 Also gazetted as rare, the Australasian subspecies of the lesser noddy, "Anous tenuirostris melanops", breeds only on Wooded Island, Morley Island and Pelsaert Island.Only two species of land mammal are indigenous to the Houtman Abrolhos, the tammar wallaby ("Macropus eugenii") and the bush rat ("Rattus fuscipes").Both are native only to West and East Wallabi Islands, although "R. fuscipes" has not been collected on East Wallabi Island since August 1967, and is probably extinct there.
