The Atlantic puffin (Fratercula arctica), also known as the common puffin, is a species of seabird in the auk family. It is the only puffin native to the Atlantic Ocean; two related species, the tufted puffin and the horned puffin being found in the northeastern Pacific. The Atlantic puffin breeds in Russia, Iceland, Ireland, Britain, Norway, Greenland, Newfoundland and Labrador, Nova Scotia, and the Faroe Islands, and as far south as Maine in the west and France in the east. It is most commonly found in the Westman Islands, Iceland. Although it has a large population and a wide range, the species has declined rapidly, at least in parts of its range, resulting in it being rated as vulnerable by the IUCN. On land, it has the typical upright stance of an auk. At sea, it swims on the surface and feeds on zooplankton, small fish, and crabs, which it catches by diving underwater, using its wings for propulsion.
This puffin has a black crown and back, pale grey cheek patches, and a white body and underparts. Its broad, boldly marked red-and-black beak and orange legs contrast with its plumage. It moults while at sea in the winter, and some of the brightly coloured facial characteristics are lost, with colour returning during the spring. The external appearances of the adult male and female are identical, though the male is usually slightly larger. The juvenile has similar plumage, but its cheek patches are dark grey. The juvenile does not have brightly coloured head ornamentation, its bill is narrower and is dark grey with a yellowish-brown tip, and its legs and feet are also dark. Puffins from northern populations are typically larger than in the south and these populations are generally considered a different subspecies.
Spending the autumn and winter in the open ocean of the cold northern seas, the Atlantic puffin returns to coastal areas at the start of the breeding season in late spring. It nests in clifftop colonies, digging a burrow in which a single white egg is laid. Chicks mostly feed on whole fish and grow rapidly. After about 6 weeks, they are fully fledged and make their way at night to the sea. They swim away from the shore and do not return to land for several years.
Colonies are mostly on islands with no terrestrial predators, but adult birds and newly fledged chicks are at risk of attacks from the air by gulls and skuas. Sometimes, a bird such as an Arctic skua or blackback gull can cause a puffin arriving with a beak full of fish to drop all the fish the puffin was holding in its mouth. The puffin's striking appearance, large, colourful bill, waddling gait, and behaviour have given rise to nicknames such as "clown of the sea" or "sea parrot". It is the official bird of the Canadian province of Newfoundland and Labrador. (Full article...)
The Boreray, also known as the Boreray Blackface or Hebridean Blackface, is a breed of sheep originating on the St Kilda archipelago off the west coast of Scotland and surviving as a feral animal on one of the islands, Boreray. The breed was once reared for meat and wool, but is now used mainly for conservation grazing. The Boreray is one of the Northern European short-tailed sheep group of breeds.
It is one of the rarest breeds of sheep in the United Kingdom. The breed is classed as "Category 3: Vulnerable" by the Rare Breeds Survival Trust, because 500–900 breeding ewes are known to exist. It had previously been the only breed classed in "Category 2: Critical" but by 2017 the population had grown. (Full article...)
The corn crake, corncrake or landrail (Crex crex) is a bird in the rail family. It breeds in Europe and Asia as far east as western China, and migrates to Africa for the Northern Hemisphere's winter. It is a medium-sized crake with buff- or grey-streaked brownish-black upperparts, chestnut markings on the wings, and blue-grey underparts with rust-coloured and white bars on the flanks and undertail. The strong bill is flesh-toned, the iris is pale brown, and the legs and feet are pale grey. Juveniles are similar in plumage to adults, and downy chicks are black, as with all rails. There are no subspecies, although individuals from the east of the breeding range tend to be slightly paler than their western counterparts. The male's call is a loud krek krek, from which the scientific name is derived. The corn crake is larger than its closest relative, the African crake, which shares its wintering range; that species is also darker-plumaged, and has a plainer face.
