I know this as Pushki and it's what is left over after it flowers and has gone to seed. There are still a couple of seeds on it still. This is a very common plant in Alaska and it's name is Heracleum maximum, also commonly known as cow parsnip. This is a plant to avoid since the sap of this plant on your skin is photosensitive and will create skin blistering on a sunny day. The resultant scars and pigmentation can last months or years.

The harsh truth is, most red-haired men look like blondes who've spoiled from lack of refrigeration. They look like brown-haired men who've been composted out behind the barn. Yet that same pigmentation that on a man can resemble leaf mold or junkyard rust, a woman wears like a tiara of rubies
A blue rose is a flower of the genus Rosa (family Rosaceae) that presents blue-to-violet pigmentation instead of the more common red, white, or yellow. Blue roses are often portrayed in literature and art as a symbol of love and prosperity, but which as a result of genetic limitations does not exist in nature.
Not the best photograph I have taken however we spotted this Hare occasionally during the winter months and assumed it was just in its winter coat however we noticed it again the other evening and getting a better view of it it does appear to be partially leucistic
Leucism in brown hares (Lepus europaeus) in the UK results in a pale or washed-out appearance, sometimes described as a "ghost" or "blue" hare. This condition occurs when there is a lack of melanin production, causing a reduction in pigmentation. Unlike albinism, leucism does not affect eye color, so leucistic hares will have normal brown or amber eyes.

Salares Boliviani : Laguna Colorada
La Laguna Colorada (Laguna Rossa) è un lago salato poco profondo nel SudOvest dell'Altipiano boliviano all'interno della Riserva Nazionale di Fauna Andina "Eduardo Avaroa" e vicino al confine con il Cile
La presenza, all'interno del lago, di isole di borace dal colore candido crea un forte contrasto con il rosso/arancio (a seconda delle ore del giorno) delle acque dovuto a sedimenti rossi e alla pigmentazione di alcune alghe che attirano qui una numerosa colonia di fenicotteri andini.
Laguna Colorada (Red Lagoon) is a shallow salt lake in the southwest of the altiplano of Bolivia, within Eduardo Avaroa Andean Fauna National Reserve and close to the border with Chile. The lake contains borax islands, whose white color contrasts 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.

Ochre and Purple Sea Stars (both Pisaster ochraceus, just different pigmentation) cling to a rock face at low tide on Canada's west coast. I made this shot just before the wasting syndrome that decimated sea stars all along the coast; thankfully, there are signs that they're making a recovery. I hope to receive a report soon from friends who are camping there - just up the hill from where this photo was taken - this week.
I don't know why I decided to place the sea stars off-centre in this frame; I think it just felt right. The pano crop was an afterthought. Tripod, late afternoon light, Pacific Ocean to my back at low tide but my head was on a swivel. That tide comes in pretty fast when it turns.

This leucistic trumpeter swan first showed up more than a month ago and I've come across him again. This pigmentation problem resulted in a very colourful bill.

The city of Edmonton, Alberta has the largest Black-billed Magpie population of any city in the world, and the the largest occurrence of leucism within a population of Black-billed Magpies.
According to Wikipedia: Leucism is a wide variety of conditions that result in 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.
The ruffled feathers on this guy were caused by a sudden wind gust while I was photographinh it.

We live in a colorful world, filled with a wide assortment of pigmentation. From the flowers to the sky, the humans to the skyscrapers — every facet of life is painted with a variety of colors. Maybe this is by mistake. Maybe it’s on purpose. Either way, this fact is to our good fortune, because to exist in a monotonous world — a world lacking in diversity — sure wouldn’t be as beautiful or interesting...

Leuzismus (von altgr. λευκός leukós „weiß“) ist eine Defekt-Mutation bei Tieren, die dazu führt, dass das Fell weiß und die darunterliegende Haut rosa sind, da die Haut keine Melanozyten (farbstoffbildende Zellen) enthält. Im Gegensatz dazu sind beim Albinismus die Zellen zwar vorhanden, aber unfähig, den Farbstoff Melanin zu bilden. Die meisten Formen der Scheckung sind auf abgeschwächte Formen des Leuzismus zurückzuführen.

