Proirie Warbler

Great shot of the action.  The bird is nicely framed by the surrounding branches and leaves.

While I like the position of the bird and the berries, the image is extremely soft.  Looks like focus may have been achieved on the leaf just below and to the left of the bird.  Images like this just have to be sharp.

Wonderful pose and composition, Robert.  To my eye, the warbler looks just a tiny bit soft as if the focus was on the leaf underneath the bird.  Did you have more than one AF point active?  It's easy for the system to get confused in a busy setting like this.

That's a great capture, with the tongue visible, but I agree with Keith and Dennis. Most avian photographers use a single point for focus, and then put that focus point on the eye. 

A great pose , if a little soft.Try a free trial of Topaz "Clarity" or "Perfectly Clear" - they may be able to help. 
Great image well  worth attempts to improve.

I'm sure others disagree, but for my particular camaera and it's sharpest  F stops, I'd go with F11 for shots like this with things in different focus planes, even if close together.

If you want to try it out.

Interesting behavioral image with nice framing of the subject.  The berries add a splash of color and interest.  Not quite sharp enough.
