Bird Feeder

In school Courtney made a bird feeder. She was so excited to set it out and have the birds come eat it. We set it on our railing outside, and she got her stool and sat in the kitchen window and waited....and waited...and waited some more. I finally talked her into just checking on it later, so she got down. She then would all the sudden say, "I hear a 'Caw', a bird is here" and she would run back to the window and nothing was there. No bird has visited her feeder all day. As a parent this is absolutly heartbreaking....
