Are zebras black with white stripes or white with black stripes?
Seriously though, they used to be believed to be white with black stripes because the underbelly is white. They are now however believed to be black with white stripes. Melanocyte skin cells "activate" the dark hair pigmentation. In the case of the white stripes this development is inhibited. Therefore the colour of the hair/fur is black and the white stripes are a lack of colouration.
The blackbuck, (Antilope cervicapra) also known as the Indian antelope, is an antelope commonly found in India. The blackbuck is the sole extant member of the genus Antilope. This shot was taken in Velavadar, Gujarat. My blog on Velavadar can be seen at jagadipsingh.blogspot.in
The white blackbuck here is either albino or leukistic. Albinism in Blackbucks is rare and caused by the lack of 'Melanin'. The animal looks fully white due to the lack of melanin in their skin. Wildlife experts say that the biggest problem with these Albinos is that they are singled out by predators and hunted. These are Albinos.
Leucism is a condition characterized by reduced pigmentation in animals and humans. Unlike albinism, it is caused by a reduction in all types of skin pigment, not just melanin.
The Black Glacier
An unpaved road climbs up to the Ventisquero Negro (Black Glacier), a reconstituted glacier full of sediment that gives it its namesake black pigmentation.
A new lake that is less than 100 years old at the bottom of the glacier has the same green hue as the Manso River and other bodies of water in the region.
Mount Tronador is pure ice at its peak, surrounded by hundred-meter cliffs that generate the rumbling avalanches and landslides.
The debris from the avalanches feed the lower lip of the glacier, giving it its dirty appearance.

I was in the blind when a small flock of American Robins flew in and started to graze on the lawn and also eat the berries on the cedar tree. This leucistic one was in the tree and then flew back into the woods. A little while later it came in for a drink. I got a few quick shots and off it went. It came back a couple days later and I haven't seen it since.
Leucism is a condition that results in the partial loss of pigmentation in an animal causing white, pale, or patchy coloration of the skin, hair, feathers, scales, or cuticles, but not the eyes. Bill's Backyard Bird Blind.
Leucism is defined as a condition in which there is partial loss of pigmentation in an animal resulting in white, pale, or patchy coloration of the skin, hair, feathers, scales or cuticle, but not the eyes. It differs from albinism in which there is no dark pigment at all, the animal appears pure white, and even the eyes appear red.
Leucisitic animals may have some dark pigments and the eyes are the normal color.
I found this young male in my backyard. Lake Wales, Polk County, Florida.
Have never seen him before.

Red peonies in a garden can command our attention from a distance. Planted in partial shade, the darkness of the deep red varieties intensifies in contrast to those grown in full sun. When the peony buds are developing and opening under cloudy skies, you will see darker pigmentation than when they develop and bloom in hot sun. That is why the vibrancy and hue of some peonies may vary slightly from one season to the next.
Darker red peonies come in single, double and Japanese style blossoms; some are accentuated with golden stamens peaking through their petals. Black Swan, Bob, Buckeye Belle, Charm, Chief Black Hawk, Old Faithful, Red Charm, Rubra Plena and Topeka Garnet are some of the deep reds that just shout out for attention.
The white tiger or bleached tiger is a pigmentation variant of the Bengal tiger, which is reported in the wild from time to time in the Indian states of Madhya Pradesh, Assam, West Bengal and Bihar in the Sunderbans region and especially in the former State of Rewa.They're not albinos. They're simply tigers that are born with white fur. White fur is a very rare genetic mutation. It occurs in the wild possibly in as few as 1 in 10,000 wild tiger births.
Epipactis palustris - var ochroleuca (Orchidaceae) 188 23
Epipactis palustris name (palustris) refers to its usual choice of a wet marshy habitat. This preference is reflected in the orchids unsurprising common name of the Marsh Helleborine.
This is a species with a huge distribution across temperate Europe and Asia from Britain and Scandinavia in the west to Siberia in the East. It can grow in dense colonies, particularly in the damp, alkaline conditions it prefers such as dune slacks and base rich fens. Epipactis palustris is not however restricted to calcareous soils and although usually in smaller numbers, seems perfectly capable of thriving not just in neutral conditions but also in moderately acid ones.
Unlike many of the members of the Epipactis genus, Epipactis palustris does not seek out shade and indeed will not flourish if surrounding vegetation gets too rank or high. Although its roots require an uninterrupted supply of moisture, the visible parts of the plant seek full sun and this accounts for its total suitability to life in the wet slacks of large dune systems. It is not however a deep rooted orchid and in fact has only a shallow root system which is well suited to vegetative reproduction in wet ground. These shallow roots also maintain the plants nutrient supply by staying clear of the deeper and poorly oxygenated permanent water level.
This is not a particularly variable species but forms with reduced dark pigmentation are common. Here, the red pigmentation is absent altogether, this variant being known as var ochroleuca.

