Postcard from Victor Harbor

Ladies,

Let’s have a talk about childbirth. I’ve never been pregnant, so I don’t know what it’s like to put your body through pregnancy and childbirth. Nor do I have 24/7 hands-on knowledge of what it’s like to rear multiple children. So maybe I’m a little more wowed about what our kangaroo counterparts manage to do when it comes to reproducing, but perhaps you might be impressed as well.

The above picture is adorable, right? The classic roo with a joey in her pouch. So cute! Baby with mama, hanging out until it becomes an adult. But that’s only one-third of the story, as I learned from one of the keepers at Urimbirra Wildlife Park. Here’s the rest of the story:

When a female kangaroo is able to have children, she gets pregnant. She has the baby, and the baby (called a joey) hangs out in her pouch. It may leave and explore the greater world, but it’ll hop back in head-first, giving mom this lovely look:

 

For which joey won’t apologize until two decades later when on Kangaroo Mother’s Day, it sheepishly gives mom a “sorry I made you look like an alien” card.

Anyway, after it dives into the pouch, it’ll turn around at some point to be able to stick its head out and look cute (and make it easier to get out), even if it’s getting bigger and is more to lug around. While mom is carrying around joey #1, she gets pregnant with #2.

Joey #2 is born. Joey #1 gets pushed out of the pouch, and joey #2 takes up residence there. Joey #1 is still kind of a child though, so it’s also still feeding on mom. Meanwhile, mom gets pregnant again, so she’s got a bun in the oven, a joey in the pouch, and another on the teat.

When joey #3 comes along, it’s time for joey #1 to make its own way in the world, so no more teat for it. Joey #2 moves to the teat. Joey #3 gets the pouch. And mom becomes pregnant again.

This cycle continues for all of mom’s childbearing years. Yes, for the entire time you can bear children, you’re running this cycle of three at pretty much any given point in the year. [To be fair, I was so blown away by this that I didn’t even think to ask whether or not kangaroos can miscarry or if some are infertile, and believe you me, those questions are definitely on my mind now that I’ve processed the basics. If you have answers, I am all ears.]

BUT WAIT, THERE’S MORE!

The female kangaroo also possesses some magical superpowers that can determine whether or not its joey-in-the-oven is getting enough nutrients, and if there isn’t enough food or water around to allow for proper incubating, pregnancy will halt and remain in suspended animation until there’s food and water again. At that point, pregnancy resumes like nothing ever happened.

Did you get that? The female can put its pregnancy on hold. On hold! What if you were 20 weeks along, and suddenly there was a drought and you couldn’t get enough food or water? Would your body just turn off the pregnancy until it rained again? Would you want to have some suspended animation action all up in your uterus for who knows how long?

You let me know because right now, the kangaroo has earned my mother-of-the-year award for life.

Your pal,

Jill
