Cape Robertson is an ice free point rising to over 250 m located on the western coast of Laurie Island, at the northern extremity of the Mackenzie Peninsula. The IBA qualifies on the basis of the concentration of seabirds present (in particular Chinstrap Penguin (Pygoscelis antarctica)) present, and extends from Cape Robertson to a coastal headland 1 km south of Cape Roca on the southern coastline of Laurie Island.
The nearest research station is Orcadas (ARG) which is located less than 5 km to the southeast of the IBA. Orcadas operates year-round with around 45 personnel present in summer and 14 in winter (COMNAP, Antarctic Facilities, accessed 01/09/2010).
Approximately 19 745 pairs of Chinstrap Penguin were breeding at Cape Robertson in 1994 (unpublished data N. Coria, compiled by E. Woehler pers. comm. 2004)), with a further 1300 pairs breeding along the coast between Cape Robertson and Cape Roca, and ~1900 pairs breeding at Cape Roca itself (Poncet & Poncet 1985).
Non-bird biodiversity: None known.
