The brown anole (Anolis sagrei), also called the Bahamian Anole, is a lizard native to Cuba and the Bahamas. It has been widely introduced elsewhere, and is now found in Florida and as far north as Southern Georgia, Texas, Taiwan, Hawaii, and other Caribbean islands. In its introduced range it reaches exceptionally high population densities, is capable of expanding its range at an exponential rate, and both out competes and consumes many species of native lizards.
The brown anole is a slender lizard reaching about 18 cm in length. This anole has the ability to change coloration to match its surroundings. They can change pigmentation from brown, light tan, green, rust, to black. Males and females differ somewhat in coloration: males have a dark stripe down their backs, females a light stripe. The mature males weigh about twice that of females. As in other anoles, the male has a brightly colored throat fan, called a dewlap, which is yellow or reddish-orange. They are territorial and the dewlap is used in territorial displays. Anoles have expanded toe pads that allow them to cling to smooth surfaces.
Unlike the green anole which prefers foliage, the brown anole is found often on the ground. They are athletic creatures that run fast, and jump many times their length. They can also climb straight up almost any surface at blinding speed. The brown anole gets used to humans and can be studied at close range.
The brown anole feeds on insects such as crickets, grasshoppers, roaches, spiders, mealworms, and waxworms. It may also eat other lizards, such as the green anole, and lizard eggs. They will also usually eat their molted skin.

Photographed at Hakalau Forest NWR--Pua Akala Tract. This species is one of about 26 damselflies endemic to the Hawaiian Islands. Most are red, as is this species.
In species that are red, often both male and female are so, and these species are typically associated with locations that receive high solar radiation.The function of the red pigmentation appears to be as an antioxidant, which could provide protection from UV damage.
The Beautiful Hawaiian Dragonfly inhabits small pools and is one of the few native species that has benefitted from pigs, which create said habitat.

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.
Corvus corax Linnaeus, 1758 - northern raven (photo by Mary Ellen St. John).
Jays, crows, and ravens (Family Corvidae) have the largest body sizes of any passerine bird group in the world. Corvid passerine birds are omnivorous, aggressive, usually gregarious, have harsh calls, powerful beaks, and limited to no sexual dimorphism. These birds typically have bristles covering the nostrils along the upper proximal portions of the beak.
This is a northern raven. Ravens are much bigger than crows, up to 26 inches long. These intelligent birds feed on insects, mice & rats, & may take young birds & weak or injured animals. They have learned to hang around where humans congregate, collecting food scraps. They are commonly seen in the parks of western America. The metallic-lustered colors seen in the feathers of this northern raven are due to diffraction of light rather than pigmentation.
The northern raven occupies a variety of habitats in much of North America, Eurasia, and northern Africa.
Classification: Animalia, Chordata, Vertebrata, Aves, Passeriformes, Corvidae

Birds are small to large, warm-blooded, egg-laying, feathered, bipedal vertebrates capable of powered flight (although some are secondarily flightless). Many scientists characterize birds as dinosaurs, but this is consequence of the physical structure of evolutionary diagrams. Birds aren’t dinosaurs. They’re birds. The logic & rationale that some use to justify statements such as “birds are dinosaurs” is the same logic & rationale that results in saying “vertebrates are echinoderms”. Well, no one says the latter. No one should say the former, either.
However, birds are evolutionarily derived from theropod dinosaurs. Birds first appeared in the Triassic or Jurassic, depending on which avian paleontologist you ask. They inhabit a wide variety of terrestrial and surface marine environments, and exhibit considerable variation in behaviors and diets.
My photo meets the goals of this project because it displays bountiful color. It also portrays two colors who compliment each other very beautifully and two of the primary colors. I created this work by going to the park in my neighborhood and snapping pictures of items with interesting color. This car caught my eye with its beautiful cobalt blue pigmentation. My greatest strength is how clear the car is and how powerful its color is. If i could change anything it would be all of the leaves on the ground because I feel like they are distracting and make the photo look unprofessional.
Chester Zoo's Spirit of the Jaguar exhibit is home to five magnificent Jaguars. Their rainforest and savannah-themed enclosures replicate the range of habitats occupied by Jaguars in the wild.
Providing the animals with such stimulating environments promotes natural behaviours like climbing, stalking and swimming - which they especially enjoy!
Jaguars’ coats are usually golden with an intricate pattern of black spots, ringed by dark rosettes. ‘Melanistic’ Jaguar, Pele, has an increased amount of dark pigmentation, making his fur black. If you look closely, you can still the typical rosette markings on Pele’s coat.
To further encourage their Jaguars to behave naturally, keepers provide a variety of environmental enrichment including scent trails, scatter feeds, climbing poles, and hiding food (such as chicken, rabbit, beef or fish) around their enclosures. Wild Jaguars are opportunistic hunters, preying on a wide variety of mammals, reptiles and fish.
Cattle-ranching now dominates much of the Jaguars savannah habitats, where they have adapted to prey on domestic cattle - unfortunately bringing them into direct conflict with farmers.
Chester Zoo’s Jaguar and People Conservation Programme works to address human-Jaguar conflict and we also provide grants each year to support various Jaguar conservation projects.

