Recent findings (audit lane, verbatim)

Black storm petrel — The entry claims the black storm petrel feeds on 'spiny lobster larvae' as a preferred food, but established sources list its diet primarily as planktonic crustaceans, small fish, and squid, with no specific emphasis on spiny lobster larvae.

Black-winged petrel — The entry states the black-winged petrel nests across the tropical and subtropical East Pacific, but its breeding range is primarily in the South Pacific (e.g., Lord Howe, New Caledonia, New Zealand, Austral Islands), not the East Pacific; the East Pacific is

Black-winged petrel — The entry says the bird lives at sea in the East Pacific and comes ashore only to breed, but its breeding range is in the South Pacific, and it migrates to the East Pacific (e.g., between Peru and Hawaii) outside the breeding season.

Buller's shearwater — The claim that the species was never considered threatened with extinction is false; the population crash on Aorangi did lead to conservation concern, and the IUCN currently lists it as Vulnerable.

Christmas shearwater — The entry states the species nests on Sala-y-Gómez, but Sala-y-Gómez is a remote island in the southeastern Pacific (off Chile), not in the Central Pacific, and the Christmas shearwater does not breed there; its breeding range is restricted to the central and

Christmas shearwater — The entry says the species has become locally extinct on Wake Island, but Wake Island is still a known breeding site for the Christmas shearwater; it has not been reported as locally extinct there.

Cocos booby — The AOS has not recognized Cocos booby as a separate species as of 2024; it remains classified as a subspecies of the brown booby.

Cocos booby — The AOS has not officially changed the common name to Cocos booby, as the split has not been accepted.

Gould's petrel — The entry states that Gould's petrel was first described by John Gould in 1844, who named it Cook's petrel after James Cook; in fact, John Gould described the species in 1844 as Procellaria leucoptera, and the name 'Cook's petrel' was applied by Gould to a dif

Gould's petrel — The entry states that in his 1865 Handbook he changed the name to white-winged petrel; however, the name 'white-winged petrel' is not a historical synonym for Pterodroma leucoptera, and Gould's 1865 Handbook lists it as Oestrelata leucoptera, not 'white-winged

Great frigatebird — The entry states a male traveled 4,400 km from Europa Island to the Maldives, but the documented record is for a female great frigatebird.

Herald petrel — The entry states that in 2009, a previously unidentified Pterodroma species breeding on Round Island was identified as the Herald petrel, but it was actually identified as the Trindade petrel; the Herald petrel was confirmed to breed on Round Island in 2014, n

Herald petrel — The main text implies the 2017 chick on Raine Island was the first confirmed breeding ever on that island, but it was actually the first confirmed breeding in 30 years, as the species had bred there historically.
