FeedingFlower of the Coconut tree

Although this bird looks like a Yellow Bellied Chat, I dont think it is the case. Well if you can Identify the Species please let me know. Spotted this Sweet one, feeding on the flowers of the coconut tree in my backyard.
P.S. :Many visitors to the blog helped me identify this bird as Purple Rumped Sunbird. (Special thanks to Prasanth Narayanan
