Xanthoria elegans is commonly known as the elegant sunburst lichen. Like all lichens, it is formed by fungi associated with an alga. This species grows on rocks and is recognized by its bright orange or red pigmentation with a circular distribution. It was one of the first lichens to be used for the rock-face dating through lichenometry. Many Xanthoria species growing in areas with intense UV radiation contain more carotenoids than those grown in more shaded areas.( Moledo beach, Portugal)
Xanthoria elegans é vulgarmente conhecido como o líquen-solar-elegante. Como todos os líquens, ele é formado por um fungo associado a uma alga. Esta espécie desenvolve-se nas rochas e é reconhecida pela sua pigmentação vermelha ou laranja forte que se distribui em círculo. Foi um dos primeiros líquenes a ser usado para a datação de paredes rochosas através da liquenometria. Muitas espécies Xanthoria que crescem em áreas com radiação UV intensa contêm mais carotenóides do que as que se desenvolvem em áreas mais sombrias. (Praia de Moledo, Portugal)
Unsure if that indicates a different species or just a different iris pigmentation from the more common paler variety.
Giant hogweed (Heracleum mantegazzianum), is a tall, cow parsley-like plant with thick bristly stems that are often purple-blotched. It can reach a height of 3.5m (11.5ft) when the flat-topped flowers appear, and has a spread of about 1m (3.5ft). It is usually biennial, forming a rosette of jagged, lobed leaves in the first year, before sending up a flower spike in the second. After flowering the plant usually dies, but not before spreading its seeds.
It is a member of the parsley or carrot family, Apiaceae (Umbelliferae). Except for size, it closely resembles cow parsnip, Heracleum lanatum.
Although it makes an impressive plant, it is invasive and potentially harmful - chemicals in the sap can cause ‘photodermatitis’ or ‘photosensitivity’; the skin becomes very sensitive to sunlight and may suffer blistering, pigmentation and long-lasting scars.
Indigo bunting derives it's signature color by refraction and reflection of sunlight rather than pigmentation. Their feathers are actually the brown-black hue of the primaries shown here
I've been neglecting my garden colony of Katiannid springtails recently. I've looked from time to time, but only seen some immature instars. Today I had a more intensive search.
Interestingly, there were none of the "typical" Group 1 and Group 2 adults, just this one "dark" form and two of "pale" forms (see previous image). Abd.6 has some pigmentation, but is paler than abd.5.
[Part of a garden survey of the "novel" springtail Katiannidae Genus nov.1 sp. nov. that I'm doing with FransJanssens@www.collembola.org initially, to establish the size and differences between the various instars. As a result of the initial findings, Frans is speculating that there are two distinct groups:
Group 1 - where abd.6 in adults is pale, and
Group 2 - where abd.6 in adults is dark.

Alter Ego: Kisser Corpse
Name: Alexis Hamilton
Allegiance: Villain
Powers:
* Skin pigmentation can change from a dead appearance to normal after draining.
* Her lips can drain someone of their powers temporarily (making them pale) and severely fatigue her victims, giving them the appearance of being deceased.
* After draining her physical attributes are heightened as if she is fuelled by it.
Weapons: None
Key Weakness: She is ordinary until she drains therefore easy to be taken down.
Origin:
Alexis is a meta human who grew up on the outskirts of a religious city called, Atlas which is located South of Avalon City. She was feared by local citizens because of her appearance as a corpse, it wasn't until she became a teenager she discovered her powers of draining. To look ordinary she would seduce younger men and absorb their energy through a kiss, once she began to blend in with society she was mugged by a criminal on the way home. She defended herself against the mugger and finally found out her super physical attributes after draining, it was then that she realised how she could use those abilities for self gain and get back at the people who once shunned her from society going by the name, Kisser Corpse.
I saw this bird at the park yesterday and I was very intrigued, wasn't sure if it was a baby hawk or eagle, or some exotic pet, I searched google every which way I could, and nothing.
I went on fb and asked a Washington Birders group about this bird and everyone got excited and I got my introduction to Ferdinand, who is somewhat of a celebrity.
Ferdinand is a crow with a condition called "Leucism" Leucism (/ˈluːsɪzəm, -kɪz-/) is a term used to describe 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.
Here's a blog post about this awesome crow:
A member of the cardinal family, the Indigo Bunting (Passerina cyanea) is just about as vibrant a bird as they come. It is as though a stitch of the sky has fallen and flutters through our trees, seeking out ways to return. Fittingly, these beautiful birds prefer to sing from the very highest perches that they can find. They also share another thing in common with the sky: neither is ACTUALLY blue. Indigo bunting feathers have no blue pigmentation. Instead, their feathers refract shorter wavelengthed blue light in the same way that air particles scatter it. But if you hold up an indigo bunting feather and light it from behind, you'll see that it actually contains dark brown pigmentation!
“Surrealism is destructive, but it destroys only what it considers to be shackles limiting our vision.”
Salvador Dalí . Sometimes what we perceive as real is actually surreal, while what we see as surreal is actually real. A orange and red river runs past white islands of borax salt (sodium borate) in Laguna Colorada. The red and orange colours in the lake are from pigmentation in algae which grows in the borax rich water. The lake sits high (4278m or 14035ft) in the Bolivian Altiplano in the Andes.

