The Bornean Spiderhunter (Arachnothera everetti) is a fascinating, small passerine bird endemic to the island of Borneo, belonging to the Nectariniidae family, which also includes sunbirds. Measuring around 12-14 cm in length and weighing a modest 8-12 grams, this species exhibits a relatively subdued plumage compared to its often more vibrant sunbird relatives. Its most distinctive field marks include olive-green upperparts, plain greyish-white underparts, and a short, strongly decurved blac...
Primarily inhabits montane and submontane evergreen forests, favoring forest edges and clearings within its elevational range. Typically found between 800 and 2,000 meters above sea level, though occasionally observed at lower altitudes.
Feeds primarily on nectar, using its long, decurved bill to access floral rewards, and supplements its diet with small insects and spiders gleaned from vegetation.
Bornean Spiderhunters are diurnal and highly active, spending their days foraging solo or in pairs amidst the forest canopy and understory. Their foraging strategy involves dexterously probing flowers for nectar with their specialized bills, often hovering like hummingbirds, and gleaning small in...
