House Sparrow with Isabellinism
The Difference Between Albinism, Leucism & Isabellinism
The different types of albinism have to do with the body’s inability to produce melanin, leading to white, gray, or cream-colored hair and skin. Leucism occurs when color pigments are produced in a lower amount than normal, and normal skin, fur, or feather patterns and textures remain. Isabellinism happens when normally dark-pigmented areas develop as a sort of washed-out grayish-yellow, and it’s supposedly named for an archduchess who refused to remove her underwear for three years. |
