These are olive-backed sunbirds.
The adult bird moves quickly at this point so it's a challenge to take a photo. I don't know if the adult bird is a male or female. I don't want to assume. You can see the adult bird on the left side of the photo and it has food in its beak.
I have entered this in some contests as well here in steemit before.
These photo was taken in a tree in one of the trees surrounding the pool in a hot spring resort here in our place. I was resting under this tree when I heard incessant chirping that made me curious as to where it was coming from. I looked up and saw this the adult bird. I did not see the nest right away.
When I did see it, I hurriedly got up and took my camera. I used Nikon D5000 for this.

I used steepshot for this post because this is the only nest photo that I have for now.
