This bandicoot was eating fungi that were growing hidden under wet fallen leaves near the footpath. After he moved away, I rolled some of the fungi out of the leaves with a stick so that I can take photos for identification. After taking photos, the bandicoot came back and ate them (photos no.4 & 5). The fungi is https://canberra.naturemapr.org/sightings/4570937
So now you are literally experienced in the harvesting of native truffles and also experienced in the feeding of captive bandicoots, @KumikoCallaway. Bandicoots, Bettongs, and Mountain Brush Tailed Possums are among species that keenly seek native truffles. But curiously, Common Brush Tailed Possums are not known to do so.
Thank you for additional interesting information, Don. Yes, it was a very precious moment when we could observe bandicoots finding and eating truffles.
