Mystery bird in El Paso

On Nov 9 I was sent these two photographs of a bird of prey, taken at a small water tank in a garden in El Paso:

The author of the pictures (Roger Ligter) requested help with  identification of the species. I was surprised by the amount of pink on the bird's plumage, and a better view of the breast would have been helpful. My final verdict, after seeking a second opinion from an experienced local birder, is that the mystery raptor is an adult Sparrowhawk (Accipiter nisus).
