Razorbill - Alca Torda
The razorbill or lesser auk (Alca torda) is a colonial seabird in the monotypic genus Alca of the family Alcidae, the auks. It is the closest living relative of the extinct great auk (Pinguinis impennis). Wild populations live in the subarctic waters of the Atlantic Ocean.
Razorbills are primarily black with a white underside. The male and female are identical in plumage; however, males are generally larger than females. This agile bird, which is capable of both flight and diving, has a predominantly aquatic lifestyle and only comes to land in order to breed. It is monogamous, choosing one partner for life. Females lay one egg per year. Razorbills nest along coastal cliffs in enclosed or slightly exposed crevices. The parents spend equal amounts of time incubating, and once the chick has hatched, they take turns foraging for their young.
In 1918, the razorbill was protected in the United States by the Migratory Bird Treaty Act. Presently, the major threat for the population is the destruction of breeding sites.
Their mating system is female-enforced monogamy; the razorbill chooses one partner for life. It nests in open or hidden crevices among cliffs and boulders. It is a colonial breeder and only comes to land to breed. The annual survival rate of the razorbill is between 89-95%. Though the razorbill's average lifespan is roughly 13 years, a bird ringed in the UK in 1967 survived for at least 41 years—a record for the species.
Razorbills dive deep into the sea using their wings and their streamlined bodies to propel themselves toward their prey. While diving, they rarely stay in groups, but rather spread out to feed. The majority of their feeding occurs at a depth of 25 m (82 ft) but they have the ability to dive up to 120 m (390 ft) below the surface. During a single dive an individual can capture and swallow many schooling fish, depending on their size. Razorbills spend approximately 44% of their time foraging at sea.
When feeding their young, they generally deliver small loads. Adults will mainly feed only one fish to their chick with high feeding deliveries at dawn and decreased feeding 4 hours before dark. Females will generally feed their chicks more frequently than males. They may well fly more than 100 km (62 mi) out to sea to feed when during egg incubation, but when provisioning the young, they forage closer to the nesting grounds, some 12 km (7.5 mi) away, and often in shallower water.

Bush Dogs are so rare that they were thought to be extinct when first discovered through fossils. The Bush Dog is the only living species in the genus Speothos, and genetic evidence suggests that its closest living relative is the Maned Wolf of central South America. In spite of its extensive range across Central and South America, the Bush Dog is very rare in most areas except in Suriname, Guyana and Peru.
The Bush Dog was first identified by Peter Wilhelm Lund from fossils in Brazilian caves and was believed to be extinct. Lund was a Danish paleontologist, zoologist, archeologist who spent most of his life working and living in Brazil. He is considered the father of Brazilian paleontology as well as archeology.
An old volcano on the Peninsula. Maori name Hereweka, also called Harbour Cone. Our whole harbour is a volcano crater, extinct since 10 million years ago. It was active for about 6 million years before that. Thinking of people in the Canary Islands about 100 km west of Morocco just now.
Thanks very much for comments.

Extinct in the UK by the end of the 19th century due to habitat loss and persecution, occasional nesting pairs returned to eastern England during the 1970’s. Numbers have increased steadily since then . Many birds now overwinter and quite large roosts can be seen in some areas, especially in eastern England. The recent roost counts locally have found as many as 20 birds roosting in one spot . It is estimated that 350 to 390 pairs bred in the UK last year
Yes...Extinct in the Wild. Simandoa Cave Roach, a harmless insect that lived a symbiotic relationship with bats. Miners tore down the cave - and the only specimens we have left are captive bred.
Some of the moai found around the island have these large, red pieces on their heads. Despite what they look like, these aren’t hats, but are rather the hair styles (top knots) of those particular people represented by the statues.
Called ‘pukaos’, these large rocks were carved at the Puna Pau quarry out of red scoria, and are different to the rest of the stone you can find around the island.
A trip to Puna Pau allowed me to look into the quarry, as well as saw a number of pukao that never made it to their final destination.
The red slope in the foreground marks a volcano (it's extinct. The iight-green moss in front of it covers an old lava field.

