Zosterops fuscicapilla crookshanki
Mayr and Rand, 1935,
Goodenough Island, D’Entrecasteaux Archipelago.
Usually considered conspecific with Z. fuscicapilla, but recent discovery of population on Fergusson I reinforces case for species rank#R: differs from latter in its markedly broader eyering (2); silver-grey vs brown iris (3); less yellow, more olivaceous on rump and underparts (1); browner tail (ns); larger size (at least 1); and seemingly very different song on basis of published descriptions#R#R. However, this assumes iris colour is pale on Goodenough I; moreover, Fergusson birds have black crowns and head sides apparently like Z. fuscicapilla and unlike Goodenough birds, suggesting a link but also an undescribed subspecies. Monotypic.
