Pisorhina sulaensis

E. J. O. Hartert

Mangole, Sula Islands

.

Probably part of a species-group centred on O. manadensis (which see). Until recently treated as conspecific with O. manadensis, but vocally very distinctive (based on recordings on xeno-canto and AVoCet—where split—subjectively allow 4), “considerably larger”#R (allow 2), and tarsus bare for “three-eighths of its length” (2); it differs from O. mendeni in its distinctive voice (song similar, but given in rapidly repeated sequence, recalling dove, fide recordings on AVoCet; score 3), much larger size (male wing 170 mm vs 141 mm#R; score 3), less feathered tarsus (allow 1), and evidently more boldly marked plumage (allow 1). Morphologically appears to be closer to O. magicus. Monotypic.

Distribution:

Sula Is (Taliabu, Seho, Mangole, Sanana), E of Sulawesi.