I believe the blue one may be a true axanthic specimen! I originally thought it might just be in-shed, but the more I looked at it the more convinced I was that this snake was actually just missing yellow pigmentation in the skin. What an exciting find!

Collected from deep in a Louisiana swamp, the ivory reptiles were part of a clutch of seventeen infants recovered by workers from the Louisiana Land and Exploration Company while surveying the area in 1986 .Leucistic animals have rare genetic condition that reduces the colour pigmentation in their skin.
Out of the 5 million american alligator population there are thought to be only 12 leucistic gators with Gatorland Orlando holding the world's largest collection at 4.
Due to their condition, the alligators are housed in special enclosures to protect them from sunlight - and the unwanted attention of other males.

Tundra Swans (whistling Swans) Generally believed orange coloration is due to deposition of iron Oxides on the feathers, thought to take place when birds feed in the water containing the iron salts in solution, rather than feather pigmentation. * Fir Island, Wa.
The white tiger is a pigmentation variant of the Bengal tiger. These tigers are found 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. A white tiger has the black stripes typical of the Bengal tiger, but has a white or near-white coat.
The beautiful shot of a majestic white tiger, with blue eyes striding forward as he roared, was such an amazing sight. The perfect pattern of stripes on the tiger body was a vision treat!

Basking on a culvert above a small swamp on Cullenbenbong road in the Kanimbla Valley. Estimated length 70 cm, taken from the car window.
Male of female? Patrick Campbell (Blue Mountains bushman) will know.
Trouble is, I have never seen a water dragon with this overall even colouration.
I'm seeing the distinctively deep angular head and nuchal crest of spinose scales that joins the vertebral crest extending down the length of its body to the tail.
The enlarged spinose scales present across the lateral surface, unevenly distributed amongst regular keeled scales.
The jowls are large and tympanum is exposed and of almost equal size of the eye.
The dorsal ridge and tail are laterally compressed and the limbs are strong and robust with particularly long toes on the hind legs.
It all says water dragon...

Here is another close encounter with a Manx Shearwater photographed in the Minch between Skye and Harris. They breed in enormous numbers at just a handful of sites in Britain, including the Isle of Rum which supports 40% of the British population. But they nest deep in burrows, and only return to their nests when it is very dark. So almost all of my sightings of Manx Shearwater have been chance sightings at sea. They usually keep well away from land during daylight so most of my sightings have been distant from coastal headlands. They are recognised by their long straight wings and short body, and by their shearing flight, which alternates flaps and long glides. Their plumage seems to flash black and white depending on whether you are seeing the black upperparts or the white underparts. Their legs and feet are supposed to be pink but I noticed that many had different coloured patches. On this individual its right foot is pink but its left one is largely black with pale patches. But it is rare you get a close enough view to study the foot pigmentation.
Showing the very elongated cells from the centre to near the base of the forewing which distinguish this species from any other British grasshopper. Males tend to lack the white wing-stripe, but have particularly strong red/orange/yellow pigmentation on the abdomen.

Early instar Black Swallowtail caterpillars are black and white, but soon acquire the light lime green that they retain through maturity...so I was surprised to find this mature instar lacking the green pigmentation at Weeks Bay Bog! I wondered if it was freshly molted and hadn't turned green yet...another mystery of nature!
Outside the Pinnawala Elephant Orphanage in Sri Lanka.
Taken hand held at a very close range walking backwards at the side of him, not cropped at all.
See the focal length how close I was.
You can see Three Mahouts are taking this Tusker to a River close by.
Very tamed Elephant, they said, but I took a risk getting few shots of him. I managed few front shots, but this is the image I prefer as you can see the whole body of him. Mature Sri Lankan elephants in particular display heavy pinkish pigmentation of the skin around the ears, face and trunk
These are the Souvenir shops along side of this street. The Two people walking at the back is our good friend "Colin Kirtley" (who visited Sri Lanka during our hols) and my wife Preeni who is wearing a Pink blouse and white jeans.
I really want to share this with you my Flickr friends who have not seen Asian Tuskers this close.
Thank you for your visits, faves and comments. Constructive criticism and suggestions are most welcome!

