Up for grabs: prey herding by penguins facilitates shallow foraging by volant seabirds [PDF]
Royal Society Open Science, 2019 Visual and olfactory signals are commonly used by seabirds to locate prey in the horizontal domain, but foraging success depends on prey depth and the seabird's ability to access it.

Mercury isotopes of key tissues document mercury metabolic processes in seabirds.
Chemosphere, 2020 Seabirds accumulate significant amounts of mercury (Hg) due to their long-life span together with their medium to high trophic position in marine food webs. Hg speciation and Hg isotopic analyses of total Hg in different tissues (pectoral muscles, liver,

Impacts of fisheries on seabird communities
Scientia Marina, 2003 Long-line by-catch of albatrosses and petrels may soon lead to species extinctions. Set-net bycatch has caused major reductions in certain seabird populations. Some fisheries may decrease numbers of seabirds by reducing abundance of prey-fish.

Identification of an assembly site for migratory and tropical seabirds in the South Atlantic Ocean
Global Ecology and Conservation, 2015 Seabirds are good indicators of wider biodiversity and where they assemble in large numbers signifies sites important to many marine faunal species. Few such large assemblage sites have been identified and none in pelagic waters has been identified in ...

Scientific Reports, 2017 Seabirds are known to concentrate on prey patches or at predators aggregations standing for potential feeding opportunities. They may search for prey using olfaction or by detecting visually feeding con-specifics and sub-surface predators, or even boats.

Mediterranean seabird conservation: what can we do?
Scientia Marina, 2003 Human activities in the Mediterranean determine, to a large extent, the availability of food and breeding sites for seabirds, the two most important ecological requirements for breeding seabirds.
