We had baby sparrows outside our kitchen window. I saw a blue jay trying to get in their house. I opened the curtain and frightened him away. I looked it up on the computer and saw a video of blue jays stealing and eating the baby birds. Oh, it makes me sick even though I know God planned it this way. I always loved them. Our neighbor's beautiful black and white cat was in our yard checking out our birds: he was ready to pounce on one until I opened the window. We have a wooden fence around our yard but animals can get in if they try. We have two shih-tzus--that's the reason for our fence.
