ON the wood pecker shot, the chain and the highest bars of the cage look pretty sharp.
If you were focused on the bird you need a focus adjustment. I always use the eye to judge focus or sharpness. For me I only make these decisions without looking at a pixel peep near the eye.
This tells me if the lens is sharp, but it also tells you ig you missed focus. I always look for a part of the image that does look sharp. If part of the image is sharp but your subject is not,, it's a missed focus. If none of the image is sharp it may be motion blur. But it's darn hard to evaluate a lens from a web sized image, in any case.
It's hard tp say for certain without pixel peeping but your bird looks soft. But it also looks like a missed focus.
