: colony productivity is negatively associated with wintering latitude, population size, and migration distance, which demonstrates the cost of competition and migration on future breeding and the link between non-breeding and breeding periods.
