![]() ![]() ![]() Winter energyscapes were modelled with Niche Mapperâ„¢, a mechanistic tool which takes into account local climate and bird ecophysiology. Across six winters, we tracked the migration of 94 little auks ( Alle alle), a key sentinel Arctic species, between their East Greenland breeding site and wintering areas off Newfoundland. We compared the winter location of seabirds with their modelled energy requirements and prey fields throughout the North Atlantic. Here, we analysed the ecological drivers of seabird migration within the framework of the energyscape concept, which we defined as the variations in the energy requirements of an organism across geographical space as a function of environmental conditions. Most current analyses require long-term monitoring of populations on the move, and shorter-term approaches are needed. There is an urgent need for a better understanding of animal migratory ecology under the influence of climate change. ![]()
