[QUOTE="CAU, post: 1249030, member: 55324"] Are you sure the colour of the lores and eye doesn't fit Intermediate Egret? Compare to the picture I linked (the picture labeled as Little Egret looks a bit underexposed). AFAIK true albinos lack melanin completely. Birds do have other pigments than melanin, however, so albino birds aren't necessarily completely white. A white plumage may also be caused by other means than albinism, for example the bare parts may be normally coloured, but the feathers white, which would probably be called a special case of leucism. Generally speaking the terminology for colour deficient birds is not too well established. Don't know any details about xanthochroism. [/QUOTE]
