The bay, with part of the south-western slopes of Mont Ross, has been identified as a 20 km2 Important Bird Area (IBA) by BirdLife International because of its breeding seabirds. Of the penguins, there are some 21,500 pairs of kings, 500 pairs of gentoos, 6000 pairs of macaronis and 4000 pairs of eastern rockhoppers. Other birds nesting in the IBA include a few pairs of wandering albatrosses, Antarctic and slender-billed prions, white-chinned, northern giant and common diving petrels, Kerguelen shags, Kerguelen terns, black-faced sheathbills and Eaton's pintails. Antarctic fur seals and southern elephant seals also breed on the shores of the bay.
