Whitehead's spiderhunter Arachnothera juliae

Unique to the Bornean highlands, this remarkable and highly-sought-after spiderhunter, with its bright white streaking and yellow rump, is utterly unmistakable. Forages actively in the canopy, often singly or in pairs, but sometimes with mixed flocks, frequently probing into flowers and mossy vegetation. Gives a clicking nasal call, “bu’chuk-yih-WEEEE”, or just the nasal “WEEEE”.
