Maps of the birds of the Western Palearctic Region

Pterodroma mollis
Pelagic, breeding on islands in burrows on steep slopes.
Is. in s Atlantic and s Indian oceans on Tristan da Cunha (incl. Gough), Kerguelen, Marion, Crozet (East), probably Antipodes.
Ranges at sea in Atlantic and Indian oceans n to lat. 25°S. It is unclear whether this species reaches the north Atlantic, although birds thought
to be mollis have been reported.

Pterodroma incerta
Pelagic, breeding on islands in burrows.
Tristan da Cunha (incl. Gough). Ranges at sea between s S. America
and S. Africa.

Pterodroma hasitata
Pelagic, breeding in burrows on mountain summits.
The two races are sometimes treated as separate species.
P. h. hasitata Highlands of W. Indies in Hispaniola, e Cuba, Guadeloupe, Dominica (probably extirpated), possibly Martinique.
Ranges at sea in Atlantic n to Maine and s to Brazil. Size variation in birds taken at sea suggests that additional breeding colonies may persist in the Caribbean.
P. h. caribbaea Jamaica (Blue Mts.), now probably extinct.

Bulweria fallax
Pelagic, presumably breeding on small islands.
Breeding range unknown, probably on coast of s Arabia.
Ranges at sea in Indian O. to lat. 5°S.; vagrant Hawaiian Is.
Sometimes treated as a race of B. bulwerii.
