Here's an explanation of leucism from Cornell Lab of Ornithology's "All About Birds" site:
"Leucism: Extra-pale plumage. Leucism is related to albinism, but in this case the normal pigmentation is diluted rather than lacking, resulting in birds whose plumage is lighter than normal, but not pure white. Plumage patterns, such as a mask or wingbars, often remain detectable." (www.birds.cornell.edu/AllAboutBirds/faq/master_folder/att...)
(Saxicoloides cambaiensis)
The Indian Robin (Saxicoloides fulicatus is a species of bird in the Muscicapidae family. It is widespread in the Indian Subcontinent, and ranges across Bangladesh, Bhutan, India, Nepal, Pakistan, and Sri Lanka. The males of northern populations have a brown back whose extent gradually reduces southwards with populations in the southern peninsula having an all black back. They are commonly found in open scrub areas and often seen running along the ground or perching on low thorny shrubs and rocks. Their long tails are held erect and their chestnut undertail covert and dark body make them easily distinguishable from the Pied Bushchat and the Oriental Magpie Robin.
The Indian Robin is sexually dimorphic in plumage with the main being mainly black with a white shoulder patch or stripe whose visible extent can vary with posture. The northern populations have the upper plumage brownish while the southern populations are black above. The males have chestnut undertail coverts and these are visible as the bird usually holds the 6–8 cm long tail raised upright. The females are brownish above, have no white shoulder stripe and are greyish below with the vent a paler shade of chestnut than the males. Birds of the northern populations are larger than those from southern India or Sri Lanka. Juvenile birds are much like females but the throat is mottled.
Several populations are named based on their plumage differences. The nominate subspecies refers to the population found across southern Peninsular India. Race leucopterus is found in Sri Lanka. Race cambaiensis of western India and erythrura (=erythrurus) of eastern India (south to around Sambalpur have the males with brown backs. The population intermedius includes forms between cambaiensis, erythrura and fulicata in central India and parts of the Deccan region. A race munda was named for a specimen from Punjab but is now considered synonymous with cambaiensis. Older classifications treat the population in southern India under the name ptymatura while considering the type locality as Sri Lanka although the type locality has subsequently been restricted to Pondicherry.
Local names recorded by Jerdon include Nalanchi (Telugu), Wannatikuruvi (Tamil, Washerman bird), Kalchuri (Hindi). The genus name indicates that it looks similar to Saxicola, the genus of the Pied Bushchat, a bird often found in similar habitats.
This bird is found in open stony, grassy and scrub forest habitats. They are mainly found in dry habitats and are mostly absent from the thicker forest regions and high rainfall areas. All populations are resident and non-migratory. The species is often found close to human habitation and will frequently perch on rooftops.

