Xanthochromism (also called xanthochroism or xanthism), from the Greek xanthos (ξανθός) "yellow" and chroma (χρὣμα) "color", is an unusually yellow pigmentation in an animal. It is often associated with the lack of usual red pigmentation and its replacement with yellow. The cause is usually genetic but may also be related to the animal's diet.[citation needed] The opposite of xanthochromism, a deficiency in or complete absence of yellow pigment, is known as axanthism.

Birds

[edit]

Birds exhibiting genetic xanthochromism, especially deliberately bred mutations of several species of parrot in aviculture, are termed "lutinos". Wild birds in which xanthochromism has been recorded include yellow wagtail, wood warbler, Cape May warbler,[1] rose-breasted grosbeak, evening grosbeak,[2] red-bellied woodpecker, scarlet tanager, northern cardinal, great spotted woodpecker, common tailorbird, crimson-breasted shrike, kākāriki and kea. A Cornell University survey of unusual-looking birds visiting feeders reported that 4% of such birds were described as xanthochromistic (compared with 76% albinistic).[3]

Fish

[edit]

Xanthochromism is widely documented in fish, with the cases documented in:

Xanthic goldfish (sometimes defined as being amelanotic,[15][16] though are considered distinct from albinistic goldfish[17]) are commonly used to study the development of pigmentation as they possess only two types of pigment cells: xanthopores and iridophores.[18]
