Notes on the Breeding Population of the Polynesian Storm Petrel Nesofregetta fuliginosa on Motu Motiro Hiva (Salas y Gómez Island), Eastern South Pacific
AI summary Read the abstract
This study provided rare information on the reproductive biology and plastic ingestion of the endangered Polynesian Storm Petrel on Motu Motiro Hiva (Salas y Gómez Island) across seven visits between 2012 and 2024, finding breeding activity from August to November and nesting cavities in rocky areas. A 100% incidence of plastic ingestion was found in the 15 stomachs collected, indicating an urgent need to reduce marine debris entering the ocean near this remote active breeding colony.
The Polynesian Storm Petrel is an endangered seabird found in the tropical Pacific Ocean. Despite its critical conservation status, little is known about its population, its breeding biology, and the threats facing it. We provide information about its reproductive status, nesting areas, and plastic ingestion on the remote island of Motu Motiro Hiva. In seven visits between 2012 and 2024, we found breeding activity to occur from August to November, with nesting cavities located primarily on the rocky areas of the east and southeast sectors of the island. We found an extremely high incidence of plastic ingestion in the 15 stomachs collected (100%). Our study provides relevant information on the reproductive biology of this species in an active colony and shows an abundance of marine debris at the site, indicating an urgent need to stop the entry of this debris into the ocean.

Marine debris ingestion by adults and fledglings of Swinhoe's storm petrels in the Republic of Korea
AI summary Read the abstract
Researchers analyzed stomach contents of stranded Swinhoe's storm petrel carcasses from a Korean breeding colony and found that both adults and fledglings ingested predominantly microplastics, with juveniles consuming more plastic by weight than adults and the two age groups ingesting different particle shapes, suggesting separate foraging behaviors.
Barau's petrel, Pterodroma baraui, as a bioindicator of plastic pollution in the South-West Indian Ocean: A multifaceted approach
AI summary Read the abstract
This study evaluated Barau's petrel as a bioindicator of plastic pollution in the South-West Indian Ocean using necropsies, GPS tracking, manta trawling, and dispersal modeling, finding that 71% of analyzed birds had ingested plastic. GPS tracking showed adults consistently foraged in high-plastic-concentration areas, with the highest ingestion risk in the northwest of Reunion Island and at latitude 30°S, confirming the species as a reliable regional bioindicator.
Plastic ingestion by seabirds in New Caledonia, South Pacific
AI summary Read the abstract
Researchers examined stomach contents of 90 seabirds from 12 species in New Caledonia and found plastic debris in 14.4% of individuals, with the highest rates in procellariids (petrels and shearwaters), providing the first plastic ingestion baseline for this Pacific island region.
Prevalência e tipos de plásticos em Albatrozes e Petréis (aves: procellariiformes)
AI summary Read the abstract
Researchers quantified and classified plastic debris in Procellariiformes seabirds — albatrosses and petrels — found on Brazilian beaches, finding plastic ingestion in multiple species. These ocean-going birds are among the most vulnerable to plastic pollution because they feed from the ocean surface where plastics concentrate.
