honey and sting

We've been blessed, in the trees at work, with a great horned owl.  He mostly dozes during the day when we are there, but every once in a while preens his feathers, or rubs his head against the bark of the tree like a cat.  He's HUGE and very fluffy.  I've tried to take pics but he's too well camouflaged.

I'm told that the groundskeepers find pigeon heads in the morning.   I guess he's a picky eater?  I'm assuming "he" but I don't know how to tell.

Life just keeps opening up.
