Golden jewels.. ( lutino macaw ) Mutations of the blue and yellow macaw.. ( sex-linked recessive ) by my friend Torch lutino macaw.. Lutino is a term used to describe birds that exhibit a yellow pigmentation known as xanthochromism. Birds exhibiting genetic xanthochromism, especially deliberately bred mutations of several species of parrot in aviculture, are termed "lutinos". Lutino is of the Blue & Gold Macaw species. These are extremely rare, particularly in Australia. Instead of having a black beak, claws and facial features, and the usual vibrant blue and gold feathers of a standard Blue & Gold Macaw, our Lutino has bright yellow-orange feathers and white features - including a white beak, tongue, legs and claws. It's eyes are a pinkish grey instead of black.
