It's hours now since Sunset, so at first I can't quite make out what's moving in the back yard.
Whatever it is, it's big, the size of a very large cat—an overweight cat, to be sure—but it's way too low-slung to be one of the neighborhood toms that regularly patrol my yard, and besides, the movement is all wrong: a kind of waddling scuttle.
A raccoon? We had one living up in the eaves a few years back: a big old, well-fed urban raccoon. (I opened the blind early one morning to find it giving me the Look: Just who the f*ck are you, and why are you wasting my time? Raccoons are notoriously attitudinous.) But no, the shape is wrong.
It crosses the yard and heads back to the compost heap by the garden. When I see the long, bare rat-tail, I know immediately what it is. I didn't realize that opossums got so big.
Opossums, North America's only native marsupial. I'm guessing from the size that this one's probably a male. In that case, like all male marsupials, he's got a forked penis. That's pretty cool.
Witch-critters. Here in North America, if you can't get bear-grease to make your flying ointment, possum grease will do just fine, they say. Look out, Mr. Possum.
