Hooters!!!

I've been watching a Great Horned Owl in a cavity since mid-February. 
I wasn't sure whether is was a nesting female, but after my encounter yesterday....we're going to have Owlets! 
I say that because yesterday, the female was in the cavity, and in a nearby tree was another adult Great Horned Owl. It's now apparent that the "watcher" is the male, who keeps watch over the female that is likely sitting on eggs or possibly minding Owlets. 
Here's some pics since first sighting the roost last month.
