DO YOU KNOW??

Most people think crows are black, and most are....but a number of species in the genus Corvus have extensive white in their plumage.... and are called
WHITE CROWS................ !!!!!!!!!!!!!

Even those species that normally are black may show patches of white on parts of their body..... or may be completely white......!!!!!!!!!!!!!!!!! Its called albinism, same as in humans, where there is problem in pigmentation....resulting in white colour ..... !!!!!!
