I don't think necessarily that your hawk is young, just small. In fact, from what I can see in the pics, I *think* it is an adult Sharp-shinned Hawk. Check that out in your guide and let's also see what others say.
I was wondering if it might be a Merlin?
The long tail and short wings mean it's not a Merlin. I'm with Denis too.
My impression is the same as that of Denis.