The species was introduced into the New York region but did not establish. A vagrant or escape has been noted from the Maldives.
Population densities of 193-240 individuals per square km have been estimated in the Pondicherry University campus. The ratio of males to females was about 1.5:1. Territory size for males is estimated at about 6650 m2. Males can be aggressive to others during the breeding season and will even attack reflections. Human activities such as felling and firewood removal in forests appear to benefit them.
Food
They feed mostly on insects but are known to take frogs and lizards especially when feeding young at the nest. Individuals may forage late in the evening to capture insects attracted to lights.
Breeding[edit source
The breeding season is December to September but varies according to region and usually begins with the first rains. Peak breeding in northern India is in June and is earlier in Southern India.In Sri Lanka it breeds in March to June and August to September. Males sing during this season and display by lowering and spreading their tail feathers and strutting around the female, displaying their sides and fluffing their undertail coverts. The songs of males have variants for inviting mates and for deterring other males. Males will drive away other males and patrol their territory by flying with slow wing-beats from perch to perch. They may sometimes peck at their reflections. An aggressive display involves fluffing up the feathers and holding the bill high.
Nests are built between rocks, in holes in walls or in a tree hollow. Nests are lined with animal hair and it has been noted that many nests have pieces of snake sloughs. The eggs are of regular oval form, but many are elongated and a few pointed. They have a fair amount of gloss. The ground-colour is white, often tinged with faint green or pink, and this is rather closely spotted, speckled, streaked, and mottled, with rich reddish or umber-brown and brownish yellow, with some underlying lavender. The markings are denser at the larger end of the egg, where they form an irregular cap. Some eggs are blotched with dark reddish brown at the large end. Eggs are about 0.76–0.84 inch (1.9–2.1 cm) long and 0.55–0.62 inch (1.4–1.6 cm) wide. Three to four eggs is the usual clutch. An abnormal clutch of seven has been noted although none of the eggs hatched at this nest. Only the female incubates. Eggs hatch in about 10–12 days. Chicks have black down. Both males and females feed the young, the males sometimes passing food to the female which in turn feeds the young.Nestlings may feign dead (thanatosis) when handled. Nestlings may be preyed on by the Rufous Treepie. The same nest site may be reused in subsequent years.
An old anecdotal record of these birds laying their eggs in the nests of Turdoides babblers has not been supported by later observers. Laboratory studies have demonstrated cyclic changes in the melanin pigmentation of the tissue surrounding the testes. The dark pigmentation is lost during the breeding season and regained later.
American Crow
Wagontown,
Chester County,
Pennsylvania
February 19, 2014
This is my second encounter with a mostly white American Crow in this area of Chester Co. I would guess it's the same crow with this pigment abnormality, but maybe there's another one out there in this area. This crow is darkest in the face, and then gradually loses its dark pigmentation as it reaches the tail, which appears pure white. Eye catching in flight, when you are not accustomed to seeing a white bird flying into the woods. I was able to snap off a few photos before it flushed off to a more distant branch. Hope to see this neat bird again someday.
A large male sunbathing and cooling itself with sand on Chrystalls Beach, Otago, New Zealand.
New Zealand sea lions are only found in New Zealand. They are one of the rarest species of sea lion in the world and arguably the most threatened because of their declining numbers and restricted breeding range.
Sea lions are found mainly on beaches in Otago and Southland areas and New Zealand’s Subantarctic Islands.
Under the New Zealand Threat Classification System the New Zealand sea lions is classed as Nationally Critical, the highest threat classification in New Zealand.
Formerly known as the Hooker's sea lion the species has a blunt nose and short whiskers.
There is a marked difference in appearance between adult males and females.
Mature males are brown to black in colour with well-developed manes reaching to the shoulders.
Females are lighter in colour, predominantly creamy grey with darker pigmentation around their flippers.
Adult females: length 1.6-2.0 m, weight 100-160 kg
Adult males: length 2.4-3.5 m, weight 250-400 kg.
Pups of both sexes are chocolate brown with paler areas around the head. Juvenile males can resemble adult females in colour and size.
Range
Archaeological evidence suggests that NZ sea lions used to be found along the entire length of the NZ coast from the north of the North Island down to Stewart Island and the subantarctic Islands. The finding of sea lion remains in excavations and historical records indicate that both Mäori and European settlers hunted sea lions.
Nowadays NZ sea lions breeding colonies are only found in the Auckland and Campbell Islands (North West Bay of Campbell Island). 79% of the species’ pups are born in three islands of the Auckland Islands (Dundas, Enderby and Figure of Eight). The Auckland Islands sea lion colonies are nevertheless a remnant of what used to be once before the island’s discovery in 1806. Soon after sea lions were exploited for their pelts for a period of 24 years until activities ceased due to the low numbers of animals remaining. It is evident that many New Zealand sea lions were killed during this time but it is unknown exactly how many due to poor and often non-existent record keeping. Occasional killings continued until the late 1880's when the animals were protected by law.
In 1993 a single female, born at the Auckland Islands, started to breed on the Otago peninsula. From 1993 to 2014, 63 pups have been born at the Otago peninsula with the original female's daughter, granddaughters and great-granddaughters now breeding there. Breeding is also occurring in small numbers on Stewart Island.
Haul-out sites are more widespread and extend to Macquarie Island in the south to Stewart Island and the islands of Foveaux Strait.
Sea lions favour sandy beaches as haul-out areas. On warm summer days they will flick sand over themselves to try to keep cool. Females with pups will often move well inland on islands using vegetation or forest for shelter.
Population
Recent population estimates set the total population at about 10,000 and declining. This makes the New Zealand sea lion the rarest sea lion species in the world. Apart from the Australian sea lion (whose population is estimated to be 10,000-15,000), all other sea lion species are in the hundreds of thousands!
The equivalent of albinism in animals, erythrism results from the inheritance of two recessive genes for the absence of pigmentation. Normally the katydid colour palette runs the gamut of greens, browns and yellows, colours which keep them camouflaged and aid in their survival. Although it has been hypothesized that pink coloration may increase survival rates amongst red vegetation it is much more likely that the genetic anomaly decreases fitness by increasing the insect's visibility to predators. Therefore it is likely that most individuals with this condition don't survive long and rarely make it to adulthood, which made this discovery all the more noteworthy. Found during a night hike in Vohimana reserve, Madagascar.

