Dark-crowned Heleia

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.

Medium-sized rufous-brown bird of lowland forests. Occurs mainly in understory and midstory of tall rainforest, often with mixed-species flocks. Also occurs in premontane forests in the tepui region. Climbs up tree trunks and along large branches, probing into crevices for insects. Similar to Buff-throated Woodcreeper, but slightly smaller and shorter-billed with richer coloration on throat giving overall darker appearance.

Tiny songbird of mountain and hill forests; ranges from the Himalayas south to the Malay Peninsula on the Asian mainland, with an isolated population in Taiwan’s highlands. Adult male is dark blue above and pale creamy white below, with a black stripe leading down the belly from a brilliantly red patch like a bloodstain on the breast. Female is much plainer, brownish-olive above and off-white below; lacks the bright white throat of Plain and female Scarlet-backed Flowerpeckers. Often forages at flowers blooming in the canopy. Gives a high, thin, up-and-down “tsee’ip, tsee’ip, tsee’ip” and a rising series of ticks (often ending with more metallic notes); calls include dry tick notes and high, thin “tseet”s.
