Yellow-throated Fiji whistler explained

The yellow-throated Fiji whistler (Pachycephala graeffii) is a species of passerine bird in the family Pachycephalidae, endemic to central Fiji. It was formerly considered to be conspecific with the white-throated Fiji whistler (Pachycephala vitiensis). Before the split the combined species were known as the "Fiji whistler".

Taxonomy

The yellow-throated Fiji whistler was formally described in 1866 by the German ornithologist Gustav Hartlaub based on a specimen collected on the island of Viti Levu in Fiji. He coined the binomial name Pachycephala graeffii where the specific epithet was chosen to honour the Swiss naturalist Eduard Heinrich Graeffe.^{[1] [2] [3]}

The yellow-throated Fiji whistler was formerly considered as conspecific with the white-throated Fiji whistler (Pachycephala vitiensis). It is now treated as a separate species based on the differences in plumage and vocalizations.^[4]

Seven subspecies are recognised:^[4]

• P. g. ambigua Mayr, 1932 – southeast Vanua Levu, Rabi and Kioa (east of northeast Vanua Levu; central north Fiji, southwest Polynesia)
• P. g. optata Hartlaub, 1866 – southeast coast Viti Levu and Ovalau (west Lomaiviti group; west, central west Fiji, southwest Polynesia)