I have seen this very white wild horse several times, and just thought it was a white horse. After seeing this, I'm pretty sure it's an albino - look at that eye. There is no pigmentation! I'll be seeking this guy next time I'm out there, looking to get a close shot of that face.
Platalea ajaja: A juvenile bird at the Celery Fields, Sarasota, FL (04 March, 2022).
Breeding adults have more saturated pink/purple plumage on the wings and other distinctive pigmentation on the neck and face. The genus has species: this one is the only one with strong pink carotenoid pigments in its plumage. The other species are mostly white-plumaged.
Leucism is an abnormal condition of reduced pigmentation affecting various animals and birds, such as this House Finch, 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 feathers, hair, or skin...
This is my very first Leucistic bird and finally got to see it yesterday! It has been showing up in Eva's yard recently...the wind chill was in the teens and all the birds and I felt like icicles, but it was glorious to be out in the sun after a week of rain and overcast!

This bird showed up at Grindstone Creek in Hendrie Valley at the botanical gardens… apparently a melanistic form of Great Blue, producing abnormal plumage pigmentation.
Another from a series of shots I\'m doing for FransJanssens@www.collembola.org to establish the size and differences between the various instars of this Katiannid springtail. This one ticks another box!
It appears that as females of this species mature, some develop red pigmentation on the dorsal surface of the abdomen. This can make them difficult to distinguish from males. Others seem to develop less red pigmentation or none at all. Frans suggested that feeding and breeding instars may differ, with the breeding instars showing the red. This individual is a feeding instar (note green gut contents) but has a lot of red.
Note also the "white" areas on the head and lateral areas of the abdomen. I don\'t see this very often, but it is similar to a specimen that David (David_W_1971 ) photographed last year and posted a couple of days ago.
The only way to confidently identity females is to see the sub-anal appendage (SAA). This is difficult to see in photographs. I think though, that one may just be visible in the left-hand insert. Frans will confirm (or not!).
The black-legged kittiwake is a coastal bird of the arctic to subarctic regions of the world. It can be found all across the northern coasts of the Atlantic, from Canada to Greenland as well as on the Pacific side from Alaska to the coast of Siberia.
Black-legged kittiwakes' wintering range extends further south from the St-Lawrence to the southern coast of New Jersey as well as in China, the Sargasso sea and of the coast of west Africa. There are two subspecies of black-legged kittiwake. Rissa tridactyla tridactyla can be found on the Atlantic coast whereas Rissa tridactyla pollicaris is found on the Pacific coast.
The adult is 37–41 cm (15–16 in) in length with a wingspan of 91–105 cm (36–41 in) and a body mass of 305–525 g (10.8–18.5 oz). It has a white head and body, grey back, grey wings tipped solid black, black legs and a yellow bill. Occasional individuals have pinky-grey to reddish legs, inviting confusion with red-legged kittiwake.
The inside of their mouth is also a characteristic feature of the species due to its rich red colour. Such red pigmentation is due to carotenoids pigments and vitamin A which have to be acquired through their diet. Studies show that integument coloration is associated with male's reproductive success. Such hypothesis would explain the behavior of couples greeting each other by opening their mouth and flashing their bright mouth it to their partner while vocalizing.
As their Latin name suggests, they only possess three toes since their hind toe is either extremely reduced or completely absent.[7] The two subspecies being almost identical, R. tridactyla pollicaris is in general slightly larger than its counterpart R. tridactyle tridactyla. In winter, this species acquires a dark grey smudge behind the eye and a grey hind-neck collar. The bill also turns a dusky-olive color.[7]
Since kittiwakes winter at sea and rarely touch ground during this period, very little is known about their exact molting pattern.
The Kittiwake landed on the ship somewhere between Iceland and Greenland, before flying off again. It looked at me as though to ask to be left alone while it was resting.
A rock full of terns just off the Boulders Beach penguin colony in Simon's Town. The only ID I am sure of is the large tern in the middle with the yellow bill. This is a greater crested tern sometimes called a swift tern. For some reason it reminds me of Boris Johnson!
The others are either common or arctic terns that have migrated from the Northern hemisphere and developed their non-breeding (Southern hemisphere summer) plumage. This seems to include the loss of red pigmentation and hence my usual way of telling these birds apart (bill colour) when on the ground.
