Never many problems identifying Yellow Honeyeaters (Lichenostomus flavus). They're just so, well, very yellow, noisy and busy. And, as with quite a few honeyeters, grey-eyed.
They seldom sit still, and prefer to forage away from in open sunlight. Had hopes for above picture, on tulip tree, but image too soft.
White-gaped Honeyeaters (Lichenostomus unicolor) share eye colour and much else with Yellows: side by side in bird lists, on same branch in one field guide, share habitat in north Queensland. Above bird kept returning to old Shining Flycatcher nest and eating bits of lining.
Bovine bonus: Cattle Egret and adopted family watch me seeking Double-barred Finches yesterday (post upcoming).
