Unidentified bird

Hi all, new here. Saw an unusual sight today at work. What appeared to be a kestrel chick being taught to catch bugs by a magpie. And the two were flying together. They both took off from the same spot, landed 20 inches apart, stayed together interacting on the branch. Then after about 6 mins they flew off together to a different tree out of sight. Any thoughts on the brown bird I have presumed to be a kestrel. Feel free to correct me Relaxed️ thank you. (When I can figure out how to post the image!)
