Thanks, In Canberra Gang-gangs spend a third of their foraging time eating Blue Gum nuts and flowers - there are four sub-species of which bicostata is by far he most commonly planted in the ACT - make up. I have collated Gang-gang sighting records and used then to analyse Gang-gang diet which you can read about at

@MichaelMulvaney fantastic! About 8 years ago I had 2 gang gangs feeding on my pistachio tree but didn’t think to record it. I’ve never seen it since, perhaps they were getting desperate that year!

Yes Pistachio is a common Autumn food item perhaps their absence has more to do with where you live
