An immature male Siberian Blue Robin Larvivora cyane was recorded on West Island, Ashmore Reef, off northwestern Australia, on 23-25 April 2012. This is the first record of this species anywhere in Australia or its territories. © 2016, Bird Observers Club of Australia (BOCA). All rights reserved.

A Lesser Coucal Centropus bengalensis was discovered on West Island, Ashmore Reef, the External Australian Territory off the northern coast of Western Australia, during an expedition there in October 2005. This was accepted by the Birds Australia Rarities Committee, Case no. 484, as the first record of the species for Australia.

Understanding spatial and temporal variability in the distribution of species is fundamental to the conservation of marine and terrestrial ecosystems. To support strategic decision making aimed at sustainable management of the oceans, such as the establishment of protected areas for marine wildlife, we identified areas predicted to support multispecies seabird aggregations in the Timor Sea. We developed species distribution models for 21 seabird species based on at-sea survey observations from 2000-2013 and oceanographic variables (e.g., bathymetry). We applied 4 statistical modeling techniques and combined the results into an ensemble model with robust performance. The ensemble model predicted the probability of seabird occurrence in areas where few or no surveys had been conducted and demonstrated 3 areas of high seabird richness that varied little between seasons. These were located within 150 km of Adele Island, Ashmore Reef, and the Lacepede Islands, 3 of the largest aggregations of breeding seabirds in Australia. Although these breeding islands were foci for high species richness, model performance was greatest for 3 nonbreeding migratory species that would have been overlooked had regional monitoring been restricted to islands. Our results indicate many seabird hotspots in the Timor Sea occur outside existing reserves (e.g., Ashmore Reef Marine Reserve), where shipping, fisheries, and offshore development likely pose a threat to resident and migratory populations. Our results highlight the need to expand marine spatial planning efforts to ensure biodiversity assets are appropriately represented in marine reserves. Correspondingly, our results support the designation of at least 4 new important bird areas, for example, surrounding Adele Island and Ashmore Reef. © 2014 Society for Conservation Biology.

Island Monarchs Monarcha cinerascens were observed at Ashmore Reef during the months of October and/or November in 2004, 2007, 2008, 2009 and 2010. In 2010 up to four were present together, and we consider that more than six individuals visited the Reef that year. Only single birds were observed on previous occasions. Thus the total number of Island Monarchs that has been detected on the Reef is at least eight and probably greater than ten. Reports of the 2004, 2007, 2008 and 2009 observations were assessed and accepted by the Birds Australia Rarities Committee (Case nos 467, 544, 581 and 701, respectively), with the 2004 observation being the first record for Australian territory. This paper documents all known occurrences on Ashmore Reef. We postulate that these occurrences are examples of dispersal of birds seeking suitable habitat beyond their usual range in the islands of the Indonesian archipelago just to the north.

Jouanin's Petrel Bulweria fallax mainly occurs in the western Indian Ocean. Prior to our study there were only two records from east of 82° E. We show that small numbers of Jouanin's Petrels are regular visitors to the eastern Indian Ocean, occurring to 15° N 90° E in the Bay of Bengal and 15° S 123° E off northern Australia. Although seasonal coverage is limited, they have been recorded east of 80° E from April-July and October- December, but not in February-March. Most sightings are from oceanic waters at least 20 km offshore where depths exceed 500 m. © NISC (Pty) Ltd.

A White-throated Nightjar Eurostopodus mystacalis was photographed flying low above the sea in the Gulf of Carpentaria, Queensland, at - 1600 h on 25 August 2010. Sightings of Nightjars behaving similarly in the same area in the days before obtaining the conclusive photographs suggest that they were on southerly migration, returning from their wintering sojourn in New Guinea to their breeding grounds in Australia. Other relevant sightings are given, and the significance of this behaviour is discussed.

This note records the occurrence of a Siberian Peregrine Falcon Falcoperegrinus calidus on Christmas Island, Indian Ocean, in January 2010: apparently the second record for Australian territory of this migratory, Arctic subspecies. This is also the fifth record of a vagrant Peregrine Falcon on Christmas Island, although the others could not be identified to subspecies.
