Kleptoparasitic feeding by migrating skuas in Malaga Bay, Spain
Arctic Skuas were the most numerous skua in Malaga Bay, accounting for 94% of observed chases, with ten species of victim. Adult Arctic Skuas were more successful than immatures. No difference was
Kleptoparasitism by brown skuas on albatrosses and giant-petrels in the Indian Ocean
TLDR
An attempted kleptoparasitism by a Brown Skua on a Light-mantled Albatross in the Kerguelen Archipelago, and four attempts by Brown Skuas on Yellow-nosed Albatosses adjacent to the primary breeding colony of the latter at Amsterdam Island are reported.
Kleptoparasitic interactions of Arctic Skuas Stercorarius parasiticus and Black Guillemots Cepphus grylle in northeastern Hudson Bay, Canada
Kleptoparasitic behaviour of Arctic Skuas was studied at a Black Guillemot colony in northeastern Hudson Bay, Canada. Skuas procured fish in 7-2% and 19-9% of attacks, and Black Guillemots lost fish
Population ecology of Arctic skuas Stercorarius parasiticus, on Foula
TLDR
Both Arctic skua chick growth and fledging success were depressed during the years of low sandeel Ammodytes marinus availability, and changes in behaviour may act as a buffer allowing Arctic skuas to withstand some degree of reduced prey availability.
Kleptoparasitism By Kermadec Petrels, Jaegers, And Skuas In The Eastern Tropical Pacific: Evidence Of Mimicry By Two Species Of Pterodroma
TLDR
The Kermadec Petrel is smaller or similar in size to its preferred hosts and is not as aggressive as large skuas, but its rate of success as a parasite is higher than expected, and this petrel's incidence of attack and frequent use of alternate feeding methods suggests that it is a less specialized parasite than are the skUas.
Frequency-dependent morph differences in kleptoparasitic chase rate in the polymorphic arctic skua Stercorarius parasiticus
TLDR
The relationship between colouration and kleptoparasitic efficiency (success rate and chase rate) was studied in the polymorphic arctic skua, Stercorarius parasiticus, at a Mediterranean migration site to support the apostatic selection hypothesis.
Predation and Kleptoparasitism by Migrating Parasitic Jaegers
TLDR
It was found that in addition to kleptoparasitism, jaegers also preyed upon invertebrates (Gammarus spp.), ducks, and shorebirds, andpredation of shorebirds was mainly performed by territorial Jaegers which restrained other jaeger from the main hunting area.
Ecology and behaviour of great skuas breeding on Foula (Shetland)
TLDR
Aspects of the ecology and behaviour of Great Skuas breeding on Foula were investigated by studying individually marked birds and predictions that arise from theories of territorial intrasions and copulation behaviour in birds were tested.
DOES KLEPTOPARASITISM BY GLAUCOUS-WINGED GULLS LIMIT THE REPRODUCTIVE SUCCESS OF TUFTED PUFFINS?
TLDR
Investigation of effects of kleptoparasitism by Glaucous-winged Gulls on a population of Tufted Puffins found they were unlikely to cause reproductive failures that characterize puffins at that site and merit further attention in explaining those failures.
The dynamics of gull-puffin interactions: implications for management
TLDR
Analysis of data collected over a 23 year period showed that the recruitment rate of puffins to the colony was significantly higher in the areas of the island where gull nest density was low, suggesting that, by reducing the density and spatial distribution of nesting gulls, the control programme successfully increased the attractiveness of the colony as a potential breeding site for puffins.

Studies on the breeding biology and population dynamics of the great skua (Catharacta skua Brünnich)
TLDR
Evidence is presented suggesting that the Great Skua first colonised the northern hemisphere around 1500 AD, and its status in seabird communities, and to find reasons for current population increases are found.
Interactive Behaviour of Puffins (Fratercula Arctica L.) and Skuas (Stercorari Us Parasiticus L.)
Puffins fly to their burrows with food (fish) in their beaks for the single chick they raise. Skuas chase puffins and induce them to drop their food. If the skuas do not catch the falling food before
Predation and Piracy by Gulls at a Ternery in Maine
TLDR
It will be shown that a substantial number of chicks are now lost to the large gulls and that fish-stealing is likely to be significant when the terns find fishing difficult.
Piracy by Black-headed Gulls on Lapwings
A description and a quantitative analysis are given of Black-headed Gull piracy on Lapwings, as observed in Sweden where such behaviour occurs mainly in autumn and early spring. It is concluded that
