Site description

Foyn Island is the second largest of the Possession Islands, which lie 17 km east of Cape Roget, at the southern extremity of Adare Peninsula, Borchgrevink Coast, northern Victoria Land. Foyn Island extends around 2 km across.

The IBA qualifies on the basis of the concentration of seabirds present (in particular Adélie Penguin (Pygoscelis adeliae)) and comprises the entire island.

The nearest permanent stations are Mario Zucchelli (ITA) and Jang Bogo (KOR), ~370 km to the south in Terra Nova Bay.

Key biodiversity

The Adélie Penguin colony at Foyn Island had a mean of 30 494 breeding pairs over 6 seasons sampled from 1981 – 2012 (Lyver et al. 2014). South Polar Skuas (Catharacta maccormicki) are also present on the island, with 397 breeding pairs recorded in the 1980s (Ainley et al. 1986), although because this count was made from an aerial survey it has not be used for the purpose of assessing the IBA. No recent information is available on the skua colony, and information on other birds breeding in the area is not available.

Non-bird biodiversity: None known.
