@DelacoursLangur The breeding bull is only 54 years old Thai. The other young bulls are related to the herd of cows. I hope they will soon import a new breeding male. Tupelo is almost nine years old and could have a calf, but Thai is her father and the other young males are either her siblings or half-siblings. Maybe they are planning to get a new breeding male only after the death of Thai, who is probably the oldest elephant bull in North America (correct me if I'm wrong).
@Elephantelephant You are right, Thai is the oldest Asian elephant in North and South America, he is also the largest. He is widely known to be the size of an African elephant while still being of the Asian species.