A large, freshly shed female Northern Water Snake found crossing a road in the early morning. I've never seen a Northern Water Snake with this amount of red pigmentation, I thought she was totally photo worthy.
This yearling Dusky Pigmy Rattlesnake lacks all red, orange, and yellow pigmentation, a genetic condition known as anerythrism. In the Apalachicola National Forest, about 10-20% of the individuals I encounter show this character. A normally colored pigmy rattlesnake of this age should have a red vertebral stripe and a bright yellow tail-tip.
It's simply amazing that the pigmentation of these ancient paintings has survived the erosion of time. It’s a special experience, and a real memento mori, to see these in person.
This blond fur seal has a condition called leucism that results in reduced pigmentation.
I photographed this rare seal at Shingle Cove, on Coronation Island in the South Orkneys.

Calopteryx virgo
The male usually has much more extensive pigmentation on the wings than other Calopteryx species in its range: in the south east of its range (the Balkans and Turkey) the wings are entirely metallic blue while in other areas, there are clear areas at the base and tip of the wing. Immature insects often have much paler, browner wings. They have metallic blue-green bodies and blue-green eyes.
The female has dark brown iridescent wings, a white patch near the tip of the wings (called a pseudopterostigma) and a metallic green body with a bronze tip of the abdomen
Females lay up to 300 eggs at a time on emergent or floating plants, often on water-crowfoot. Like the banded demoiselle, they often submerge to do so. The eggs hatch after around 14 days. Again, like the banded demoiselle, the larva is stick-like with long legs and develops over a period of two years in submerged vegetation, plant debris or roots. They usually overwinter in mud or slime.
The larvae of the beautiful demoiselle develop over 10 to 12 stages, each of which takes place between a molt. The body length is variable and highly dependent on environmental conditions. The final stage (F-0-stage) larvae are 3.5 to 4.6 millimeters and weigh about 4 milligrams, slightly below the banded demoiselle. Apart from the larvae of the demoiselles are difficult to distinguish from each other, the apparent differences lie mainly in the bristles and the severity of the tracheal gills on their abdomen. Compared to other damselflies demoiselles larvae fall immediately on the other hand, due to their much shorter mean gill lamella.
The body of the larvae shows only a relatively small adjustment to the fast-flowing waters of their habitat. The body is not flattened but very slim and turning around, the legs are long and have its end with strong claws, with which it can be stated in the vegetation. Because they reside within the water body, but mainly in the quieter areas, the danger of being swept with the flow, is relatively low. If this happens, they clearly its long body and legs stretched as far as possible to get in touch with the vegetation or the substrate to come.
The distribution of the beautiful demoiselle covers all of Europe with the exception of the southwestern Iberian Peninsula, the Balearic Islands and Iceland. In the north it extends to the Arctic polar sea, and thus much further north than that of the banded demoiselle. On the North African Mediterranean coast, its southern populations in Morocco and Algeria can be found.[1] The northern boundary in Asia following the 13-°C July isotherm, it is therefore not in the areas where the average temperature in summer below 13 °C falls, otherwise they are met with in temperate and cool regions in the entire continent with the exception of deserts and the mountains of. The eastern subspecies of C. v. japonica found on the Japanese islands is under debate as to whether it is a separate species. The beautiful demoiselle is mostly found in lowland locations. Regular findings come from areas up to a maximum height of 980 m above sea level. Occasionally they may be found up to 1,200 meters in altitude, such as in the Alps.
The blue-winged demoiselle lives mainly near small to medium sized streams and creeks. They prefer a relatively low water temperature and a moderate to fast flow. The water must not be nutrient rich (eutrophic). In the northern part of their range, such as in Norway and Finland, it is also found near medium-sized rivers or even larger streams. The waters are usually in the immediate vicinity of forests.
