I like the behavior of the first shot. Anytime you can take a shot of wildlife actually doing something interesting or behavioral...it always makes it better.
With that said, here are a couple tips if you don't mind. I have others, but I don't want to over complicate your next attempt. One of the most important things to me when shooting wildlife, is getting the subject to pop and eliminate most of the scene which can distract the viewer for what is happening. So a good rule of thumb is to look for a clean background. In both of your images, you have a lot of leaves and branches which compete for attention in the scene. My second tip is make sure of your focal point. On the first image, your focal point seems to be on the berry at the bottom of the birds feet and because of this, the eye is a bit soft. You can eliminate some of this by using a smaller AP to extend your DOF, but then you are possibly introducing more detail from the background that you don't want. The eye is always one of the most important things to have sharp in most any wildlife image. Like I said, there are many other things, but hopefully this will give you a couple of things to work on for your next image to make even further improvements.
