 The islets are part of the Franklin Sound Islands Important Bird Area, identified as such by BirdLife International because it holds over 1% of the world populations of six bird species.Recorded breeding seabird and wader species are little penguin, white-faced storm-petrel, sooty oystercatcher, pied oystercatcher and Caspian tern.Rats are present, with evidence that they prey on the storm-petrels.
