The nearest permanent station is Davis (AUS), ~6 km to the northeast on Broad Peninsula, Vestfold Hills.
Key biodiversity
Approximately 21 358 pairs of Adélie Penguin were estimated as breeding at the unnamed island using satellite imagery from February 2012 (unpublished data H. Lynch & M. LaRue pers. comm. 2014: CI not available). In 1981/82 the colony size was estimated with 10 522 breeding pairs (Whitehead & Johnstone 1990). The breeding colony is situated on the northern part of the island on both the east and west coast. Lynch & LaRue (2014) grouped records of Adélie Penguins present on the unnamed island in Donskiye Islands IBA with Warriner Island IBA, Lugg, Magnetic and Turner Islands IBA, and Gardner Island IBA and referred to these as ‘Vestfold South'.
No other birds are known to breed in the area.
Non-bird biodiversity: None known.
