Thalassarche melanophris impavida
Until recently considered conspecific with T. melanophris, but differs in its pale vs dark eye (3); generally greyer face (1); reduced area of white on underwing, forming relatively narrow white line within black (1); smaller size with a relatively shorter bill, published data#R indicating effect size 4.09 (2) yet slightly longer tarsus (effect size 1.33, score 1) and considerably lighter weight#R. Genetic analyses support treatment of impavida as a distinct species#R. Evidence of sympatric breeding with T. melanophris#R is inconclusive, amounting to mixed pairs reported on Campbell I#R#R. Monotypic.
Subtropical to Antarctic S Pacific Ocean, breeding on Campbell I (S of New Zealand).
