equatorial regions of Atlantic Ocean

.

In past, often lumped with F. grallaria; relationships between these two are complicated and confused, especially at Tristan da Cunha and Gough I; proposed race melanoleuca (Tristan da Cunha) may be invalid or may be referable to F. grallaria. Considerable individual variation in plumage tends to obscure geographical variation in this complex; most forms described as races are usually ascribed to F. grallaria. Monotypic.

Distribution:

Tropical and subtropical major oceans; circumpolar breeding, from islands of Scotia Arc through S Indian Ocean to Antipodes Is. Possible presence at Tristan da Cunha and Gough I requires confirmation.
