Lorikeet losing head feathers
(Melbourne, Victoria, Australia)
Hi. My rainbow lorikeet (normal type) has lost 70% of his feather for about 8 months now. First I thought it was natural molting, but then after 5months since it started, it spread down to the neck. He doesn't eat as much as he used to be.
He is the elder brother of the two (we bought the two brothers from the same breeder), one day older. He used to be the dominant and has reduced in body size and no longer a dominant bird for the last 6 - 8 months.
We are counting each new feather that comes out, but the next day or two the feather disappears. Some time we caught the young brother bird plucking out the feathers from his brother's head. The bald head naturally looks dry, but is not scaly or dark grey. He is not as active and friendly as he used to be. He doesn't talk much. He plays with his brother a bit, but not as much as when he was younger.
Is my bird sick? I note that he has becoming bity (biting a lot) lately and running away from us when we want to catch him. However if we stand still, then he will climb on and stay on our shoulders, but just doesn't want to be held (can't catch him easily like before). Could someone please help us advising whether our bird is sick, what is causing it and what could we do. Much appreciated. Thanks. Jenny
