As I was sitting in my car today waiting for my husband, I caught sight of two hawks riding the thermals just above me. They were swooping on something in shadow of the trees. Then, like a Valkyrie descending from on high a crow came down, and began to attack both hawks. The hawks fought back for a while, but they soon realized that the reward for their tenacity wouldn't be worth the price of an injury, so they disappeared. The crow landed in the tree, and although it had won it looked rattled. It preened itself shakily.
The crows here are brave. I saw another one whilst I was walking the dog, and it didn't move at all even when my dog rushed towards it. Of course, my dog only weighs 6lb, so he's not very imposing. The crow was bigger than him. Even so, I thought it would fly off when threatened by anything. I was wrong. I passed within two feet of it, and it watched me insolently with shining black eyes. It was beautiful and also somehow imposing.
I can see how people become fascinated by birds.
