Brash Island

Brash Island is an isolated island lying northwest of Darwin Island, off the southeast end of Joinville Island. It was surveyed by the Falkland Islands Dependencies Survey in 1953, and so named by the UK Antarctic Place-Names Committee because the island lies in an area where there is a frequent occurrence of "brash ice".

Important Bird Area

The island has been identified as a 63 ha Important Bird Area by BirdLife International because it supports about 166,000 breeding pairs of pygoscelid penguins – probably mainly either Adélie or chinstrap penguins – based on a 2014 estimate from satellite imagery.
