Site location and context
Trinity Island is part of the Palmer Archipelago and lies in Orléans Strait, ~15 km from the Davis Coast of the Antarctic Peninsula. The IBA qualifies on the basis of the Imperial Shag (
Phalacrocorax [
atriceps]
bransfieldensis) colony present and comprises a rocky headland rising to ~250 m at the southwestern extremity of Trinity Island.
The nearest permanent station is Primavera (ARG), located 30 km to the south.
Around 195 pairs of Imperial Shag were recorded breeding in three groups along the rocky headland amongst Chinstrap Penguins (
Pygoscelis antarctica) on 28 January 1986 (unpublished data S. Poncet pers. comm. 2005). The Chinstrap Penguin colony was recorded as 1600 breeding pairs (Poncet & Poncet 1987).