The larvae live in the streams mentioned before and are mainly dependent on the water plants. The larvae need the stems and leaves, especially in areas with stronger currents to hold on. Hence it is extremely rare to find them in barren locations, flat expiring banks, or areas with a smooth stone floor. They also live in small natural lakes or ponds characteristic for limestones bedrock. They live in quieter areas between alluvial leaves or on exposed roots of the vegetation. They can be found on submerged plants such as waterweed (Elodea sp.), floods for water crowfoot (Ranunculus fluitans) or other plants,submerged from a few centimetres to several decimetres. Compared with the larvae of the banded demoiselle the larvae of the blue-wing demoiselle prefer quieter areas of the water, since slower flow causes a more effective absorption of oxygen under water. Only in very rare cases the larvae are present in stagnant water. The substrate of the river has only a very minor importance, because the larvae reside mainly in the vegetation. An important factor for the occurrence of blue-wing demoiselles is the oxygen in the water. The larvae is much more sensitive to oxygen deficiency than the larvae of the banded demoiselle, hence it needs a sufficient oxygen saturation of the water. Waters with high levels of sediment and sludge, which is consumed by bacterial decomposition of oxygen are, accordingly not as a habitat for the larvae. This sensitivity qualifies it in water chemistry as a bioindicator for the assessment of water quality. Thus they will be an indication of value in the saprobic assigned of 1.9, which represents a low to moderately polluted waters type (β-mesosaprob) and a water quality class from I to II does. Another key factor for the occurrence of the larvae of the blue-wing demoiselle is the temperature of the water. This species prefers unlike the banded demoiselle, mainly the cooler and shadier areas of the water. The optimal temperature is a summer average 13 to 18 °C. At temperatures above 22 °C were often injuries of larvae observed and also a reduced hatch ability of eggs. The main reason is the oxygen content under higher temperatures. Individual populations may get used to permanently higher temperatures.
The habitat that the adults occupy, corresponds to the nearby larval habitat. Unlike the adults of the banded demoiselle you meet those of the beautiful demoiselle but also in forest clearings, but very rarely on the banks of larger ponds. As resting places, the animals need trees and shrubs, often resting on high herbaceous plants such as the large nettle ( Urtica Dioica ). The breeding habitats are similar to the Larval habitat, these are cool, shady water-courses largely with a more or less strong current and near-natural vegetation and bank structure. This is mostly meadow and pasture streams in the area, they rarely pass through the forest. A distinct riparian vegetation also plays a role as a windbreak. Due to their broad wings the beautiful demoiselle can be blown away by the wind more easily than other species of dragonflies.
Males are territorial, perching in bankside plants and trees. They chase passing insects, often returning to the same perch. Males can stray well away from water, females live away from water unless egg-laying or seeking a mate.
As with the banded demoiselle is also in the blue wing-demoiselle a pronounced territorial behavior of sexually mature males. These days occupy territories that they defend against other males. The defense consists mostly in threatening gestures. For this they spread their wings and put them on display so clearly visible, there is also Drohflügen and in rare cases to air combat between rival males. Optimal areas correspond to the optimal nesting places for the females and are characterized by a normally increased flow and a suitable oviposition substrate in the potential breeding sites from. The size of the spots and their distance apart is the density of the population dependent as well as the occurrences of the water and may be between several meters and a few decimetres. Males who do not occupy spots can keep themselves in the vegetation on the shore and try to mate with fly to females or to fill vacant spots. Especially when only a few males are present, the territorial defense is very aggressive, with a higher number of competing male aggression but decreases significantly. The males sit in their areas mostly in exposed places in the vegetation, which extends over the water, sometimes on vegetation or rocks cushions amid the waters. This seat is waiting at the same time the center of the district they do their gaze primarily on the aquatic center and will show a behavior that is referred to as "wingclapping" and in which the wings beat quickly down and slowly lifted. It is believed that it is mainly used for communication, it also supports the ventilation in the thorax and accordingly probably also plays a role in thermoregulation of the animals

