Near Threatened

Zamboanga Bulbul (Hypsipetes rufigularis)


French: Bulbul à gorge rousse German: Rotkehlbülbül Spanish: Bulbul gorjirrufo

Hypsipetes rufigularis


, 1877,

Malamaui islet and Isabela, Basilan, Philippines


Previously placed in Ixos, but genetic data#R indicate that Philippine bulbuls placed in that genus belong instead in Hypsipetes. Often treated as conspecific with H. philippinus, but differs in its unstreaked rufous chin, throat and breast (2); clearer-cut break between breast and belly, with little or no grey on flanks (2); crown without paler edges, thus appearing darker (1); larger size (on wing length at least 2); song of lower-pitched (at least 2), slightly longer (at least 1) oriole-like whistles; no evidence of intergradation where ranges approach each other. Has previously been treated as including H. haynaldi (which was earlier listed as race of H. everetti). Monotypic.
