A leucistic lapwing

Albinism - reduction in the melanin content (black colouration) causing whiteness - is a well-known condition in many animals. However, leucism - a reduction in all types of pigments, not just melanin - is probably more widespread and often confused to be albinism. Here, a Red-wattled lapwing, normally textured brown-grey on the wings (see previous post), displays leucism. The black on the neck and face, and on the flight feathers, are normal - this is not a condition of albinism for sure!
