This shot is of a male & female white lion in a reserve in South Africa taken with D90 and 300-70mm lens with 2x converter. The head rubbing or nuzzling showin in this image is a sign of affection and greeting within lion prides and renews their family bonds.
White lions are incredibly rare and much paler than the more common and widely recognised tawney lion. Their fur ranges from very pale, almost white, blond to a dark blond and their eyes are green, blue or gold depending upon the light in which they are seen. As said white lions are very rare and almost non existant in the ‘true’ wild, but they are found in large nature reserves within South Africa, where they are stringently protected. The white/blond colouring is due to a gene passed down from their parents and is only found in lions in this part of the world. The gene is recessive so two tawney parents may produce a white lion cub as long as both are carriers. More commonly however one or both parents tend to be white themselves.
