White Out

The oddities of the natural world have always sparked the human imagination. While melanistic animals have been the talk of the town for the past few years, no doubt due to the frequent sightings of black panthers in the forests of south India, we’re turning our eyes to the colourless.

A flash of ivory. A ghostly apparition. Spotting an albino or leucistic animal in the wild is a rare wonder. These two conditions that render animals pale, arise from complete or partial lack of pigments in the body. In the former, the absent pigment is melanin, in the latter, it is a combination of missing pigments that characterise the condition.

While leucistic and albino animals are certainly appealing to the eye, they are also at an evolutionary disadvantage, and the majority of such animals may never survive to adulthood. In prey animals, their stark appearance makes them an easy target, while in predators, the condition robs them of the element of surprise. The distinct red or pink eyes of albino animals come with another drawback, the lack of melanin in the iris can effect the animal’s depth perception. The role of melanin goes beyond colour attribution; it also dissipates most of the absorbed ultraviolet radiation. Thus, animals lacking the pigment are prone to radiation-induced skin damage.

This is our ode to the alabaster survivors of the wild world.

Its ‘normal’ counterparts enjoy superb camouflage, but without it, this leucistic Malabar giant squirrel foraging on a tree is conspicuous to predators that include raptors and leopards. Should it find a mate, the chances of nest survival also drop due to its very obvious presence.

Its distinctive red eyes and pearly appearance, place this wolf snake firmly on the side of complete albinism. A very rare sight, as in snakes, leucism and partial albinism are more common. Such an animal rarely reaches maturity. If not hunted, UV exposure while basking will do it in.

Strength in unity! The cooperation of herd members and good parental care along with the absence of large predators is what probably gave this female albino blackbuck the chance to reach maturity. However, in this grassland habitat, constant exposure to UV radiation from the sun remains a concern.

Without its black and grey markings, this albino palm civet could be mistaken for a tiny spirit bear! This species is either crepuscular or nocturnal, which must make staying discreet exceedingly difficult for this ivory individual.

The loud green hues that are so typical of parakeets are completely missing from this Rose-ringed Parakeet. In the bird world where colours are near-always important to mating success, one wonders how this one will fare.

The flashy hues that are so typical of kingfishers are completely missing from this White-throated Kingfisher. In the bird world where colours are near-always important to mating success, one wonders how this one will fare.

Waders, like these Godwits, sport drab colours to blend into the mudflats on which they feed. This leucistic Godwit paints a pretty picture, standing out from its feathered kin. For a bird of prey, say a harrier, it unfortunately becomes an easy target.

Native to the Indian subcontinent, southern China and Southeast Asia, the sambar’s shaggy coat can vary from yellowish-brown to dark grey. Here a young albino stands out against the verdant green forest of the Bandipur Tiger Reserve.
