We feed the crows every day with kitchen scraps, etc. They are amazing to watch. I can get to about 3 or 4 feet away from them before they hop away out of reach.
There are two who always seem to travel together, pretty sure they're male and female. My wife and I were sitting on the back porch watching them one day, the female was right in the face of the male, flapping her wings and squawking into his face. He just stood there calmly looking around not making a sound.
I said to Mrs. 48, "They gotta be married." She started squawking and flapping her arms at me.
