The tropical shearwater (Puffinus bailloni) is a seabird in the family Procellariidae formerly considered conspecific with Audubon's shearwater (Puffinus lherminieri).[2]

Subspecies

There are five listed subspecies of the tropical shearwater:[2]

Puffinus bailloni nicolae – (Jouanin, 1971): breeds on islands in the northwest Indian Ocean.
Puffinus bailloni colstoni – (Shirihai & Christie, 1996): breeds in the Aldabra Islands in the Seychelles.
Puffinus bailloni bailloni – (Bonaparte, 1857): Mauritius, Réunion & Europa Island.
Puffinus bailloni dichrous – (Finsch & Hartlaub, 1867): Central Pacific islands.
Puffinus bailloni gunax – (Mathews, 1930): Vanuatu.

Range

The tropical shearwater is found in the tropical parts of the western Indian Ocean from east Africa to southern India and in similar regions of the Pacific from just to the southeast of Japan to French Polynesia.[3][4]

Population

The total population has not been definitively quantified. Subspecies P. b. dichrous is estimated to number 1,000–10,000 pairs on the Line Islands and 10,000–100,000 pairs on the Phoenix Islands, with the nominate subspecies thought to number 3,000–5,000 pairs on Réunion and fewer than 100 individuals on Europa (reviewed by Brooke 2004), though it is thought there are many more breeding colonies on other islands in the Pacific. The population seems to be stable.[5]

gollark: No idea.

gollark: The flash stuff degrades, but it can correct for it to some extent (and report issues to the OS), but might also randomly fail for no apparent reason.

gollark: From back when they cost about 4 times as much as now.
