Another Question

When do Cockatiels usually go through their second molt? I have a male pearl who still has some of his pearling. I was told when I got him that he was one of last years babies. He is feeling his oats and is quite the little Romeo and has been through one molt so I figure he's over 6 months. If someone could give me a ballpark idea of when the second molt occurs I would have a better idea of his age.
