Interesting. The one is definitely a juvie, just getting his red top. I'm not sure if they change colors during breeding season like so many other birds. The ones we get up here the males tend to be the darker, brownish plumage and the females are grey. But that's based on limited observation during a very limited part of the year.
Another nice composition. I think the image is a little overexposed. May be you can reduce the exposure just a little bit and add some contrast and clarity , in order to bring out the colors and details on the birds some more.
