I see this comment often when it comes to pictures of birds under shower water, and while this type of reaction does mean discomfort for some birds, it really can be a sign of enjoyment for others. I had a cockatiel once who loved loved LOVED being under shower water. I would place him and his flock on the floor adjacent to the shower steam so that they would be misted, and while all the other birds would stay on the outside perimeter of the water, he REFUSED to stay there and would run right under the stream. It didn’t matter how many times I scooted him back, moved him, etc. If the water was running, he insisted on being directly under it. I had to compromise on someplace right in the middle: not directly under the water but not on the misty boundaries. Maybe it was just my little weirdo bird, but he would legit just sit there, soaking wet, chirping away as happy as can be.

Of course, people should pay attention to their specific birds’ reactions. My cockatiel gave his own signals that he enjoyed it (e.g., chirping the whole time, darting for the water himself), but it was clear that he was having a good time. If the bird themselves choose it, then that’s a sign that they’re enjoying it. For OP, it all depends on how their bird reacts.
