  Birds in Backyards again has a very useful web page on this species at:
Actually this morning when out in more coastal heath I observed a group of 8 to 10 New Holland Honeyeaters landing and fluttering on the dead flower stalks of Grass Trees and initially  I thought they were White-cheeked Honeyeaters but when I checked with binoculars it correct identification resulted. With the naked eye and both species often very active error in identification is easily made.Here are the head images to illustrate the differences. Here is a comparison of the head of the New Holland Honeyeater and also that of the White-cheeked Honeyeater:

Note eye colour and distribution of white feathers on head compared to the following image.


White-cheeked Honeyeater (Phylidonyris niger)

Here the brown eye colour and white cheek are diagnostic. Obvious here but no so easy with the naked eye or from a distance.