Leucism is a wide variety of conditions which result in the partial loss of pigmentation in an animal—which causes white, pale, or patchy coloration of the skin, hair, feathers, scales or cuticles, but not the eyes. It is occasionally spelled leukism.
'Leucism' is often used to describe the phenotype that results 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 that can make pigment.
Since all pigment cell-types differentiate from the same multipotent precursor cell-type, leucism can cause the reduction in all types of pigment. This is in contrast to albinism, for which leucism is often mistaken. Albinism results in the reduction of melanin production only, though the melanocyte (or melanophore) is still present. Thus in species that have other pigment cell-types, for example xanthophores, albinos are not entirely white, but instead display a pale yellow colour.
More common than a complete absence of pigment cells is localized or incomplete hypopigmentation, resulting in irregular patches of white on an animal that otherwise has normal colouring and patterning. This partial leucism is known as a "pied" or "piebald" effect; and the ratio of white to normal-coloured skin can vary considerably not only between generations, but between different offspring from the same parents, and even between members of the same litter.
The humpback whale (Megaptera novaeangliae) is a species of baleen whale. It is a rorqual (a member of the family Balaenopteridae) and is the only species in the genus Megaptera.
The adult humpback whale is generally 14–15 m (46–49 ft), though longer lengths of 16–17 m (52–56 ft) have been recorded. Females are usually 1–1.5 m (3 ft 3 in – 4 ft 11 in) longer than males.
The species can reach body masses of 40 metric tons (44 short tons). Calves are born at around 4.3 m (14 ft) long with a weight of 680 kg (1,500 lb).
The body is bulky with a thin rostrum and proportionally long flippers, each around one-third of its body length.[15][16] It has a short dorsal fin that varies from nearly non-existent to somewhat long and curved.
As a rorqual, the humpback has grooves between the tip of the lower jaw and the navel. They are relatively few in number in this species, ranging from 14–35. The mouth is lined with baleen plates, which number 270-400 for both sides.
Unique among large whales, humpbacks have bumps or tubercles on the head and front edge of the flippers; the tail fluke has a jagged trailing edge.
The tubercles on the head are 5–10 cm (2.0–3.9 in) thick at the base and poke up to 6.5 cm (2.6 in). They are mostly hollow in the center, often containing at least one fragile hair that erupts 1–3 cm (0.39–1.18 in) from the skin and is 0.1 mm (0.0039 in) thick. The tubercles develop early in the womb and may have a sensory function as they are rich in nerves.
The dorsal or upper-side of the animal is generally black; the ventral or underside has various levels of black and white coloration. Whales in the southern hemisphere tend to have more white pigmentation. The flippers can vary from all-white to white only on the undersurface.
The varying color patterns and scars on the tail flukes distinguish individual animals. The end of the genital slit of the female is marked by a round feature, known as the hemispherical lobe, which visually distinguishes males and females.

This Leucistic Great Horned Owl was amongst the branches so I couldn’t avoid the shadows, but I’m pleased I got to see him. Leucism is the partial loss of pigmentation causing white feathers but not in the eyes.

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 The males feature wings with a signature orange pigmentation, which is the origin of A. cardamines' common name. Wikipedia
Numbers of these "novel" Katiannids (I never know what to call them!) appearing in our Staffordshire garden at the moment. Quite a proportion are "pale" individuals with reduced numbers of pigment spots. This one has a concentration of spots towards the rear of the large abdomen. Haven't seen this before.
Could the levels of pigmentation be related to when they last moulted?
Together with Frans & Marina looking for springtails between heather bushes in Opglabbeek(Louwel). It's so much more enjoyable to do together than on your own ! :-)
Perhaps it didn't rain enough, because we found only Entomobrya sp. We're going to try again some other time.

