Cardinals at Bird Feeded

Our styling blue glass bird feeder is quite attractive to the neighborhood birds. Recently our camera snapped a couple of pictures of Cardinals at the feeder. But the first picture also shows a smaller bird waiting her turn at the feeder. She is hanging on the wire about a foot above the feeder so she can swoop down when the Cardinal moves on. This feeder is definitely a one at a time feeder so it isn't unusual to see birds waiting their turn.
