Yes, this is one of those birds where the light-dark pattern
depends on lighting and the angle of view. Like an NH or White-cheeked Hon
though, and not unique by any means. Video will show the changing features
better. This snap from this morning taking advantage of its odd sleepiness,
dozing at noon, in full sun:

Subject: [canberrabirds] grey oval on a White-fronted Honeyeater
Thanks
for posting these. A curious thing is shown from Geoffrey's photos. The one on
the right shows the clear grey oval below the bird's eye. This was one of the
first things I noticed about its plumage pattern. The books vary in showing
this (and many other characters). However that grey spot seems to appear and
disappear as the viewing angle changes. I think that maybe the feather tips are
dark, but bases may be grey, so when seen along the feathers, the grey oval
really shows, otherwise it doesn't. Compare left and right photos. I wonder if
this is worth formally writing up.
