One of the big mysteries to me is which owl is which.  In past years, I could tell the difference between the two individuals and identify the sex of each based on their behavior.  This year they appear to both be red-phased owls and I have not been able to identify any significantly different features.  Here is (I hope) the video that I tried to post a couple of days ago of the two together in the box.  This, by the way, is the only time I have ever seen both owls together for long periods of time.  In this case, the top owl as you are looking at it was there when the sun came up, the other owl joined during the daylight--I think in response to a marauding Cooper's Hawk that scattered the feeder birds about the same time.
