Given the array of color presented by the male’s plumage the name seems appropriate: a pair of yellow bands on either side of a red chest, green on head and back, blue on the lower back and black on the belly and tail. The females are plumaged instead to be inconspicuous and safer from predators: yellowish chest and belly with gray-brown back. Beautiful sunbirds take flower nectar and insects as food. It is a very common species in arid and semi-arid regions of Kenya especially Samburu, Tsavo West,Lake Baringo and Amboseli.
They generally frequent flowering plants and therefore provide necessary conditions for photography.
Kenya Birding 
This bird was one of the memorable ones from my (too short) trip to Kenya. I hope I can come back to see more. In the meanwhile your posts keep me going.
You are always welcome Mr.Khanewala. We look forward to welcoming you back!
