How to Catch and Process a Quoll*

*and no ... we're not making sausages out of them ...


So how do you catch a feisty little marsupial, that's nocturnal and ground-dwelling and generally doesn't like to be caught?
Ecologists typically use baited traps, but of a sort that aren't likely to harm the captured animal - like this Elliott Trap, which has a door that springs shut when the animal steps inside.

Just before dark, our intrepid quoll-catchers set out the traps (with goodies inside) and then return to camp to give the quolls a chance to find - and take - the bait.


When a quoll's been captured, we take it back to the lab to 'process' it. Which sounds really suss but actually just means that we measure them and add tracking and identification devices to them. This is so we can obtain information about the health and size of the quolls, and keep track of particular individuals over time.




After we've taken all the important measurements, it's time to 'mark' the animals. In this study, we mark with ear tags, pit tags (like microchips), and collars - which may seem like overkill, but actually allows us to collect different kinds of data.


Ear tags are like earrings that have a specific number on them, unique to the animal. This means that if we catch this quoll again, we can easily and quickly determine its identity. Ear tags, toe tags, and leg or flipper bands (depending on the animal of focus) are commonly-used by ecologists for this purpose.


Pit tags are the second line of identification ... they're inserted under the skin, and hold all the relevant information about the animal - just like the microchip that you can get for your dog or cat. The coolest thing about pit tags? You read them with a scanner.

(as in, "clean up on aisle 3 ... ")


And collars - they're for the purpose of tracking the animal, using either radio frequencies or GPS (depending on the type of collar). By tracking individuals, ecologists can learn more about how the animals interact with each other, how large their range is, and how much they move around. If you want to know more, we talked about tracking koalas here and here.

After all this, the quoll is released back into the wild ... where it is no longer the anonymous little carnivore it once was.


So now you know how to catch and process a quoll. (Or, for that matter, any animal of ecological interest). Please use your wisdom for good, not evil.
