I have a bird at my feeder and I don't know what it is. It looks like a cardinal but it has a black head (no pointy crown either) and a yellow beak. My husband thinks it's tail feathers are longer then a cardinals as well. It doesn't appear to have a mate. Could it be a juvenile cardinal? It's size is full grown. I saw it at my feeder three times today but it could have been coming often because at first glance it looks like a cardinal.
