Gibbney Island

Gibbney Island is a small island on the west side of Holme Bay, off Mac. [Robertson Land], Antarctica. It was mapped by Norwegian cartographers from air photos taken by the Lars Christensen Expedition, 1936–37, and named "Bryggeholmen". It was renamed by the Antarctic Names [Committee of Australia] for L.F. Gibbney, officer in charge at Heard Island station in 1952.

Important Bird Area

A 17 ha site, comprising the whole island and adjacent islets, has been designated an Important Bird Area by BirdLife International because it supports a breeding colony of about 12,000 Adélie penguins, mostly on the western side of the island, estimated from 2011 satellite imagery.
