Data from: Taking a trip to the shelf: behavioural decisions are mediated by the proximity to foraging habitats in the black-legged kittiwake
1. For marine top predators like seabirds, the oceans represent a multitude of habitats regarding oceanographic conditions and food availability. Worldwide, these habitats are undergoing alterations due to changes in climate and increased anthropogenic impact. This is causing a growing concern on ho...

1. For marine top predators like seabirds, the oceans represent a multitude of habitats regarding oceanographic conditions and food availability.

Understanding how seabird populations respond to fluctuating environmental conditions and to what extent behavioural flexibility can buffer variations in food availability, can help predict how seabirds may cope with changes in the marine environment. Such knowledge is important to implement proper long-term conservation measures intended to protect marine predators. 3.
