Thanks all, for the comments. Being a nooob, it's good to hear what I've done right and especielly what needs improvement.
I keep watching and hoping to repeat #4, and get it right next time. The blackbirds seem to chase the hawks frequently, but it's been behind trees, so no new shots.

With regards to the back-focussing issue.. If it wasn't user error, wouldn't it back-focus on every shot!?! Just curious, as i have no idea about this, but i DO get a lot of OOF shots lol!

Sorry for the bad humor, Back-focusing was meant to be a joke. There was a thread in the Lens forum a while back, where the back of ducks and what not was accused of being back-focusing, in humor because of all the back-focusing lens issues people were bringing up.
My lens is focusing just fine, all fuzziness is user error.

Here's another quick series of the same hawk, which I found funny. The wife didn't appreciate it as much as I did
