Herald Petrel (Pterodroma heraldica)


Taxonomy

French: Pétrel du Herald German: Heraldsturmvogel Spanish: Petrel del Herald
Taxonomy:

Oestrelata heraldica

Salvin

, 1888,

Chesterfield Islands, western Pacific

.

Often considered conspecific with P. arminjoniana, but distinct in several characters relating to smaller size, pale facial markings and underwing pattern, plus different intestinal structure#R; despite a degree of apparent hybridization on Round I, off Mauritius#R, its specific status is here regarded as appropriate. Birds of Easter I sometimes placed in separate race paschae. Monotypic.

Distribution:

Tropical Pacific Ocean, breeding from Raine I (NE Australia) E to Easter I; also Indian Ocean, breeding on Round I (Mauritius)#R#R.
