We’ve written before about leucism in crows and ravens, which can cause lighter or abnormal coloring. This little crow, however, is an albino; the difference being that leucism is a loss of pigment, whereas albinism is a lack of it.

What do you think, he said,  is the most beautiful bird?
I do not know, I say, probably the swan?

It is the most beautiful bird, because it is more difficult than others. She will always stand out. Therefore, as a rule, every game becomes the object of attack. But it is much more important than any crows in flight. Imagine a flock where within flies only one white crow. One will not remember the whole flock!  In life, these birds do not seem to happen.
