Least Concern

Rufous-sided Honeyeater (Ptiloprora erythropleura)


Taxonomy

French: Méliphage à flancs roux German: Rotflanken-Honigfresser Spanish: Mielero flanquirrufo
Taxonomy:

Ptilotis erythropleura

Salvadori

Arfak Mountains, north-west New Guinea

Formerly considered conspecific with P. guisei, P. mayri and P. perstriata, but the four differ in size, plumage (crown colour, dorsal coloration, colour of wing-covert edgings, distinctness of ventral spotting, flank colour) and iris colour. Present species sympatric (and with broad altitudinal overlap) with P. perstriata over distance of at least 400 km in W New Guinea. Birds from Wissel Lakes area (between Weyland Mts and Snow Mts) described as race incerta, but validity unclear and may represent a hybrid form between race dammermani and P. p. perstriata; further study needed. In NW (Bomberai Peninsula), Fakfak and Kumawa birds#R resemble dammermani in having green irides (red in nominate of Arfak and Tamrau) but differ in yellow-olive ventral wash and (some, not all individuals) rufous flanks, also vocal differences (some calls with two-note or three-note pattern, high-pitched, plaintive, and monotonously repeated); both populations provisionally included in nominate race, but more study required in order to determine whether they represent one or two undescribed races, or even new species. Two subspecies currently recognized.
