Is this normal color on Greenwing macaw's nape?

Any greenwing macaw experts out there?
Is light green nape feathers like this normal or a sign of liver disease or a deficiency? This is an older bird, kept indoors.
I never seen a greenwing with so much light green feather on the back and nape, I would really appreciate the info.
Thank you!!!

Is it possible that he/she is a hybrid? First thing that came to my mind when I looked at pictures.

It's hard to say without knowing the history. With the green carrying so high on the back it leads me to believe this parrot is actually a HYBRID, especially if it's older and has had a lot of molts. It's possible one parent was a true Greenwing and one parent was a hybrid greenwing or some sort, though the face is spot on for a Greenwing.

Of course to be sure you should take him to a certified avian vet who will be able to determine if there are deficiencies or any underlying health issues. I have never seen a deficiency cause the green to extend like that.

I agree with what the others say. Definitely looks to be some sort of hybrid, although you'd have to do a liver enzyme test or whatever to see if there's liver problems involved.

Besides the extra light green feathers on his nape, I don't see any other indicators of being hybrid, he is very much a normal average looking greenwing over 1300 grams at 24 yr old, was kept indoors, I don't know his past diet but the previous owner who owned him for 24 years seemed to care and like animals, but I have my doubts.


He will be tested by a avian vet but I wanted to reach out to you guys just for more info. Besides anything else the vet might find, I suspect he was fed a lot of colored pellets because he prefers them the most, or is used to them.

Anyone else have any experience or info on this greenwing's light green nape anomaly?

I can't answer your question, but I do agree with you that it is a green wing. He has far too many green wing features to be even 25% shamrock or other hybrid, in my opinion. Especially at 24 years old, when hybridization was not as common, let alone several generations of hybrids.

Thanks psy,
I'm thinking it might be diet and lack of UVB light and I hope he doesn't have any physiological internal damage from years of bad diet and lack of sunlight.
I'm adopting him, and will be getting him to a good avian vet for blood fecal and other tests.
He is very a sweet and gentle greenwing.
