Taxonomy and systematics

The Tenggara whistler is variably considered as either a subspecies of the widespread Australian golden whistler or treated as a separate species, but strong published evidence in favour of either treatment is limited, and further study is warranted to resolve the complex taxonomic situation.^[2] The name 'rusty-breasted whistler' was also used as an alternate name for the rusty whistler. With the transfer of the subspecies calliope from the yellow-throated whistler to the Tenggara whistler, on the basis of priority the scientific name changed from Pachycephala fulvotincta Wallace, 1864 to Pachycephala calliope Bonaparte, 1850.^[3]

Five subspecies are recognised:^[3]

• P. c. everetti Hartert, EJO, 1896 – Tanahjampea, Kalaotoa and Madu (southeast of southwest Sulawesi)
• P. c. javana Hartert, EJO, 1928 – east Java and Bali
• P. c. fulvotincta Wallace, 1864 – Sumbawa to Alor Island (west, central Lesser Sunda Islands)
• P. c. fulviventris Hartert, EJO, 1896 – Sumba (central south Lesser Sunda Islands)
• P. c. calliope Bonaparte, 1850 – Timor, Semau and Wetar (east Lesser Sunda Islands)

The Selayar whistler (Pachycephala teysmanni) was formerly considered as a subspecies.^[3]

Description

Compared to other members of the golden whistler group, the Tenggara whistler is relatively small, and males have a white throat and a rust-tinged chest, except in the subspecies teysmanni from Selayar Islands where the plumage of the male is female-like.^[2]

Distribution and habitat

It is the westernmost member of the golden whistler group, being bordered to the east by the black-chinned and yellow-throated whistlers, and to the south by the Australian golden whistler.
