Great-horned Owl immature almost like adult

Young immature owls look almost like adults. Today as I approached the valley where they've been living since I first saw them in April I noticed first one then the second immature fly off from a low branch down below in the valley to a higher diagonally to the right. One decided to fly back towards me as there were a gaggle of crows in the other direction harassing the first owl. So I had a very clear chance to get this series of photos. They don't stay put if I move around.
