Tahiti Petrel

The Tahiti petrel (Pseudobulweria rostrata) is a medium-sized, dark brown and white seabird found across the Pacific Ocean. The species comprises two subspecies: P. r. rostrata which breeds in the west-central Pacific Ocean, and P. r. trouessarti which breeds in the tropical and subtropical Pacific Ocean. The Tahiti petrel belongs to the Procellariidae family and is the most studied member of the Pseudobulweria genus which comprises three critically endangered species. Similarly, the Tahiti petrel is considered near threatened by the 2018 IUCN Red List of Threatened Species. Threats include introduced rats, feral cats, pigs, dogs, nickel mining, and light pollution. == Taxonomy == In 1848, Peale collected and described the first specimen of this species in Tahiti. Then, in 1917, the Tahiti petrel was separated into two subspecies: rostrata and trouessarti, due to trouessarti's more robust bill. Not only is there a physiological difference between the two, they are also found in different geographic locations. P. r. rostrata, the nominate subspecies, breeds in the west-central Pacific Ocean whereas P. r. trouessarti breeds in the tropical and subtropical Pacific Ocean. Also, after originally being classified as Pterodroma, genetic studies showed that the bird is instead a part of the Pseudobulweria genus.…
