Newest Back Yard Buddie

Yesterday late afternoon I looked out the window to admire all my backyard friends...  earlier I had counted SEVEN squirrels running around playing, jumping from tree to tree and emptying the feeders as fast as I could fill them... also I was admiring all the colored finches in the bird feeders, doves, quail and other various tweetie birds.  As I glanced up in the tree there was this HUGE Owl!!!  The squirrels were still running around in the branches not too far from it, so I gathered he was not a threat to them.  I was crazy running around here getting my camera, which didn't have a memory card in it... then changing lenses to my largest one (which was locked in the safe)...  Amazingly by the time I got it all together he was still there.  I opened our upstairs bedroom slider and took a few - he was very aware I was there, notice the squirrels all hid though.  Then I came down stairs and out the door to try and get even closer....  I could tell he was getting nervous (or ticked off) hesitated, then took off over the field south.  I did get a few photos though.  Definitely the largest wild owl I've ever seen.
