Purple-backed Starling

Okay the additional photos help a lot. I've attached a suggestion.

Liam, I've uploaded some more photos of the bird. The size is much bigger than normal sunbirds, so I don't think it might be a sunbird (compare to the drongo in the 3rd photo). The 3rd photo has six of those birds in a tree. I guess there r 4 males n 2 females. The birds in all the other photos seem to be females. Also in the 5th photo, you can see the bird moving to another flower in a running-like movement. As far as I've seen, sunbirds normally fly or jump to other flowers. The movement seems different too.

Looks like a female Sunbird, but I can't tell which species from this photo.
