After spending some time with this fellow I believed he realized that I meant him no harm and he settled down to actively hunt.
Watching them tilt their head from side to side and up and down and pause to listen for movement under the snow is an amazing sight to witness.
This time he leaves the perch more in my direction rather than away from me...only to come up empty handed.
This continued on for a couple hours with two glides into the ditch in search of food.
