Determining the diet of wide-ranging, pelagic seabirds is challenging. In this study, we investigated buccal swabbing and DNA metabarcoding to describe the diet of Manx shearwaters (Puffinus puffinus....

Movement is a key part of life for many species. In solitary animals, the energetic costs of movement can be mitigated through energetically efficient strategies that produce faster, straighter moveme...

Background In wildlife studies, animal behavior serves as a key indicator of the impact of environmental changes and anthropogenic disturbances. However, wild animals are elusive and traditional GPS s...

Changes in migratory performance with age are typically assumed to reflect within-individual learning processes. Here, we show that changes the navigational efficiency in a long-lived seabird instead....

Analysis of combined deployments of GPS loggers with cameras or temperature–depth recorders reveals that despite experiencing intraspecific competition for food, northern gannets engage in dynamic, c...