Eguisheil est l’un des plus beaux villages de d’Alsace ( il a été élu plus beau village de France en 2013 ) avec ses maisons à colombages , son tour de ville le long des remparts et son château des comtes sur la place centrale .
Le site semble avoir été occupé dès le paléolithique, puis par les romains. C’est de cette époque que date la première culture de la vigne.
Le village commence son développement après la construction du premier château d’Eguisheim au VIIIème siècle par le comte Eberhardt, petit fils du troisième Duc d’Alsace. Il est ainsi l’ancêtre du Pape Léon IX et le neveu de Sainte-Odile, patronne de l’Alsace. A l’extinction de la lignée des Comtes, au début du XIIIème siècle, la ville est léguée à l’évêché de Strasbourg. Au cours de ce siècle Eguisheim est élevée au rang de ville, fortifiée et rattachée au Haut-Mundat de Rouffach. La ville reste rattachée au Mundat jusqu’à la révolution et connaît son âge d’or entre le XVIème et XVIIIème siècle, malgré quelques soubresauts tels que la peste ou un fort appauvrissement lors de la guerre de trente ans.
Le village, aujourd’hui, de petite taille avec ses 1 600 habitants, vit principalement du tourisme et du vin.

This Egyptian Goose is actually related to modern shelducks, and shares it's genus with several extinct varieties!
"Mount Franklin is an extinct volcano. It was known as Lalgambook by the local Jajowurrong people. In 1841 Sir John Franklin, Lieut-Governor of Van Dieman's Land, modestly named the mountain after himself."
E.S. Parker established the Jim Crow Aboriginal Station at Mount Franklin. In 1852 diggings were discovered that took the same name; the following year the Dry Diggings were discovered. The district soon developed as a gold-mining centre."
Palaeosinopa dideiphoides, an otter like mammal from the extinct Paniolestidae family, lived along lakes during the Eocene in what is now southwestern Wyoming. Preserved gut contents tells us this amimal fed on fish. This replica of a fossil found in the Lower Eocene Green River Formation (50 MYA) hangs on display at the Wyoming Dinosaur Center in Thermopolis, Wyoming.
Like a prehistoric beast, it waits in a field for another chance. Rusty and forlorn; the last of its kind.
Koko Crater (Hawaiian: Kohelepelepe or Puʻu Mai) is an extinct tuff cone located on the Hawaiian island of Oʻahu near Hawaiʻi Kai. It is a part of the Honolulu Volcanics, which were craters that formed as vents of the Koʻolau Volcano during its rejuvenation stage. During World War II, the U.S. military built bunkers on top of Koko Crater with a railroad leading to its summit. In 1966, the air force ceded administration of Koko Crater over to the City of Honolulu. It was then renamed to the Koko Head Regional Park. Within this park is the Koko Crater Trail, which is a 1.8-mile-long trail that uses the now-abandoned railroad as its pathway. The trail heads up 990 ft and 1,048 railroad cross-ties at a very steep incline, and the views at the Koko Head Crater summit are 1,208 ft above sea level.
The abandoned railway trail can be seen as the faint 'line' up the side of the crater in the photograph above (starts just above the baseball/softball field and ends at the peak of the crater). This photo was taken from the Hawai'i Kai Lookout along the side of Kalanianaʻole Highway.
Three bracketed photos were taken with a handheld Nikon D7200 and combined with Photomatix Pro to create this HDR image. Additional adjustments were made in Photoshop CS6.

An extinct speces Urania sloanus, or Sloane's urania, was a species of moth of the family Uraniidae endemic to Jamaica. It was last reported in 1894 or 1895, but possibly survived until at least 1908. The species was first described by Pieter Cramer in 1779.
The specific epithet sloanus honours Sir Hans Sloane (1660–1753), an English collector whose collection became the foundation of the British Museum.
Not exactly a household brand name, but this is the logo from my old film SLR, a mid seventies classic!
HMM!
The Old Town is a bustling area of centuries-old buildings and narrow alleys. At its heart, perched on an extinct volcano, Edinburgh Castle is home to Scotland’s crown jewels. The Royal Mile, a steep street lined with traditional pubs, casual eateries, souvenir shops and small museums, runs from the castle to the Scottish Parliament and the Palace of Holyroodhouse, the Queen’s Scottish residence.

Been through National Park lots of times but don't often get to see these extinct volcanos very often as the weather is usually bad but this day you could just see them just!
This is the crater of Mt Eden, the volcano overlooking the beautiful city of Auckland. Obviously there hasn't been much volcanic activity in recent years.

First identified from dinosaur-age fossils. it was thought to be extinct. The dawn redwood, Metasequoia glyptostroboides.
Then in 1941 a living specimen was discovered during a survey of Sichuan and Hubei provinces, China. Seeds were later collected and raised in arboreta worldwide. Specimens are now widely available for planting. In the wild it exists in only a few scattered stands in China where it is has protected status.
The dawn redwood is one of the few deciduous conifers.

This old and tall tree at Sandringham may well have grown from one of the original seeds brought from China.
