Evader of the snow dump

We had a snow dump last Thursday night.

We were greeted with 14 inches of snow on Friday morning, and it was still coming on strong.

That meant I couldn't get away with just making the fire and disappearing in the computer room the rest of the day.

When the redhead came in the house after an hour of shoveling I thought it prudent to inform her that I was just about to boot up and shake the snow off the trees.

"There's an owl in the Lady Banks' rose," she said, "so you probably don't want to bother it."

I  opened the back door and there it was peeping at me through squinted eyes.

The rest of the day it perched on the trellis under the eaves of the garage, but when the redhead checked at 5:00 it was gone.

It was back on Saturday morning, this time snoozing in the ash tree 15 feet from the house.

 The owl had the wisdom not to sleep under snow-loaded limbs, but what does it all mean?

 Why didn't it make use of the screech owl boxes near by?

I have one box about 40 feet from the house -- newly wired for surveillance, and another one 120 feet from the house, which has been used at least once in the past. 

Is there a girl owl in one of those boxes?  Is this the chivalrous mate?

When the snow melts I'll have to hook up the surveillance cam.
