A small passerine bird in the white-eye family. It is a resident breeder in open woodland in tropical Asia, east from the Indian subcontinent to Southeast Asia, extending to Indonesia and Malaysia. They forage in small groups, feeding on nectar and small insects. They are easily identified by the distinctive white eye-ring and overall yellowish upperparts. Several populations of this widespread species are named subspecies and some have distinctive variations in the extent and shades of yellows in their plumage.
