Thirteen ornithological trips to the Matthew and Hunter volcanic islands took place during the period 1973-2018, whose data on the diversity, abundance and reproductive status of 14 seabird species were compiled. The seabirds nesting on Matthew Island were the black-winged petrel Pterodroma nigripennis, the wedge-tailed shearwater Ardenna pacifica, the red-tailed tropicbird Phaethon rubricauda, the masked booby Sula dactylatra, the brown booby S. leucogaster, the brown noddy A. stolidus, the grey noddy Anous albivitta, the sooty tern Onychoprion fuscatus, and possibly the white tern Gygis alba. An undetermined storm petrel may also breed on Matthew Island. Seabirds nesting on Hunter Island were the Herald petrel Pterodroma heraldica, the black-winged petrel, the wedge-tailed shearwater, the red-tailed tropicbird, the masked booby, the brown booby, the red-footed booby S. sula, the lesser frigatebird Fregata ariel, the great frigatebird F. minor, the black noddy Anous minutus, the brown noddy, the grey noddy, and the white tern. Brown noddies bred exclusively during the austral summer, as did the black-winged petrel and the wedge-tailed shearwater, while the Herald petrel and the two frigatebirds seemed to prefer winter. The main threats to seabirds identified on these two islands were introduced grass Cenchrus echinatus, Polynesian rat Rattus exulans (on Hunter Island), disturbance due to human activities, trampling of burrows, military shooting practice, helicopter movements, as well as night lights on board ships near the seabird colonies. We recommend an end to shooting practice and to the use of helicopters above both islands, a strict limitation of the number of visitors and the length of visits to the islands, as well as the eradication of the Polynesian rat on Hunter Island. ; Treize missions ornithologiques ponctuelles sur les îles volcaniques Matthew et Hunter ont été recensées durant la période 1973-2018, dont les données sur la diversité, l'abondance et le statut reproductif de 14 espèces d'oiseaux ...

Le pétrel est un petit oiseau de mer de couleur foncée qui, par gros temps, vole entre les vagues pour se protéger. Les vieux marins l'appellent «oiseau des tempêtes«, car il annonce le danger.

The Anchorage Islets, located along the eastern barrier of the southern part of the Chesterfield-Bampton atoll, are a major site for the reproduction of seabirds and green turtles in the western tropical Pacific, including two threatened species. The government of New Caledonia has designated as so-called integral reserves an "îlot du Nord-Est" and an "îlot du Mouillage no. 1". However, these two islets cannot be clearly identified from the sole official decree. Moreover, different names have been used in the previous literature. Here, the two islets are identified, the synonymies for all Anchorage islets are established, and a stabilization of the toponymy is proposed. ; Les îlots du Mouillage, situés le long de la barrière est de la partie sud de l'atoll des Chesterfield-Bampton sont un site important pour la reproduction des oiseaux marins et des tortues vertes du Pacifique tropical ouest, dont deux espèces menacées d'extinction. Le gouvernement de la Nouvelle-Calédonie a classé deux des îlots en réserves dites intégrales, un « îlot du Nord-Est » et un « îlot du Mouillage n° 1 » qui cependant ne peuvent être identifiés clairement à partir du seul document officiel. De plus, une disparité de noms sont utilisés dans la littérature. Ici, ces deux îlots sont identifiés, les synonymies pour l'ensemble des îlots du Mouillage sont établies et une stabilisation de la toponymie est proposée.

The islets of the coral atolls of the New Caledonian Coral Sea Natural Park are among the last places in the Tropics with large colonies of a remarkable diversity of seabirds. They are also nesting sites for the green turtle. The reason is that these islets are protected by their remote-ness and that seabirds and sea turtles are less affected by human disturbance than in sites clos-er to human activities. An essential objective of the Natural Park is the "preservation of heri-tage, rare, endangered and migratory species". A preliminary analysis of the Natural Park's management decrees taken in August 2018 reveals, however, that the government of New Cal-edonia intends to develop professional tourism activities there and that it plans to let cruise ships and yachts enter the nature reserves, possibly drop anchor, and disembark passengers. Ultimately, as is now well documented, tourism activities including those pretending to be "sustainable" and "respectful of the environment" will inevitably lead to a demographic decline of the species most susceptible to disturbance, increasing the risk of their local extinction. Many of these species, including seabirds, sea turtles, sea snakes and marine mammals qualify as heritage, rare, endangered and migratory species. Therefore, there is a contradiction between the stated objectives and the regulations that have been published. This leads to the hypothesis that conservation issues were not correctly evaluated during the elaboration of the texts. ; Les îlots des atolls coralliens du parc naturel de la mer de Corail comptent parmi les derniers endroits de la zone intertropicale abritant des colonies nombreuses d'une diversité remarquable d'oiseaux marins.
