Rainbow-like Coloured Neck Feathers

I always wanted to photograph a pigeon, last time we went to a park and saw a bunch of them when i just got my camera, there were about 100 of them but i was just learning how to use it at time. I kept hitting the shutter but all the settings were wrong, when i got home i realized i didn't get a good shot of them. I was very upset :( That was the first time i see that many pigeons in my life and i screw it up LOL.

BTW, there's a few pigeons at my son's favourite park, so today i have tried to get a good shot of them flying and facing my way but no luck. So this will do for now. But i would really like to get a closer shot of its rainbow-like coloured neck feathers.

I love the way it opened its wings wide for me to capture its colour.
