That image was captured from a screenshot and put up on a Facebook Birding site as a "share the moment" thumbnail, and didn't yet have the level of post processing up to UHH demanding standards.
Part of what you are seeing as softness may be motion blur of the birds head as it flicks out the chips. It was so fast that I couldn't even see any movement then. Here's one with some Topaz applied. I think it's better.
I watched a pair of Red-headed Woodpeckers nest and raise one fledgling last season, and this spring RHWPs are back at the same tree.
There were three all flying around at one time, but now I believe two have paired up to nest.
The problem is they can't seem to decide on a location. Looks like it may be in the same tree, but this one started a new cavity just a couple of days ago. This photo was taken this morning.
