Earle Island is ice-free and of low elevation, is around 0.5 km across, and is the most southerly of the Danger Islands. The IBA qualifies on the basis of the concentration of seabirds present (in particular Pygoscelid penguins) and comprises all of Earle Island. The nearest permanent scientific station is Petrel (ARG, a summer-only facility for up to ~55 people (COMNAP, Antarctic Facilities, accessed 06/08/2010) located ~70 km to the east on Dundee Island.