A visit to the Butterflies Live! exhibit at the Lewis Ginter Botanical Garden last summer exposed us to several butterflies we had not seen before. A major reason for going was to take our granddaughter, Isabella, then 6; she loves butterflies. We enjoyed seeing them, as well. Materials were available at the exhibit to help identify the various butterflies, and I found more information on line through Google searches, trying to learn what we had seen. This Blue Morpho is one of many species of Morpho butterflies; the lower surfaces of the wings (below) are very different from the upper surfaces seen above. The blue coloration is said to be be the result of iridescence rather than pigmentation, causing exact color to depend on the viewing angle. It was difficult to get a picture of the upper wing surfaces because the butterflies typically closed their wings promptly upon landing, and in flight they flitted rather erratically. Morpho butterflies are said to be found mainly in South America, but can also be found in Central America and Mexico.
Butterflies Live! returns to the Lewis Ginter Botanical Garden this year, May 24-October 13.

The white tiger or bleached tiger is a leucistic pigmentation variant of the Bengal tiger, and Siberian tiger, and hybrids between the two. It is reported in the wild from time to time in the Indian states of Madhya Pradesh, Assam, West Bengal, Bihar, and Odisha, the Sunderbans region, and especially in the former State of Rewa. It has the typical black stripes of a tiger but carries a white or near-white coat.
Leucistic birds have less pigmentation than normal, so they will appear white or pale, in varying degrees. This is not an albino since there is some pigmentation and the eyes are not pink.
Leucism is a general term for the phenotype resulting from defects in pigment cell differentiation and/or migration from the neural crest to skin, hair or feathers during development. This results in either the entire surface (if all pigment cells fail to develop) or patches of body surface (if only a subset are defective) having a lack of cells capable of making pigment.

Common Grackle (Quiscalus quiscula ? )

This bird has blue eyes and a small dark patch on its head. This morph is said to be leucistic because it displays some pigmentation. A very rare bird. Albinism manifests as pink eyes and no pigmentation in the plumage.
..."The plumage color of the males is produced from carotenoid pigments in the diet.[10] Coloration is produced from both red pigments and yellow carotenoid pigments.[11] Northern Cardinal males possess the ability to metabolize carotenoid pigments to create plumage pigmentation of a color different from the ingested pigment. When fed only yellow pigments, males become a pale red color, rather than a yellow.[11]..." (From Wikipedia)
Females choose males who are good at finding food and a bright red male is a sign of a healthy industrious bird. However, they can get red coloration without being healthy from a nutritionally poor honeysuckle plant thus misleading a female and possibly not producing the best and strongest offspring.

Note: A variety of fruits and berries is good for developing red coloration --such as dogwood berries (there are many dogwoods in my yard)
The blackest Toad I've seen. I saw this at the edge of a very peaty loch in South Ayrshire when surveying for water voles. Presumably its the peaty surroundings that have led to it's pigmentation. Interestingly I saw many juveniles that were the more usual brownish colour.
Detail of stem showing a purplish-red pigmentation with raised nodules - distinguishes this species from native (to Ontario) congener (H. maximum).
I know this is not a very good picture, but I just wanted to share this find. It's a leucistic American Robin. Actually it has partial leucism. Leucism is a reduction in pigmentation. Partial leucism shows up as white patches, as you can see here on the bird's face. You see it a lot on Rock Pigeons. Check for it the next time you see one (or dozens, which is more likely).
Thanks for all your comments and faves!

A white American Robin, or piebald Robin, had been sighted in Boulder, and I finally saw it several days ago. These are also called piebald or leucistic Robins--a condition caused by lack of proper development of pigment cells. Piebald and partially leucistic animals typically have patches of normal pigmentation mixed with patches of white. This Robin's head and parts of the wings and tail have normal pigmentation, but most of the body is white and parts of the wings are white.

Laguna Colorada
Laguna Colorada (Red Lagoon) is a shallow salt lake in the southwest of the altiplano of Bolivia, within Eduardo Avaroa Andean Fauna National Reserve
The lake contains borax islands, whose white color contrasts nicely with the reddish color of its waters, which is caused by red sediments and pigmentation of some algae.
James's Flamingos abound in the area. Also it is possible to find Andean and Chilean flamingos, but in a minor quantity.
Through a digital process of converting colour images to black and white while manipulating the colour channels, I have studied the skin through lifestyle of humans. Skin pigmentation, sun damage, diet choice are some of the factors that get picked up in this style of digital manipulation.