Piebald is a genetic abnormality that results in a lack of pigmentation in animals. Both parents must carry the recessive gene to produce an offspring with Piebaldism.
Either way, this baby is awfully cute!
This little cutie got tired of mom cleaning her bottom to keep her scent free from predators. She had play and exploring on her mind and simply walked away from mom as if- I'm clean enough!
Before the blue hydrangea flowers fade they go through several tints ... here they are in their green state! So I put them together with one of my latest miniature vases from Yuta Segawa. The background bokeh is the hydrangea bush beyond the window...
Happy Bokeh Wednesday!
When I looked it up online I discovered ....."Hydrangea flowers can turn green in response to fewer hours of daylight. With less sunlight there is less energy for the flower heads to produce the blue, pink or white pigmentation in the blooms. This causes the hydrangea flowers to fade from their original color to green in late Summer"

Yesterday looked out my window and this little one was feeding with other birds. I'm not certain but believe it to be a Leucistic Sparrow. An abnormal condition of reduced pigmentation affecting various animals (such as birds, mammals, and reptiles) that is marked by overall pale color or patches of reduced coloring and is caused by a genetic mutation which inhibits melanin and other pigments from being deposited in their feathers.

The blue color of the blue-footed booby's webbed feet comes from carotenoid pigments obtained from its diet of fresh fish. Carotenoids act as antioxidants and stimulants for the blue-footed booby's immune function, suggesting that carotenoid-pigmentation is an indicator of an individual's immunological state. Blue feet also indicate the current health condition of a booby. Boobies that were experimentally food-deprived for forty-eight hours experienced a decrease in foot brightness due to a reduction in the amount of lipids and lipoproteins that are used to absorb and transport carotenoids. Thus, the feet are rapid and honest indicators of a booby's current level of nourishment.
As blue feet are signals that reliably indicate the immunological and health condition of a booby, coloration is favored through sexual selection.
Mara North Conservancy, Kenya
during the first game drive of this Kenya trip we saw a very special bird in a mixed bird party that moved around in an area with lots of bushes. We decided to follow them to possibly find and photograph this special bird.
After about 20 minutes of intensive searching we had a brief view and I managed this shot from about 12 m
I think it is a leucistic morph of the Purple Grenadier, the bird shown in my previous post.
Leucism means that an animal has a partial loss in pigmentation.

The white Tiger~
( clicked at Indira Gandhi National zoo in Vizag)
The white tiger or bleached tiger is a leucistic pigmentation variant of the Mainland tiger. It is reported in the wild from time to time in the Indian states of Madhya Pradesh, Assam, West Bengal, Bihar, Odisha, in the Sunderbans region and especially in the former State of Rewa.
There is only one tiger species and only two recognized subspecies in the world—the Continental (Panthera tigris tigris) and the Sunda (Panthera tigris sondaica). In fact, this white coat would be a hindrance in the wild, as it doesn’t provide a tiger with any camouflage, which greatly reduces their chance of survival.
Inbreeding all tigers, not just white tigers, is common in captive facilities and inbred animals suffer from a range of significant health problems. Common issues include spinal deformities, defective organs, and immune deficiencies. Instead of admiring the color of the tigers’ coats, we should be asking ourselves why these tigers are here in the first place, instead of in the wild.
Honestly this sweet little girl was a dream to photograph. She is a Red fox but leucistic, not albino. Blue eyes can be found in Leucistic foxes, though it is very rare.
A leucistic red fox is a result of a rare genetic condition causing a (partial) loss of pigmentation. Albino foxes lack melanin and have red or pink eyes, but a leucistic fox has normal eye colour though this little girl has bright blue eyes.

According to Wikipedia Gymnocalycium mihanovichii is a species of cactus from South America. The most popular cultivars are varied mutants which completely lack chlorophyll, exposing the red, orange, or yellow pigmentation. These mutant strains are often grafted onto the hylocereus cactus, and the combined plant is called a "Moon Cactus".
Moon cacti are commonly grown as houseplants and are also known as Ruby Ball, Red Cap, Red Hibotan, or Hibotan cacti.

