Catharacta

Variations in size and growth of Great Skua Catharacta skua chicks in relation to adult age, hatching date, egg volume, brood size and hatching sequence.

Diets and feeding ecology of great skuas Catharacta skua during the breeding season in Shetland.

One study found that about 38% of great skua (Catharacta skua) pellets were produced within six hours of a meal (Votier et al., 2001), suggesting that gulls could produce pellets or food remains at the first loafing site used after feeding.

The terrain surrounding colonies at Livingston Island (Cape Shirreff) is gently sloping, open, and accessible to pups but has no tussock grass for cover; pups roam inland, but may spend less time there than pups at South Georgia because they would be more exposed to harassment by giant petrels (Macronectes giganteus), skuas (Catharacta spp.), and subadult male fur seals.
