Nice pics of the Bunting and Cardinal.

I have not been lucky in getting the Indigo Bunting's into a good pose this year...they want to feed in the grass and not use my perches for some reason.

I think you will enjoy Topaz AI Sharpen (also AI DeNoise is phenomenal)

In your image I selected only the bird and applied the filter to it so as not to disturb the background.

It has the ability to enhance focus, remove slight blur and also to sharpen.

It is easy to use and the results are impressive.
