Orthotomus chloronotus
The Green-backed Tailorbird, *Orthotomus chloronotus*, is a diminutive and often elusive passerine endemic to the island of Borneo. Measuring a mere 10-12 cm in length and weighing around 6-8 grams, it boasts a distinctive rufous-chestnut crown, bright olive-green upperparts, and clean white underparts, sometimes with a faint yellowish wash on the flanks. Its short, often cocked tail is also olive-green. A key field mark is its plain face contrasted by the striking crown, distinguishing it fr...
Found primarily in the understory and lower canopy of tropical moist primary and secondary broadleaf forests, as well as forest edges, from lowlands up to 1,500 meters (occasionally higher) in montane regions.
Primarily insectivorous, feeding on a wide variety of small insects and their larvae, spiders, and other small invertebrates. Forages actively by gleaning prey from leaves and branches.
