As I posted on the first thread;
I would take this bird to the vet and have them looked at.
It's unusual to have such bald areas without a reason - sometimes rubbing the cage, or a small injury etc can cause small bald patches as well as disease.
To add to this, I have never seen bald patches anywhere on my birds during a normal moult, even the first moult. Never bald patches around the eyes. Only when my birds had injuries they have had bald patches, or minor brood patches on one of my hens.
Some species of parrots can get little bald patches during moults, but from my experience with my own 7 roseicollis lovebirds, my uncles 14 roseicollis lovebirds, my friends 34 roseicollis lovebirds and my neighbours roseicollis lovebirds, I have never seen such thing.
I am not trying to scare you. But if you haven´t seen an injury in that area, and if your bird is alone and no other birds around to pluck that areas, and your bird is not rubbing their face on something a lot, then I would definitely be heading to the vet for some testing. I´m not saying it doesn´t happen, but it certainly is not common.
