White magpie chics.

Ornithologist Alv Ottar Folkestad, says that the white color is due to what is called leukism, ie a congenital condition in animals that leads to reduced pigmentation. The animal thus becomes lighter and can often be partially or completely white.

- Before it was called albino, but then the bird usually has a total lack of dye, but in most cases now we see that there is pigmentation on the beak and on the legs.
