The Yellow-vented Flowerpecker or Dicaeum chrysorrheum is found in Bangladesh, Bhutan, Brunei, Cambodia, China, India, Indonesia, Laos, Malaysia, Nepal, Singapore, Vietnam and Thailand. Where I found this bird, Kaeng Krachan National Park, the habitat is just perfect since its natural habitats are subtropical moist lowland forests and subtropical moist montane forests.
Another Flowerpecker that I thought was not and the colours may not be bright but also unique as it is. This one did not stay for so long; hopped here and there and, gone. What I am curious about is, it has stripes on the belly and the yellow vent, plus the red eyes.