The corn crake's breeding habitat is grassland, particularly hayfields, and it uses similar environments on the wintering grounds. This secretive species builds a nest of grass leaves in a hollow in the ground and lays 6–14 cream-coloured eggs which are covered with rufous blotches. These hatch in 19–20 days, and the black precocial chicks fledge after about five weeks. This crake is in steep decline across much of its former breeding range because modern farming practices often destroy nests before breeding is completed. The corn crake is omnivorous but mainly feeds on invertebrates, the occasional small frog or mammal, and plant material including grass seed and cereal grain. Threats include dogs, cats, other introduced and feral mammals, large birds, various parasites and diseases.
Although numbers have declined steeply in western Europe, this bird is classed as least concern on the IUCN Red List because of its huge range and large, apparently stable, populations in Russia and Kazakhstan. Numbers in western China are more significant than previously thought, and conservation measures have facilitated an increased population in some countries which had suffered the greatest losses. Despite its elusive nature, the loud call has ensured the corn crake has been noted in literature, and garnered a range of local and dialect names. (Full article...)
The Eriskay Pony (Scottish Gaelic: Each Beag nan Eilean or Each Èirisgeach) is a breed of pony from Scotland. It is generally grey in colour, and has a dense, waterproof coat that protects it in harsh weather. The breed developed in ancient times in the Hebrides of Scotland, and a small population remained pure and protected from crossbreeding by the remoteness of the islands. It is used for light draught work, as a mount for children, in many equestrian disciplines, and for driving.
The Rare Breeds Survival Trust considering the breed's status to be critical. There are two breed registries for the Eriskay Pony: Comann Each nan Eilean - The Eriskay Pony Society, which was formed in 1972 and has the King Charles III as society patron, and The Eriskay Pony Society was formed in 1986. Both societies are recognised as holding a studbook of origin for the breed. and resembles the exmoor pony and are usually gray but sometimes are black or bay. (Full article...)

The great auk (Pinguinus impennis), also known as the penguin or garefowl, is a species of flightless alcid that became extinct in the mid-19th century. It was the only modern species in the genus Pinguinus. It is unrelated to the penguins of the Southern Hemisphere, which were named for their resemblance to this species.
It bred on rocky, remote islands with easy access to the ocean and a plentiful food supply, a rarity in nature that provided only a few breeding sites for the great auks. During the non-breeding season, the auk foraged in the waters of the North Atlantic, ranging as far south as northern Spain and along the coastlines of Canada, Greenland, Iceland, the Faroe Islands, Norway, Ireland, and Great Britain.
The bird was 75 to 85 centimetres (30 to 33 inches) tall and weighed about 5 kilograms (11 pounds), making it the largest alcid to survive into the modern era, and the second-largest member of the alcid family overall (the prehistoric Miomancalla was larger). It had a black back and a white belly. The black beak was heavy and hooked, with grooves on its surface. During summer, great auk plumage showed a white patch over each eye. During winter, the great auk lost these patches, instead developing a white band stretching between the eyes. The wings were only 15 cm (6 in) long, rendering the bird flightless. Instead, the great auk was a powerful swimmer, a trait that it used in hunting. Its favourite prey were fish, including Atlantic menhaden and capelin, and crustaceans. Although agile in the water, it was clumsy on land. Great auk pairs mated for life. They nested in extremely dense and social colonies, laying one egg on bare rock. The egg was white with variable brown marbling. Both parents participated in the incubation of the egg for around six weeks before the young hatched. The young left the nest site after two to three weeks, although the parents continued to care for it.
The great auk was an important part of many Native American cultures, both as a food source and as a symbolic item. Many Maritime Archaic people were buried with great auk bones. One burial discovered included someone covered by more than 200 great auk beaks, which are presumed to be the remnants of a cloak made of great auks' skins. Early European explorers to the Americas used the great auk as a convenient food source or as fishing bait, reducing its numbers. The bird's down was in high demand in Europe, a factor that largely eliminated the European populations by the mid-16th century. Around the same time, nations such as Great Britain began to realize that the great auk was disappearing and it became the beneficiary of many early environmental laws, but despite that the great auk were still hunted.