Like other rorquals, the humpback has grooves between the tip of the lower jaw and the navel. The grooves are relatively few in number in this species, ranging from 14 to 35. The upper jaw is lined with baleen plates, which number 540–800 in total and are black in color.
The dorsal or upper side of the animal is generally black; the ventral or underside has various levels of black and white coloration. Whales in the southern hemisphere tend to have more white pigmentation. The flippers can vary from all-white to white only on the undersurface. Some individuals may be all white, notably Migaloo who is a true albino. The varying color patterns and scars on the tail flukes distinguish individual animals.[
The end of the genital slit of the female is marked by a round feature, known as the hemispherical lobe, which visually distinguishes males and females.
Unique among large whales, humpbacks have bumps or tubercles on the head and front edge of the flippers; the tail fluke has a jagged trailing edge. The tubercles on the head are 5–10 cm (2.0–3.9 in) thick at the base and protrude up to 6.5 cm (2.6 in).
They are mostly hollow in the center, often containing at least one fragile hair that erupts 1–3 cm (0.39–1.18 in) from the skin and is 0.1 mm (0.0039 in) thick. The tubercles develop early in gestation and may have a sensory function, as they are rich in nerves. Sensory nerve cells in the skin are adapted to withstand the high water pressure of diving.
In one study, a humpback whale brain measured 22.4 cm (8.8 in) long and 18 cm (7.1 in) wide at the tips of the temporal lobes, and weighed around 4.6 kg (10 lb). The humpback's brain has a complexity similar to that of the brains of smaller whales and dolphins.
The structure of the eye indicates that eyesight is relatively poor, being only able to see silhouettes over long distances and finer details relatively close. Computer models of the middle ear suggest that the humpback can hear at frequencies between 15 Hz and 3 kHz "when stimulated at the tympanic membrane", and between 200 Hz and 9 kHz "if stimulated at the thinner region of the tympanic bone adjacent to the tympanic membrane". These ranges are consistent with their vocalization ranges.
As in all cetaceans, the respiratory tract of the humpback whale is connected to the blowholes and not to the mouth, although the species appears to be able to unlock the epiglottis and larynx and move them towards the oral cavity, allowing humpbacks to blow bubbles from their mouths. The vocal folds of the humpback are more horizontally positioned than those of land mammals which allows them to produce underwater calls. These calls are amplified by a laryngeal sac.

I've never seen such a light colouring in a New Holland Honeyater.
Leucism is a condition that results in an overall reduced pigmentation in an animal’s plumage, skin, hair or scales. Unlike albinism, which is the complete absence of melanin, leucistic animals retain some pigment and can have normal eye coloration.

As in interesting WWW thing, one site I checked had good info on Leucism, together with a picture of an albino bird !!! So much for AI
Native to the Americas and befitting any royal Egyptian necklace or coffin, the golden tortoise beetle is a species of insect with a rounded, domed body.
This beetle has a unique ability to change the shade of its pigmentation from bright to dull gold using microscopic cavities in its cuticle.
When threatened, the beetle presses its body close to the leaf surface, then tucks its appendages underneath its body like a tortoise.
Golden tortoise beetles are herbivores, feeding on plants in the Convolvulaceae family.

Taken back in the spring of 2007, here's "Houdini" looking at me suspiciously, probably wondering what I'm holding in front of my face. Houdini was born the previous summer, about 9 months before this was taken. Although he looks albino, he's actually leucistic... a condition similar in appearance but with some pigmentation present... usually in the eyes. Albino creatures have a total lack of melanin resulting in very light pinkish eyes. Houdini, like a number of leucistic deer in the herd had normal eyes, fully pigmented.
Here's a photo of Houdini taken 6 years later:
api.flickr.com/photos/61377404@N08/10062491784/in/album-7...
Sadly, Houdini and three other bucks were taken by a poacher over a four week period in early 2014. He was apprehended and justice was served, just not as much as he deserved.
This photo was taken with my second digital camera, a Kodak DX6490 point & shoot that had a great zoom lens and was small enough to carry in a jacket pocket. It didn't have image stabilization but was super easy to use and many of the best deer pictures I took were with this camera. The zoom lens wasn't used so much to get closer, but more to allow precise framing.

The white tiger is a pigmentation variant of the Bengal tiger, which is reported in the wild from time to time in the Indian states of Assam, West Bengal and Bihar in the Sunderbans region and especially in the former State of Rewa. Such a tiger has the black stripes typical of the Bengal tiger, but carries a white or near-white coat.
African golden Arab, (Colotis aurigineus), veined gold or double-banded orange, is a butterfly of the family Pieridae.
This stunning butterfly ranges from the Horn of Africa south to at least Tanzania, Malawi, and Zambia. The wingspan is roughly 5 cm. This individual is curiously asymetrical in the intensity of the orange pigmentation in the wings.
