A May Elephant Baby

Meet our newest elephant!

On the night of May 12, while the night-watch volunteers at the San Diego Zoo’s Wild Animal Park were doing the final week of watches on African elephant Swazi’s calf (born April 12, see post Newest Elephant Calf), Umoya decided it was time to have her second calf—one day earlier than a 21-month gestation (21 to 22 months is normal).

She didn’t give the keepers who were in that day any physical or behavioral signs that birth was impending, and her hormones had not dropped to birthing levels, so she was out with the rest of the herd in the main yard. The night-watch volunteer heard a big commotion (lots of trumpeting) around 8:15 in the main yard, and the elephants in the upper yards reacted by heading over to the cables and peering out into the darkness. It wasn’t until about 1:30 in the morning that Umoya and some of the others headed over to the cables where the lights allowed the night watcher to notice that Umoya had a little calf next to her. Seeing that Lutsandvo was next to his mother, Ndlulamitsi, it was now obvious that we had a new baby on the ground!

After some frantic phone calling, four of the keepers came in and were able to separate Umoya, Kami (her 2 1/2-year-old daughter), and her new calf into the upper yards to make observations a lot easier. The calf looked healthy, and successful nursing was soon observed. We also noticed that he was a boy. That makes all three calves born this year boys!

We never saw Umoya pass her placenta (which, according to data collected from all the other previous births we’ve had, normally occurs within four hours). As daylight approached, and the rest of the keepers came in, we moved the elephants around so that we could get access to the main yard. We scoured the main yard a couple of times, but we never found any sign of a passed placenta. Meanwhile, Umoya was nursing her calf, and for the most part, everything was fairly normal. He weighed in at 220 pounds (100 kilograms) the first morning. He lost a few kilograms the next day but was back up to birth weight by his fifth day. All of this was normal, as well as his total minutes of observed nursing during this time.

Our concern was mostly focused on Umoya because of her retained placenta and the complications that it could lead to. Giving her hormonal therapies over the first week didn’t produce the desired results we hoped for. Leaning on the experience gained from past experience, and in collaboration with our veterinary staff, it was decided to intervene and remove the placenta on May 21. With a procedure that involved a lot of different departments working together, and experts in various fields of study, the placenta was successfully removed through an incision just below her tail. It really couldn’t have gone more smoothly than it did, a credit to all the professionals in this organization who are truly dedicated to the animals under their care.

Mom and calf were soon reunited, and we continued to keep close watch on both of them. The calf started to lose weight over the next four days, so now our concern focused on him. His nursing totals were still very good: Umoya looked to be producing milk, and we expressed milk daily to make sure. But was it enough? The calf’s behavior also appeared more lethargic. If things continued in this trend, we were prepared to intervene if needed, from trying to supplement with bottle feedings to pulling the calf and hand rearing it.

Well, on May 25, he gained a kilogram in weight. He also looked better behaviorally. The next day he gained another kilogram in weight. Every day he gained a little more weight and looked better each day as well. He currently (as of June 1) weighs 225 pounds (102 kilograms)! Things are looking up for both of them. We even put Kami back in with Mom and calf during the day while the keepers observe them. We had to separate Kami temporarily: she was so persistent with trying to nurse off of Umoya that her mother would eventually give in, especially when she wasn’t feeling so well. We couldn’t afford to have Kami steal her brother’s milk, especially when it was imperative that he gain weight. She really is the “spoiled” child! Anyway, Mom seems to be able to keep her firstborn at bay now and dedicate her milk exclusively to her new son, so we’ll probably put them back together for good soon enough.

What’s the new guy like? Man, does he love water! He’ll guzzle it right from a hose and doesn’t care if you give him a bath while you’re doing it! He thinks his dad, Mabhulane, is pretty cool; he tries to nurse off of him like the other two youngsters do.

Sorry this post took so long getting out to the elephants’ adoring public. We’ve been very busy and not sure how this saga was going to play out. We hope to see you at the Wild Animal Park for the African Summer Festival celebrating these elephants!
