Peacocks are LOUD! They run around everywhere at Atlanta zoo and always making such loud and annoying sounds, but easy to shoot.
The second shot is nice, but I think the image can be brighter in general to emphasize the colors. May be you can play with the saturation.
One side story. My coworkers and I were talking about nature's defense mechanism over lunch one day and one guy mentioned that the peacock species focuses on trying to impress its mates for the sake of procreation and evolved into this flamboyant form, but at the same time, becomes less and less defensive against predators. Then the other guy said that may not be true, cus the lions will have more feathers to spit out now, so it may not even be worth the effort.
