Baby Cardinals All On Their Own and Thriving

This is follow-up to the status of the baby cardinals born this spring. The second brood were born on May 24, 2012. They all lived. The reason I was not sure was because two of them were always together. They stayed and learned the ropes with papa cardinal. The third cardinal was learning with mama cardinal. We didn't figure this out right away. They are pretty much on their own now. Here is a pic of the baby I think from the first brood. I wrote about him/her too. When we noticed him he was already 4 weeks old or so. We don't know if he had any siblings or not. If he did they did not live because he was an only child when he first showed up here. I think this pic is of him. His black nose is starting to turn orange now. Plumage color is coming in too. I still don't know if it is a boy or girl.
