Observations sur l'avifaune marine des îles Matthew et Hunter (Parc naturel de la mer de Corail), 1973-2018

Abstract : Twelve ornithological missions to the Matthew and Hunter volcanic islands took place during the period 1973-2018. The data collected on the diversity, abundance and reproductive status of 14 seabird species are compiled. The seabirds nesting on Matthew Island were the grey noddy Anous albivitta, the brown noddy A. stolidus, the wedge-tailed shearwater Ardenna pacifica, the sooty tern Onychoprion fuscatus, the red- tailed tropicbird Phaethon rubricauda, the black-winged petrel Pterodroma nigripennis, the masked booby Sula dactylatra, the brown booby S. leucogaster and possibly the white tern Gygis alba. An undetermined storm petrel, perhaps the Polynesian storm petrel Nesofregetta fuliginosa may also breed on Matthew Island. Seabirds nesting on Hunter Island were the grey noddy, the black noddy Anous minutus, the brown noddy, the wedge-tailed shearwater, the lesser frigatebird Fregata ariel, the great frigatebird F. minor, the white tern, the red-tailed tropicbird, the Herald petrel P. heraldica, the black-winged petrel, the masked booby, the brown booby and the red-footed booby S. sula. Brown noddies bred exclusively during the austral summer, as did the wedge-tailes shearwater and the black-winged petrel, while the two frigatebirds and the Herald petrel seemed to prefer winter. The grey noddy, the sooty tern, the red-tailed tropicbird, the masked booby, the brown booby and the red-footed booby appeared to reproduce throughout the year. The threats to seabirds identified on these two islands were introduced grass Cenchrus echinatus, Polynesian rat Rattus exulans (on Hunter), disturbance due to human activities, trampling of burrows, military shooting practice, helicopter movements, as well as night lights on land and on board ships moored near the seabird colonies. We recommend an end to shooting practice and to the use of helicopters above both islands, as well as the eradication of the Polynesian rat on Hunter Island.
