An understanding of animal behaviour is important if conservation initiatives are to be
effective. However, quantifying the behaviour of wild animals presents significant …

Animal movement comes in a variety of 'types' including small foraging movements, larger
one-way dispersive movements, seasonally-predictable round-trip migratory movements …

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 …

Offspring sex ratios in wild bird populations, and the extent to which they vary from the
equality expected by random genotypic sex determination, have received much recent …

(Invited Article) Abstract Sexual size dimorphism (SSD) is widespread and variable among
animals. According to the differential equilibrium model, SSD in a given species is expected …

Sexual segregation occurs when members of a species separate such that the sexes live
apart, either singly or in single‐sex groups. It can be broadly categorised into two types …

Many established models of animal foraging assume that individuals are ecologically
equivalent. However, it is increasingly recognized that populations may comprise 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 …

Sexual segregation by micro–or macrohabitat is common in birds, and usually attributed to
size–mediated dominance and exclusion of females by larger males, trophic niche …

While personality differences in animals are defined as consistent behavioural variation
between individuals, the widely studied field of foraging specialisation in marine vertebrates …
