Sorry dragon, but your information is again wrong and misleading. Can you please get the facts right before posting??
Ringling`s breeding females are never performing, but living permanently in the breeding/retirement facility in Polk City, Florida. I just checked the studbook (which can be found online) and the database from asianelephant.net, and 5 of the 6 females which bred in the last years have not travelled in a long time and are having calf after calf. Only one, Bonnie, was inseminated by AI while she was on tour and then returned to give birth and raise her calf (Obama, the last calf born at Ringling`s). I have no information if she will stay there to be bred again, or if they will sent her on the raod again, or maybe if they wnat to breed her again by AI while she is travelling. I doubt you have any information on this, neither! If you want to say with your message that Ringling is not breeding all its females in breeding age and could produce more calves, well, then you are correct. There are serveral females in prime breeding age (or who have been in prime breeding age until recently) who are performing and never had the opportunity to breed. But what you wrote above is incorrect.
I am glad that Ringling is not producing even more calves, though - breeding baby elephants to take them away from their mother long before they are weaned, subject them to circus training and chaining and then dragging them through the country for the only purpose of making money and entertaining humans is a terrible thing.
