reported based on acacia chew marks with curled incisions and V shaped gouges for sap/gum feeding. could be other species but presumed Kreffts based on location and size or markings
Hi @rhyshardy, This is absolutely 'textbook' sign of sap feeding gliders, better than I would have imagined possible (unless it was faked by some tool-wielding human, which seems a lot less likely than that it is the real thing). There are only two local gliders which would do it and the other one is restricted to the mountains, so it has to be Krefft's. But I'm always a little bit more wary of records based on photos of sign rather than animals, and this is a first for me with this species, so I am wondering about putting a camera up to confirm it. Maybe you could message me if you are willing to show me these signs.
rhyshardy and DonFletcher There have been lots of tool-wielding Yellow-tailed Black Cockatoos recently on Mt Majura.... these omnivorous cockatoos even felled small trees.
Hi @waltraud , I think this is a bit different to YTBC sign. But on inspection of the real thing, if it is YTBC, it should be possible to see borer sign in the wood inside the damaged area. Or if we do get photos of Krefft's it would be fairly conclusive, I think.
