Medium-sized spiderhunter with an olive back and streaked gray underparts. Inhabits lowland and submontane forests and forest edges, where it feeds primarily on nectar in the understory; favors blossoms of banana and ginger. Very similar in appearance to Gray-breasted Spiderhunter; range overlap is poorly understood but appears to be minimal. Look for Bornean’s more intensely streaked underparts and slightly larger size. Long-billed Spiderhunter can show some streaking on the breast but is much larger and longer-billed, with yellowish underparts. Sometimes noisy, giving loud raspy nasal calls.
