Fine-scale spatial segregation in a pelagic seabird driven by differential use of tidewater glacier fronts
In colonially breeding marine predators, individual movements and colonial segregation are influenced by seascape characteristics. Tidewater glacier fronts are important features of the Arctic seascape and are often described as foraging hotspots. Albeit their documented importance for wildlife, lit...

In colonially breeding marine predators, individual movements and colonial segregation are influenced by seascape characteristics.
