It's an automatic delete. Why? Well, for one thing the sky is blown out. You never EVER want blown-skies in your shots. Cover them up by juxtaposing an element over it. Maybe change your angle or perspective so that the sky is no longer in the shot. Or maybe you just do not take the shot because you know that a blown-out sky will completely kill the shot.
I would have taken the shot at a much higher angle. This would have achieved a few things. First, I would have been able to avoid having a blown-out sky in the shot. Instead, I'd have the desert as a background which infinitely more interesting than a blown-out sky. Second, I would have been able to set up the composition so that the bird wasn't obscured by the bird. Thirdly, at a higher position, the camera would have been at eye level with the bird, which might create a better perspective as opposed to looking up at the bird.
The cactus is a cool looking plant as is the bird. However the parts of the cactus are very busy which make for a messy composition. Furthermore, the bird is being obscured by the cactus.
On a technical level, the cactus in the foreground is out of focus. Either use a larger aperture to completely blow it out of focus or use a smaller aperture to get it all in focus. What you absolutely do not want to do is to go part way because it looks like a mistake as it does here in this shot.
You should have also used fill flash which would have added catch light in the bird's eye. Catch light will add an enormous amount of life to the animal as opposed to have a dead, black eyeball.
You chose to shoot at a very nice time of the day. The golden hour light is really nice in this shot. However, the bird is looking away from the light which is generally not what you want. You should have waited for the bird to turn around. If that happened (it very well may not have ever happened, which is just part of wildlife photography), then the bird's face would have been illuminated with that great warm, golden-hour light. As is, the bird's face is in cold shadow which dulls it's colors. Adding a fill flash would have helped especially but only if you add a warming gel over the flash head which would have equalized the color temperature of the light from the flash with the warm gold-hour light coming from camera right - not to mention that it would've added a wonderful catch light in the bird's eye bring it to life.
