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 …

Seabirds are the most endangered avian taxa on Earth, with over a third of species globally
threatened. To help slow their decline, conservation physiology seeks to determine how …

Marine heatwaves (MHWs) are periods of anomalously warm water associated with
changes in ocean structure, based on the horizontal advection of water masses and …

More than half of the world's 18 penguin species are declining. We, the Steering Committee
of the International Union for Conservation of Nature Species Survival Commission Penguin …

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

While differences in foraging and reproductive success are well studied between seabird
colonies, they are less understood at a smaller subcolony scale. Working with little penguins …

Reproductive performance typically improves with age, reaching a plateau at middle age
and subsequently declining in older age classes (senescing individuals). Three potential …

Animal vocalisations play a role in individual recognition and mate choice. In nesting
penguins, acoustic variation in vocalisations originates from distinctiveness in the …

Detecting changes in marine food webs is challenging, but top predators can provide
information on lower trophic levels. However, many commonly measured predator …

Marine top and meso predators like seabirds are limited by the need to breed on land but
forage on limited or patchily distributed resources at sea. Constraints imposed by such …
