This is a chuditch or western quoll. He is having a kip.
This is a northern quoll, very possibly a juvenile northern quoll.
Northern quolls are the largest known mammals to undergo semelparity, in this case male die-off. Much like the more infamous antechinus, northern quoll males go into a mating frenzy and die from exhaustion. This particular instinct can be suppressed with measure such as isolating the male from the relevant female pheromones, or giving him the snip. Or, as one antechinus researcher discovered, accidentally having their knackers ripped off while escaping from a trap.
This is not a quoll but it is such a close relative that some of them have spots like quolls. It is of course a Tasmanian devil.
I’m not sure what to say about Tasmanian devils that hasn’t already been said – yes they’re real, no they’re not just cartoon characters, yes they’re only found on a pudendum-shaped island south of Australia for the time being, yes they’re in danger of dying out from a communicable cancer called Devil Facial Tumour Disease, no it’s not cured yet, yes they’re trying to cure it but Tasmanians are running over the vaccinated ones for some reason.
This is not a quoll but it is an Australian predator. It is a southern boobook owl, or just “boobook” for short.
Boobooks have a distinctive falling two-toned call. Like all hawk-owls, they often look annoyed or hung over.
Dibblers have been in the news recently – DPAW and Perth Zoo are doing a wild release down on a cat/fox-free island off the south coast of Western Australia.
This dibbler has a running wheel. I have video of the dibbler falling off the running wheel. Want to see it?
