MAGENTA PETREL Pterodroma magentae CR

AEstrelata magentae Giglioli & Salvadori, 1869

MZUT AV6689; mount; unsexed adult; southern Pacific Ocean, 39°38’S, 125°58’W, 22 July 1867; collected during the Magenta voyage .

Remarks.—The holotype of AEstrelata magentae Giglioli & Salvadori, 1869, which species went unobserved for a century following its description (Crockett 1994, Imber et al. 1998). Although the population of P. magentae is slowly recovering, the species is restricted to a single colony of 150–200 individuals on the Chatham Islands, east of New Zealand (BirdLife International 2018). Specimens are very rare in museum collections: in addition to the holotype, Te Papa Tongarewa (Museum of New Zealand) holds an adult male and a juvenile (https://collections.tepapa.govt.nz/topic/2802) and the Canterbury Museum, New Zealand, a fourth specimen (Pacific Ocean, ante 1910), misidentified until 2008 as Tahiti Petrel Pseudobulweria rostrata (Lawrence et al. 2008) .
