The following image is a Painted Honeyeater photographed at Stony Creek NR (the ACT version, near Urriara Crossing) in early December. It was hunting insects on the ground.
Taking a map from Birdata shows the normal range of the species to be more inland.
Adding to the importance of the Hoskinstown observations is the birds feeding young. While some of the Urriara birds were nesting it appears that nest was abandoned for some reason and the chicks (if hatched) didn't fledge