American Robin, Turdus migratorius
Loyds Corner, NJ
Chronic inflammation affecting the cornea will lead sometimes lead to hyperpigmentation. It is referred to as keratitis (inflammed cornea).
INSTANT LIBERATION contains a selection of plant nutrients and medicinal clays that activate the skin’s metabolism. Its thermo-dynamic effect raises the skin temperature and the clogged sebum can be eliminated through the pore.
This eliminates the need to squeeze the skin with the fingers to remove cysts and blackheads, which would stimulate the appearance of even more spots. Using the masque on a regular basis unifies the skin tone and results in clean and fine pores.
The synergic action of the natural ingredients protects the skin from free radicals, which cause premature aging and pigmentation spots.

Humpback Whales: Black & White

COOL FACTS:
•Males sing complex songs on wintering grounds in Hawaii that can last up to 20 minutes and be heard 20 miles (30 km) away!
•In the Pacific, humpbacks migrate seasonally from Alaska to Hawaii--they can complete the 3,000-mile (4,830 km) trip in as few as 36 days!
•Humpback whales are well known for their long pectoral fins, which can be up to 15 feet (4.6 m) in length. Their scientific name, Megaptera novaeangliae, means "big-winged New Englander" as the New England population was the one best known to Europeans. These long fins give them increased maneuverability; they can be used to slow down or even go backwards.
•Several hunting methods involve using air bubbles to herd, corral, or disorient fish. One highly complex variant, called "bubble netting" is unique to humpbacks. This technique is often performed in groups with defined roles for distracting, scaring, and herding before whales lunge at prey corralled near the surface.
•Their body coloration is primarily dark grey, but individuals have a variable amount of white on their pectoral fins and belly. This variation is so distinctive that the pigmentation pattern on the undersides of their "flukes" is used to identify individual whales, similar to a human fingerprint.
•Humpback whales are the favorite of whale watchers, as they frequently perform aerial displays, such as breaching (jumping out of the water), or slapping the surface with their pectoral fins, tails, or heads.
•Humpback whales travel great distances during their seasonal migration, the farthest migration of any mammal. The longest recorded migration was 5,160 miles (8,300 km); seven animals, including a calf, completed this trek from Costa Rica to Antarctica.
•Also on wintering grounds, males sing complex songs that can last up to 20 minutes and be heard 20 miles (30 km) away. A male may sing for hours, repeating the song several times. All males in a population sing the same song, but that song continually evolves over time. Humpback whale singing has been studied for decades, but scientists still understand very little about its function.

Above this lion are horse-shoe like motifs. You can see they are very ancient because of their dark pigmentation. The pigmentation occurred when the climate was humid, and dust of manganese and oxide was blown onto the rock surfaces. That happened many thousands of years ago. It shows this site was significant for thousands of years, probably for different reasons. The pitting is typical, and may have been from some use the drawings were put. The exaggerated eyes of the lions were added later, often crudely.
In order to delay this location's inevitable destruction, I will tell you it's in Libya, but no more.

The Jackdaw (Corvus monedula), sometimes known as the Eurasian Jackdaw, European Jackdaw, Western Jackdaw, or formerly simply the daw, is a dark-plumaged passerine bird in the crow family. It is found across Europe, western Asia and North Africa, and four subspecies are recognised. At 34–39 cm in length, it is one of the smallest species in Corvus, the genus of crows and ravens. It is a black-plumaged bird with grey nape and distinctive white irises. It is an omnivorous and opportunistic feeder, and eats a wide variety of plant material and invertebrates, as well as food waste from urban areas. The Jackdaw has benefited from clearing of forested areas and is found in farmland and urban areas, as well as open wooded areas and coastal cliffs. (wikipedia)
This is bird has a pigment aberration, probably resulting from a dietary deficiency or due to a component of its diet. There were a couple of other Jackdaws with similar yet less obvious gold/brown pigmentation to the primaries and tail feathers. A crazy looking bird. Taken in Bray Harbour, Co. Wicklow.

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.
Individual from Andhra Pradesh, showing features of intermedius
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.

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.
