A goal of seabird ecology is to relate the physiology, population dynamics, distribution and
behaviour of seabirds with their biotic and abiotic environments. One of the most challenging …

It is generally assumed that the extreme life history traits of pelagic seabirds, such as low
fecundity or slow growth of chicks, result from the difficulties obtaining energy at sea from …

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 …

Sexual differences in the foraging behaviour of parents have been observed in a number of
sexually sizedimorphic birds, particularly seabirds, and the usual inference has been that …

Evolution has produced a vast array of morphological and physiological adaptations in
seabirds that enable them to exploit the ocean's food resources in myriad ways. As …

Current guidelines for instrumenting birds state that external devices should not exceed 3–
5% of the birds' body mass; however, the energetic consequences of carrying any given …

254—PErSPEctivES in ornithology— Auk, vol. 125 movements in seabirds (eg, Anderson
and Ricklefs 1 87). This technology has severe limitations in location precision and range …

Breeding seabirds are extreme central-place foragers, commuting long distances between
colonies and feeding areas. Central-place foraging theory predicts that prey items close to …

We examined how seabirds might be used to study marine environmental variables, which
necessitates knowing location and the value of the variable to be studied. Five systems can …

We review the foraging ecology of seabirds at scales of 100s of m to 10s of km. We examine
processes responsible for the distribution and availability of seabird prey, and how …
