Nuthatches are woinderful photo subject with lots of personality and color. Pose and the small diameter perch is place perfectly in the image. The subject is nice and crisp too. The whites are fairly bright and you might be able to pull some details from the highlights as my only suggestion. Well done…Jim
I think it works really well as a portrait of a pretty cool species (I was just commenting to someone this morning that I wished I had more nuthatch shots).
Everything technically is spot on in my book… the only minor nit has to do with that light patch to the right of the wood. It is a minor distraction, but is the type of thing that is hard to spot in the moment. With a second chance, a slight re-positioning of the camera to the right would presumably get clear of that.
My favorite elements of this image are the series of cracks on the left side of the branch, and the position of the feet: small details that really grab one’s attention while exploring the frame.
