Hi, I am John, I live on London and I have had Gizmo, a hawk-headed parrot since he was a baby, he is now 19 years old. The reason I joined the forum today is to ask whether anybody knows about parrots' nostrils' health. Gizmo injured himself last week, his left- hand side cere has been injured and he has been scratching that area a lot since. Now the whole membrane on that side is gone... The area looks a bit wet every now and then and he sneezes a bit. He seems ok, but I am really worried as on the left-hand side the nostril is exposed and there is a large hole. I am seeing the avian expert on Monday but was wondering if anybody knows more about membrane/cere, can this be serious? Will it grow again? Anything would help... I can post an image if that would help. I would be grateful for any advice, and thanks to all for reading in advance. Many thanks, John
