African elephant Swazi’s due-date range, according to all our calf data, was to fall between July 25 and August 24. We can see that the baby is situated mostly on her right side and is still up high, so physically we don’t see any changes yet. We get and send in her daily urine samples to our lab here at the San Diego Zoo Safari Park, with a turnaround time for results about two days later. Her progesterone levels haven’t dipped down below a number consistently with what we’d consider pre-labor (2 to 4 days away) levels. Regardless, baby will come when baby will come!
It looks like it won’t be this week at least. Schedules, staff, and volunteers are all on standby; we just don’t want to start too early and get burned out like we did with Umngani’s first (way back in the day). If we don’t see anything happening soon, I might start night watches anyway, because I’m getting antsy myself!
We did miss Luty and Tsundzu’s births (Emanti’s didn’t count because we were busy with Mac’s night watch), so births can come on rather quickly, and I’d like to try and film the birth for research purposes if we get lucky enough and there’s some light to see it. We may get lucky and see her drop her mucus plug or actually see the water break, but that’s been very rare for us, since most births have been under darkness.
Swazi is still nursing Macembe, so he’s in for a rude awakening soon. Since she is the dominant female, this being her second calf, and we’ve had three born out in the main east yard, we’re not overly concerned if Swazi were to give birth out in the main east yard. Having her give birth in the holding yard allows for filming, better observations, safety, and simpler separations away from others if we feel they might hinder her bonding time or if we have to intervene. I think Macembe will be the only one in with her this time. I’m sure they wouldn’t want to be in close quarters with her anyway—she’s pretty bossy!
Gotta go. Busy, busy busy.
