This is a Lady Gouldian Finch - So Festive!
Now is the time to keep binoculars handy - we're seeing many new birds in the neighborhood. They're passing through, flocking down onto the grass, and indulging in much excitement and chatter. Photo, Birds Planet on Flickr.
Don't know where I saw this...but somebody had fun building it. (Cleaning it will be tricky.) One of the most pleasant sounds I ever experienced was listening to my two little hens talk to each other as they roosted for the night. One would face forward, the other backwards.
