This picture is take from my village in Gujarat, India. I think it is a small bird which I have never seen before. It is smaller than an Indian hummingbird and even smaller than a neem tree leaf. You can see the leaf and the flowers. That flower's diameter is maybe a half inch so you can see how small the bird is. This bird has a very little trunk like a butterfly. You can't see this in the picture, but I saw it. This bird sucks liquid from flowers by that trunk.
Great picture and great find. But unfortunately I don't think that is a new species of bird...or even a bird at all!
It looks like a hummingbird hawk-moth, Macroglossum stellatarum.
Here you can really see the 'little trunk' (as you described it) known as a proboscis, which it uses to feed on flowers.
Fun fact: It's believed not to be a mimic of the hummingbird, but rather an example of convergent evolution.
