Technological advances in recent years have seen an explosion of tracking and stable
isotope studies of seabirds, often involving repeated measures from the same individuals …

Summary 1 We studied chick diet in a known‐age, sexed population of a long‐lived seabird,
the Brünnich's guillemot (Uria lomvia), over 15 years (N= 136; 1993–2007) and attached …

Penguins, among the most delightful creatures in the world, are also among the most
vulnerable. The fragile status of most penguin populations today mirrors the troubled …

Ecological theory predicts that animals with similar foraging strategies should not be able to
co‐exist without segregating either in space, time or diet. In communities, intra‐specific …

Prehistoric faunal extinctions dramatically reshaped biological assemblages around the
world. However, the timing of such biotic shifts is often obscured by the fragmentary nature …

Chinstrap, Pygoscelis antarctica, and gentoo, P. papua, penguins are sympatric species that
inhabit the Antarctic Peninsula. To evaluate differences in the foraging habitat of these two …

Marine animals forage in areas that aggregate prey to maximize their energy intake.
However, these foraging 'hot spots' experience environmental variability, which can …

Marine predators adapt their hunting techniques to locate and capture prey in response to
their surrounding environment. However, little is known about how certain strategies …

Context. Diet variability is a significant driver of seabird decline; however, data on seabird
diet composition and trends have been affected by changes in precision and resolution …

Penguins require vision that is adequate for both subaerial and submarine environments
under a wide range of illumination. Here we provide a structured overview of what is known …
