In Australia, this bird is commonly known as the Olive-backed Sunbird around my area, but I understand that this group has since been split,according to DNA and plumage differences. My current understanding is that the cinnyris frenatus /Sahul Sunbird has the yellow above and below the eye, whilst the cinnyris jugulatus/ Garden Sunbird male has a brown head. I assumed incorrectly that all Australian sunbirds were called Olive-backed. I hope I've got it right now.
