Bulbuls (Pycnonotidae)

Streak-breasted Bulbul (Ixos siquijorensis) - HBW 10, p. 234

French: Bulbul de Siquijor German: Schieferkopfbülbül Spanish: Bulbul de Siquijor
Other common names: Slaty-crowned/Mottle-breasted/Siquijor Bulbul

Taxonomy: Iole Siquijorensis Steere, 1890, Siquijor, Philippines.
Taxonomy unsettled. Race cinereiceps is vocally, morphologically and behaviourally rather different from others, and likely to merit treatment as a separate species. Nominate race and monticola are more similar to each other, but differences may exceed those usually acceptable at race level. Thorough review of species limits necessary. Three subspecies provisionally recognized.

Subspecies and Distribution:

  • cinereiceps (Bourns & Worcester, 1894) - Tablas and Romblon, in C Philippines.
  • monticola (Bourns & Worcester, 1894) - Cebu.
