White peacocks or peafowls are unique and rare white leucistic birds and they also look very beautiful. They are often mistaken as albinos, while in reality they are leucistic. In fact many leucistic animals and birds are often mistaken as albinos. Interestingly, this condition is also described as "albinoid" which means leucistic. The similarity in words "albinoid" and albinos shouldn't misguide you since these are different conditions. Albinoid means leuicistic or have the condition of leucism while albino means the condition is albinism.
Being albino means there is a complete lack of pigmentation which is usually a congenital condition, while being leucistic or albinoid means there is a partial lack of pigmentation.
Blue Peacocks known as the Indian peafowls are one of the most popular birds admired by most of us for their beauty. The white colored peacocks are rare, but they too look stunning.
The white peacocks are white in color due to the lack of pigmentation in the skin and feathers, even though this is rare in the wild but more common among those kept in captivity due to selective breeding.
Many times white peacocks are mistaken for albinos, but for albinos there is a complete lack of the pigment melanin which also results in pink eyes. The white peacocks have beautiful blue eyes (and sometimes few colored feathers too) and so they can't be considered as albinos.
