8 thoughts on “New Caledonian Storm-petrel (Fregetta lineata)”
We have received the following contribution from Nicholas Carlile via email:
“I am writing to support of the newly recognised New Caledonian Storm-petrel as data deficient species in the Pacific as part of the reassessed for the 2023 Red List update.
The ground work by Bretagnolle and others is quite extensive and the strength of their species specific data is convincing. Its potential location certainly compelling. The species nomination as data deficient will assist in gaining further support to not only pinpoint colony location(s), but also draw attention to urgently needed research and monitoring so that the species can be safeguarded against potential predator impacts into the future. It is interesting to note that the island most likely for their presence had rats detected, then removed in the first decade of this century.”
There is a mistake in the paper from Bretagnolle regarding Lepredour islet that is considered by the authors as a possible breeding site, saying ” The most suitable location would be Leprédour Islet where introduced mammals were recently eradicated. ”
Introduced mammals have not been eradicated at all on Lepredour islet that unfortunately still houses invasive populations of Rusa deers Rusa timorensis, Rabbits Oryctolagus cuniculus, Ship rats Rattus rattus, Polynesian rats Rattus exulans, as well as two major invasive ant “biting” species Solenopsis geminata, Anoplolepis gracilipes and Wasmannia auropunctata (Ref : Vidal E., Saint-Germes N, Rigault F., Jourdan H. 2016. Travaux de suivi de la qualité des milieux de la réserve Naturelle de l’îlot Leprédour. IRD/Province Sud, Unpublished report, 51p.
Therefore Lepredour islet habitats are still very degraded and some playback sessions recently conducted by the NGO Bird Conservation New Caledonia have been unsuccessful
Anyway, I support the classification of the New Caledonian Storm-petrel as DD data deficient species for the 2023 Red List update until we have more information and knowledge about the species, its distribution and the threats it faces.
Supportive of DD. An argument could be made for stable or increasing given increasing rate at which the species is being detected off SE Qld but some of this increase reflects more targeted surveys over the eastern Australian seamounts chain, and other changes could conceivably reflect range shift rather than population increase. Publication of all Australian records (of which there are relatively large numbers given routine citizen science-led surveys to marine waters off SE Qld and NE NSW cf New Caledonian waters) would be valuable. There is a recent record off eastern Victoria, Australia (well photographed but not yet vetted by the Australian Rarities Committee) that suggests southern bound of mapped range may extend further south than is currently indicated.
Many thanks to everyone who has contributed to this discussion. We greatly appreciate the time and effort invested in commenting. The window for consultation is now closed and we are unable to accept any more comments until 26 June 2023. We will now analyse and interpret the new information, and we will post a preliminary decision on this species’ Red List status on this page on 26 June 2023, when discussions will re-open.
Based on available information, our preliminary proposal for the 2023 Red List would be to adopt the proposed classifications outlined in the initial forum discussion. It is noted that introduced mammals remain present on Leprédour Islet, which has been identified as a possible breeding site, and this information has been added to the species factsheet.
There is now a period for further comments until the final deadline on 2 July 2023, after which the recommended categorisations will be put forward to IUCN.
The final 2023 Red List categories will be published on the BirdLife and IUCN websites in December 2023, following further checking of information relevant to the assessments by both BirdLife and IUCN.

Recommended categorisation to be put forward to IUCN
The final categorisation for this species has not changed. New Caledonian Storm-petrel is recommended to be listed as Data Deficient.
