Angry birds 2

On the way to check the nest, I passed 2 hawks sitting in a tree together. When I got to the nest, I still couldn't see any babies, but Mrs. (?) was on a branch nearby. I went back and since the other pair was still in the tree I pulled over and started taking some shots. At first I didn't realize that he was shrieking at ME. I saw him look, but I was so far away that I didn't think he would be upset about my presence. But he was. He took off twice, circled above me and then returned to the same branch to yell some more. I think the yeller was the male, as he was a little smaller. The female just sat on a different branch, looking back and forth between us. She left finally, and he came and sat on her branch. I've seen 2 hawks flying in this area while I was riding, but was never sure if it was the pair from my nest or a completely different pair as they are less than a mile apart. Maybe there's another nest?!
I love, love, love living here, and being able to see these birds on a daily basis. Did I say daily? I didn't mean daily.
