I saw this juvenile Great Horned Owl moving around before he saw me, so I was able to get pretty close to him before he flew.

He flew over to a cottonwood with a broken branch.

He watched me as I walked up closer to where he was perched.

Once I got close enough, he eyed a new spot to fly to.

From his new spot deeper in the bosque, he looked back at me with a "Don't you ever give up dude?" look.

This shot was taken right before he flew off into the trees where I couldn't see him.

This shot is for reference, as this is how dark it was, and what I could see with my naked eye and through the viewfinder. I set the camera so the recorded images are much lighter and more detailed than you see here, and then I process them and crop them in Camera raw to get the exposure, color and detail to look as good as I can get it to look given the limitations of ISO 3200 under very low light conditions.

The sunset from yesterday evening.

The sunset tonight.
