A statistically minded member of Richard Allen’s long-running banding project at Weddins has sent me the below. Richard holds an enormous store of info on seasonal movement at that site : -
For the avoidance of doubt, the pattern of trapping of white-eared honeyeaters at Weddins. Hard to know whether the observed autumn altitudinal migration (from the top of the hill to the bottom) is really a true altitudinal movement or just a habitat/foraging shift correlated to (but not caused by) change in elevation.

Where I live in Carwoola (about 780m elevation) is pretty similar to Bungendore (about 710m) and we have White-eared Honeyeaters year round. For the majority of Canberra - about 580m - this species migrates in, in Autumn and stays through Winter. The graph shows the aggregate number of birds of this species reported in the GBS each week over the 30 completed weeks of the GBS.

There was a white-eared honeyeater in my yard this afternoon (Bungendore). It appeared to be feeding, possibly on a huge lavender bush that we have.
I'm just wondering, would it be expected that the honeyeaters have migrated by now?
