The yellow-vented flowerpecker (Dicaeum chrysorrheum) is a species of bird in the family Dicaeidae. It is found in Bangladesh, Bhutan, Brunei, Cambodia, China, India, Indonesia, Laos, Malaysia, Myanmar, Nepal, Singapore, Thailand, and Vietnam. Its natural habitats are subtropical or tropical moist lowland forest and subtropical or tropical moist montane forest. Along with D. melanoxanthum, D. agile, and D. everetti, it is often referred to as an “odd” Dicaeum species because of unique characteristics separating it from other species within the family. While most species have vestigial outermost primary feathers, those of the yellow-vented flowerpecker are elongated.