Most woodland wildflowers are done blooming for the year but this delightful Indian pipe plant is still in fine flowering form! Most Indian pipe plants are pure white and give rise to the common name "ghost plant". This particular plant has some pretty pink pigmentation which was probably picked up from minerals in the surrounding soil. Indian pipe is a flowering plant just like a rose but it lacks chlorophyll and relies on help from nearby fungi for its fuel that the roots tap into.
One of the few species of diurnal owl, the great Snowy Owl (Bubo scandiacus) has evolved with little pigmentation in its feathers. This not only helps to camouflage these birds of prey, but also provides more space for air to be held within its feathers, keeping them warm. These beautiful birds are often spotted near airfields or farmland, perched on telephone poles, as these landscapes are similar to the tundras of the north and allow them to hunt in the ambushing style that they prefer.
I have photographed Red Squirrels, I have photographed Grey Squirrels, but I have never photographed a White Squirrel. I set out recently to try and achieve this.
“White” Grey Squirrels are very scarce in the UK but a huge area of woodland was rumoured to have one.
It took me a long time to track it down. This is no bird feeder raider and is very wary and camera shy ! You wouldn’t believe how elusive a pure white squirrel can be, but, once I managed to work out where it’s territory was, I enjoyed some success. It really knocks your eye out when first seen but it is a master of ghosting away into the abundant cover, and the search has to resume once more.
This Squirrel is not “albino” because it does not have pink eyes. It is actually “leucistic” - lacking pigmentation in the skin but with normal coloured eyes.
It is surviving very well because it’s eyesight is not affected by this condition.
It has been interesting to see this scarce animal and to watch it’s habits. I had no idea that a squirrel’s territory can be so small and how much time they spend resting and hiding away, inactive in their dreys.
Thank you for having a look at my photos. Comments or faves are very welcome and much appreciated.
The leucitic,or "white" Red Kite photographed at Gigrin farm, Rhayader. It's unusual colour is caused by a rare genetic mutation which prevents normal pigmentation of the feathers resulting in predominantly white or pale plumage.

This robin bird come to my feeder for couple days now he has a condition named "Leucism" is a condition in which there is partial loss of pigmentation in an animal resulting in white, pale, or patchy coloration of the skin, hair, feathers, scales or cuticle, but not the eyes. Also sorry for the poor quality in the picture my camera is staring to failing recently.
From Wikipedia, "Gymnocalycium mihanovichii, often called chin cactus, is a species of cactus from South America commonly grown as a houseplant. The most popular cultivars are varied mutants which completely lack chlorophyll, exposing the red, orange or yellow pigmentation. These cultivars are often called moon cactus. Since chlorophyll is necessary for photosynthesis, these mutations die as seedlings unless grafted onto another cactus with normal chlorophyll."
Such peanuts lovers they are constantly around any feeders in the fall making their presence known by the noisy calls. I love to observe them as they fly and grab the seeds or peanuts.
"Bird colouration is produced in a variety of ways, of which pigmentation is just one. The blue appearance of many blue birds is due to refraction – a light scattering phenomenon. The barb structure of Blue Jay feathers is such that, when light hits them, the blue light is refracted while the other wavelength of visible light are absorbed by the melanin, making them look blue.
If you come across a Blue Jay feather, try backlighting it. Without direct light, the blue is no longer reflected and the feather will look brown." - NatureCandada.ca
A blue Whiptail? I was stumped. So I contacted lizard expert and co-author of Lizards of the American Southwest, "The Lizard Guy" Larry Jones. he said the best he could tell, this is a Sonoran Spotted Whiptail (Aspidoscelis sonorae). Larry says: "that sometimes old individuals get lotsa blue pigmentation." He also says for those of you who are into taxa: (A. flagellicauda was subsumed into A. sonorae). All I know is this is the only blue whiptail I have ever seen 💙

This amphibian isn't just any ordinary frog. It has skin that’s so dark, it seems to absorb all light, giving it a mysterious, almost cosmic glow. The name “Galaxy Frog” isn’t just a cool nickname—it’s a nod to its spangled, starry appearance, with speckles and patches of lighter pigmentation that resemble a miniature galaxy across its jet-black body. It’s a perfect blend of nature’s mystery and pure celestial beauty!
If it looks like a duck and quacks like a duck but it needs batteries, you probably have the wrong paradigm.

Leucism is a partial loss of pigmentation, which can make the animal have white or patchily colored skin, hair, or feathers.
Anthocharis cardamines, the orange tip, is a butterfly in the family Pieridae, which contains 1100 species of butterfly. A. cardamines is mainly found throughout Europe and temperate Asia (Palearctic) The males feature wings with a signature orange pigmentation
(Milvus milvus) I was really thrilled to be able to photograph this incredibly agile wild leucistic red kite on a recent trip to Mid Wales. Apparently it is a youngster and started appearing at the farm around December time. There are only about 10 of these birds known in the world and three of them have been seen at Gigrin Farm! Leucism is an animal condition in which there is partial loss of pigmentation resulting in white, pale, or patchy coloration of feathers, skin or hair. It is not albinism as they lack the red/pink eyes of a true albino.

I like this Buck's eyes. They have different pigmentation than those of the others. I haven't got a name for him yet, and names are important. What would you name him?
