Claim: Lacepede Islands have been identified by BirdLife International as an Important Bird Area breeding colony of brown boobies and up to 20,000 roseate terns have been recorded there.
Evidence: The islands have been identified by BirdLife International as an Important Bird Area (IBA) because they support over 1% of the world populations of brown boobies and roseate terns. The breeding colony of brown boobies, of up to 18,000 breeding pairs, is possibly the largest in the world. Up to 20,000 roseate terns have been recorded there.
