Roo Confusion

The trouble with identifying kangaroos around here is mostly that whenever I see one, I’m so surprised that I forget to figure out what species it is. You’d think it would be obvious, like one is big and red (right, the big red kind, Macropus rufus) and one is little and gray (Macropus robustus), but some of the big red ones are just small because they’re young, and some of the wallaroos, also known as Euros, are actually sort of reddish and can get to a decent size.

As far as I can tell, in photos where I don’t get a lot of scale and can’t necessarily recall the roo’s relative size to my own (reds get 6 feet tall and up to 200 lbs, while common wallaroos only get 5 feet tall and 150 lbs maximum), I can separate the two by bulk (reds seem to have larger, more muscular arms relative to their bodies, but also generally heftier bodies compared to their heads) and comparative ear size (though that’s just conjecture, since ear size might have more to do with age or individual variation*).

Kangaroos tend to live in larger “mobs,” somewhere around ten usually but in poor conditions can gang up into the hundreds. Wallaroos are mostly solitary, according to the internets. This information is not really supported by my own observations, but let’s be real- I mostly see these guys while either I’m running or they’re running, so I can’t say that any of my surveying has been at all scientific.

Mostly I’d say the main difference between a kangaroo and a wallaroo is that turning a corner and finding myself too close to a wallaroo is adorable, and doing the same with a kangaroo is just a little bit terrifying. Imagine a rabbit the size of your dad, and then give it muscley arms (the rabbit, not your dad).

…Have fun with that one. Here’s a reminder that macropods can also be really cute:

Sleep with dreams of fuzzy baby ‘roos and try to get that image of your rabbit-dad out of your head. Oh, too late. Sorry.

*Did you know that human ears and noses keep growing forever? Like through your whole life (I’m assuming if you’re reading this you’re human, but to any intelligent dolphins or aliens reading this: um hi please email me) your ears will get bigger and bigger. If you could live forever maybe you could learn to fly Dumbo-style. Or at least swim like a manta ray. It’s all cartilage, right?
