Our male Golden Lion Tamarin's baldness is a sign that he is a good father. His hair loss is from transporting babies and being groomed by his family. The veterinary staff has performed a full exam on him and he is in good health. Most of his hair will grow back when he is no longer carrying around babies, but he will always be a little bald due to the grooming by the rest of the group.We just thought this was great! Good father = baldness. I'd also like to set the record straight by clarifying that although Chris is bald, he is in excellent health. So should we anticipate that Chris's hair will grow back when all our babies are grown? I doubt it. If he had hair at all, I'm sure by then it would have turned grey from dealing with teenagers.
