Hi Robert, you are pretty limited if shot in jpeg. This looks like a big crop, image is a bit soft.
I would also clone out the twig directly below it's beak. I hope you get another chance at it.
Not bad for a quick shot but it does have that look of being cropped too much. I would try not to crop more than 10 % with a Powershot. You can improve this shot a lot by cloning out the branch closet to his beak all the way back to the green needles. I do think you handled the bg nicely... a beautiful wash of color! You might also try darkening the green needles so they blend a bit better with the darker bg. Also try to keep your shutter speed equal to or greater that the focal length( 250 mm) . One more thing...start shooting in Raw so much easier to work with in post processing and Raw has more color gradations. Try it! I don't think you will ever go back to jpeg.
