Rallier du Baty Peninsula

It is named for Raymond Rallier du Baty, a French sailor who charted the archipelago in the early 20th century.

The western half of the peninsula has been identified by BirdLife International as a 270 km2 Important Bird Area (IBA) because of its value as a breeding site for seabirds, with at least 31 species nesting there.

The site is bordered on the north by the Cook Glacier and, to the south and east, by the Arête Jérémine and the main mountain ridge of the peninsula.

[1] The western half of the Péninsule Rallier du Baty has the endemic but rare Lyallia Cushion.

Colonization of the site by mammalian species such as rats has gone up in recent years, since the glaciers that acted as barriers have been shrinking.
