He watched him dive bomb and grab at something (most likely a mouse) in the grass. He didn't seem happy to have missed.
He then spent some time perched on one of the fence posts.
Finally Mountain Man was able to take some shots of him flying high above. He was quite angry at him for disturbing his hunt and spent some time flying in circles and yelling at him from above.
I love this shot! He obviously decided to take a closer look at who was taking such an interest in him.
Then off he went! Beautiful!
