More Possum Hollers

photo of a Brushtail PossumHere in Australia’s wilds, I seem to be a possum magnet. On a pristine-calm night in the Timmallallie National Park near Baradine, New South Wales, two different possums greeted, or rather threatened, me with growls and barks as they stumbled upon my camp in the dark of the night.

My first visitor appeared around 2am … a Brushtail Possum (Trichosurus vulpecula), the largest of the Down Under possum clan, weighing up to 10 pounds (4.5kg). His loud, gruff growls shook me from sleep as I laid there on my tarp, wondering if I should be concerned:

The Brushtail is nocturnal and semi-arboreal. Listen carefully, you can hear him running on the ground at the beginning of the recording. My guess is that he growled when he suddenly caught my scent, or else saw my tent looming in the darkness (Carl Gerhardt, my traveling companion, slept a few hundred feet away and he too had one growl at him in the night).

He probably glided to a tree near my tent and then voiced his disapproval with measured yaps or barks (frog sounds can be heard in the background):

It is possible that the glider was the somewhat smaller Sugar Glider (Petaurus breviceps), but the pitch sounds too low, leading my biologist friend Simon Clulow to identify them as the calls of the Squirrel Glider. About a week before in the Watagan Mountains near Newcastle, I believe I snagged the Sugar Glider’s higher-pitched calls:

What fun it is to sleep out in the forest and know that possums are about and prone to hollering. In North America, “holler” is how mountain folks in the Southeast pronounce “hollow,” referring to a small forested valley with a creek. So “Possum Holler” actually means “Possum Hollow.” But here in Australia, possums really do “holler,” especially if you dare to sleep on the ground in the forest at night.

NOTE: If any of you Aussies beg to differ with my identifications, please let me know. Even the folks here at Newcastle University could be wrong.


  1. The Brushtail Possum’s growl sounds like it’s stuffed up and sick. The Sugar Glider sounds different than the Squirrel Glider not only because it’s bark is higher-pitched, it also calls faster.

  2. I guess I will have to disconnect from Music of Nature. Nothing you have sent since the middle of July has played on my device. All of the old stuff still works, but none of the new stuff. Ive had a couple of people look at it but no one can figure out what is wrong. The pictures are nice but the sound is what counts. Sorry to miss your Australian trip input.

  3. Lang, I just love the barking sounds of the Sugar Glider. Almost sounds like a dog. Getting my new dog tomorrow! Your sister, Jackie

  4. Excellent recordings! I’ve seen Sugar Gliders in captivity and I never knew they made such sounds, nor did I know they’re found in Australia. The Brushtail Possum growls sound kind of eerie. I can see how the growls shook you from sleep.

    Do you have any recordings or videos of frogs? I would really love to know.
