Henderson Reed Warbler (Acrocephalus taiti) [XC97599]
     by id from Henderson I., Pitcairn Group, UK, United Kingdom (song)

Subspecies
No subspecies.

Acrocephalus vaughani (Sibley and Monroe 1990) has been split into Pitcairn Reed-Warbler (Acrocephalus vaughani), Rimatara Reed-Warbler (Acrocephalus rimitarae) and Henderson Island Reed-Warbler (Acrocephalus taiti) following Sibley and Monroe (1993). Note that Collar et al. (1994) followed Sibley and Monroe (1990) in treating these three taxa as a single species, Pitcairn Reed-Warbler (Acrocephalus vaughani).

Has been treated as conspecific with Rimatara Reed-Warbler (Acrocephalus rimitarae) and Pitcairn Reed-Warbler (Acrocephalus vaughani), but basic differences in sequence and pattern of leucistic plumage among the 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.
