Bulbuls (Pycnonotidae)

Yellowish Bulbul (Ixos everetti) - HBW 10, p. 235

French: Bulbul d’Everett German: Everettbülbül Spanish: Bulbul de Everett
Other common names: Yellow-washed/Plain-throated/Everett’s Bulbul

Taxonomy: Criniger Everetti Tweeddale, 1877, Surigao, Mindanao, Philippines.
Taxonomy unsettled. Races are geographically variable in both morphology and voice; haynaldi in particular seems well differentiated, and has previously been placed with I. rufigularis. Proposed race samarensis (from Samar) indistinguishable from nominate, and considered better synonymized with it. Full review, including genetic analysis, and investigation of vocal variation based on adequate sample, is required in order to ascertain whether more than one species involved. Three subspecies provisionally recognized.
