Half Moon Island

Half Moon Island is a small Antarctic Island located in McFarlane Strait. With a total area of approximately 171 hectares, it is one of the smallest islands in the Antarctic archipelago. Despite its modest size, Half Moon Island is of significant scientific and ecological importance, attracting researchers and nature enthusiasts from around the world. Geologically, the island is a product of volcanic activity, with basaltic rocks dominating its landscape. The terrain is rugged and mountainous, with steep cliffs and rocky outcrops giving way to tranquil bays and coves. The island's unique geology has created a diverse range of habitats, supporting an astonishing array of flora and fauna. One of the most notable features of Half Moon Island is its incredible wildlife. The island supports a breeding colony of approximately 100 pairs of South Polar Skuas and has been designated an Important Bird Area by BirdLife International. Other birds that nest on the island include 2000 pairs of Chinstrap Penguins, 125 pairs of Antarctic Terns, and 40 pairs of Kelp Gulls. Wilson's and Black-Bellied Storm Petrels, Cape Petrels, Brown Skuas, Snowy Sheathbills and Imperial Shags are also live on the island. The island's shores are also home to a variety of seals, including the Weddell Seal and the Crabeater Seal, which can be spotted basking in the sun or playing in the waves. In addition, whales are often seen patrolling the coastline. Today, the island is used as a stop on Antarctic cruises, with peak visitation between November and March.
