parasiticus "salteador parasito", muy raro de observar en Villa, aunque frecuente en otras areas de la costa peruana como Paracas y Mejia (Pulido 1987).
Hence, gulls and other intermediate vector hosts, such as the south polar skua (Stercorarius
maccormicki), might represent natural reservoirs that play a role in the introduction and maintenance of AIVs into Antarctica.
The most common birds of prey in the area are Rough-legged Buzzards (Buteo lagopus), Peregrine Falcons (Falco peregrinus), and Long-tailed and Arctic Skuas (Stercorarius
longicaudus and S.
On the YKD potential predators include Arctic Fox (Vulpes lagopus), and occasionally Red Fox (Vulpes vulpes), Mink (Mustek vison), jaegers (Stercorarius
spp.), and Glaucous Gulls (Laras hyperboreus).
. All of these were synonymized with A.
They are even said to dominate gulls (Laridae), skuas (Stercorarius
species), and fulmars (Fulmarus species) that may be competing with them.
He found a dor beetle (geotrupes stercorarius
) which had never been seen on the site.
Great skuas (Stercorarius
skua) are excellent at scrambling for the windfall, and the researchers suggest that abundant discards contributed to a jump in European skua populations during the past century.

To make it simpler, some details are not included: Some cephalopods eat small fish and are thus tertiary consumers, seals and birds export some of their production from the marine environment, and the great skua (Stercorarius
skua) migrates from pole to pole, leaving the southern hemisphere to breed.
(1955 [C]) and Andersson and Gotmark (1980 [C]) reported that jaegers (Stercorarius
spp.) feeding on abundant lemmings were territorial, but jaegers feeding on fish via Kleptoparasitism were not.
