Perch is fine. In fact, finding an Orchard Oriole anywhere except the end of a branch would be tough. They seem to like to perch in the very tops of trees or out at the end of branches.
2 things I would do since you asked for critique.
1) as others said, open the crop up a little so there is more room around the bird, especially to the left and above as has been stated,
2) I would brighten it up a little. Orchard Orioles are kind of a burnt orange in the breast which is accurately reflected in your image. However I may add a little brightness, brilliance, vibrance, etc. Play with the sliders and see how it renders. Be careful as I'm sure you know, a little slider goes a very long way.
Overall, beautiful bird, well captured and a pleasing image. well done.
