Diet dichotomy between two migrant seabirds breeding near a high Arctic polynya [PDF]
High Arctic polynyas are predictable areas of open water, which offer long-distance migrant seabirds a reliable source of food during a period when they have to replenish and accumulate energy for reproduction.

Pair bonds during the annual cycle of a long-distance migrant, the Arctic Tern (Sterna paradisaea)
Background The extent to which pairs remain together during the annual cycle is a key question in the behavioural ecology of migratory birds. While a few species migrate and winter as family units, for most the extent to which breeding partners associate

Adult survival of Arctic terns in the Canadian High Arctic
Arctic tern (Sterna paradisaea) populations are thought to be in decline across much of their range. For long-lived seabirds, determining adult survival rates is key to understanding current population trends and predicting trajectories.

Variation in Population Synchrony in a Multi-Species Seabird Community: Response to Changes in Predator Abundance. [PDF]
Ecologically similar sympatric species, subject to typical environmental conditions, may be expected to exhibit synchronous temporal fluctuations in demographic parameters, while populations of dissimilar species might be expected to show less synchrony.

Reactions of ground-nesting marine birds to human disturbance in the Canadian Arctic
I studied the reactions of five ground-nesting marine bird species (Arctic tern (Sterna paradisaea), Sabine’s gull (Xema sabini), common eider (Somateria mollissima), long-tailed duck (Clangula hyemalis), and Ross’ gull (Rhodostethia rosea)) breeding in ...

Diversity and abundance of water birds in a subarctic lake during three decades
The numbers of divers, ducks, gulls, terns and waders in the 15 km2 oligotrophic lake Takvatn, North Norway were estimated six times during 1983-2012. Systematic mapping surveys were done by boat within the first week after ice-break in June.

Postbreeding dispersal and staging of Common and Arctic Terns throughout the western North Atlantic
In the western North Atlantic, Common (Sterna hirundo) and Arctic (S. paradisaea) Terns are sympatric at breeding colonies but show divergent migration strategies to coastal areas of South America and pelagic regions of the Antarctic, respectively ...
