Old World Warblers (Sylviidae)

Pitcairn Reed-warbler (Acrocephalus vaughani) - HBW 11, p. 630

French: Rousserolle des Pitcairn German: Pitcairnrohrsänger Spanish: Carricero de la Pitcairn
Other common names: Pitcairn Warbler

Taxonomy: Tatare vaughani Sharpe, 1900, Pitcairn Island.
According to mitochondrial DNA sequences and morphology, this species is part of a monophyletic clade together with A. arundinaceus, A. orientalis, A. stentoreus and A. australis; probably other Pacific species also belong to this clade, but genetic data lacking. Has been treated as conspecific with A. rimitarae and A. taiti, but basic differences in sequence and pattern of leucistic plumage among the three taxa suggest substantial genetic differentiation at species level; as they are separated by great distances of open ocean, gene flow among them is..

Has been treated as conspecific with A. rimitarae and A. taiti, but basic differences in sequence and pattern of leucistic plumage among the three taxa suggest substantial genetic differentiation at species level; as they are separated by great distances of open ocean, gene flow among them is probably less than minimal. Monotypic.

Distribution: Pitcairn, in Pitcairn Is (S Polynesia).
