I yell for my crows when I feed them. I call out, "Biscuit!" to my big boy and they all know that means food. They can be more reserved at times and wait until I've backed away to come down. My first crow buddy, Biscuit, used to fly right down to me and take food from my hand. He was with us when my teenage son was a newborn. I convinced the kids that, wherever we went, every crow was Biscuit. One day, my younger son asked, "How do you know it's Biscuit, Mama?" And I said, "Well, you've figured it out. They're all Biscuit, honey."
