We don't get to spot peacocks that often. That too with their feathers open. We mostly see them in the confined environments of a zoo. Recently I happened to spot them in open, near our village.
Peacocks make a peculiar sound. When I heard this sound I walked towards the direction. Near the bushes adjacent to paddy fields, I found this peacock dancing with its feathers wide open.
Thanks to 300mm I could zoom this much standing very far from the bird so as not to alert it. But it is still not close enough.

With my Sony I could have zoomed further-sample below- check this post to view some more peacock images