The Highland (Scottish Gaelic: Bò Ghàidhealach; Scots: Heilan coo) is a Scottish breed of rustic cattle. It originated in the Scottish Highlands and the Western Islands of Scotland and has long horns and a long shaggy coat. It is a hardy breed, able to withstand the intemperate conditions in the region. The first herd-book dates from 1885; two types – a smaller island type, usually black, and a larger mainland type, usually dun – were registered as a single breed. It is reared primarily for beef, and has been exported to several other countries. (Full article...)
The North Ronaldsay or Orkney is a breed of sheep from North Ronaldsay, the northernmost island of Orkney, off the north coast of Scotland. It belongs to the Northern European short-tailed sheep group of breeds, and has evolved without much cross-breeding with modern breeds. It is a smaller sheep than most, with the rams (males) horned and ewes (females) mostly hornless. It was formerly kept primarily for wool, but now the two largest flocks are feral, one on North Ronaldsay and another on the Orkney island of Auskerry. The Rare Breeds Survival Trust lists the breed as a priority on its 2021–2022 watchlist, and they are in danger of extinction, with fewer than 600 registered breeding females in the United Kingdom.
The semi-feral flock on North Ronaldsay is the original flock that evolved to subsist almost entirely on seaweed – they are one of few mammals to do this. They are confined to the foreshore by a 1.8 m (6 ft) early 19th century drystane dyke, which completely encircles the island, forcing the sheep to evolve this unusual characteristic. The wall was built as kelping (the production of soda ash from seaweed) on the shore became uneconomical. Sheep were confined to the shore to protect the fields and crofts inside, and afterwards subsisted largely on seaweed.
This diet has caused a variety of adaptations in the sheep's digestive system. These sheep have to extract the trace element copper far more efficiently than other breeds as their diet has a limited supply of copper. This results in them being susceptible to copper toxicity, if fed on a grass diet, as copper is toxic to sheep in high quantities. Grazing habits have also changed to suit the sheep's environment. To reduce the chance of being stranded by an incoming tide, they graze at low tide and then ruminate at high tide.
A range of fleece colours are exhibited, including grey, brown and red. Meat from the North Ronaldsay has a distinctive flavour, described as "intense" and "gamey", possibly in part due to the high iodine content in their diet of seaweed. (Full article...)
The northern gannet (Morus bassanus) is a seabird, the largest species of the gannet family, Sulidae. It is native to the coasts of the Atlantic Ocean, breeding in Western Europe and Northeastern North America. It is the largest seabird in the northern Atlantic. The sexes are similar in appearance. The adult northern gannet has a mainly white streamlined body with a long neck, and long and slender wings. It is 87–100 cm (34+1⁄2–39+1⁄2 in) long with a 170–180 cm (67–71 in) wingspan. The head and nape have a buff tinge that is more prominent in breeding season, and the wings are edged with dark brown-black feathers. The long, pointed bill is blue-grey, contrasting with black, bare skin around the mouth and eyes. Juveniles are mostly grey-brown, becoming increasingly white in the five years it takes them to reach maturity.
Nesting takes place in colonies on both sides of the North Atlantic, the largest of which are at Bass Rock (75,000 pairs as of 2014), St. Kilda (60,000 pairs as of 2013) and Ailsa Craig (33,000 pairs as of 2014) in Scotland, Grassholm in Wales, and Bonaventure Island (60,000 pairs in 2009) off the coast of Quebec. Its breeding range has extended northward and eastward, with colonies being established on Russia's Kola Peninsula in 1995 and Bear Island (the southernmost island of Svalbard), in 2011. Colonies are mostly located on offshore islands with cliffs, from which the birds can more easily launch into the air. The northern gannet undertakes seasonal migrations and catches fish (which are the mainstay of its diet) by making high-speed dives into the sea.
The northern gannet was previously hunted for food in certain parts of its range, and although that practice still continues in the Outer Hebrides of Scotland and the Faroe Islands, the bird faces few other natural or man-made threats. Since its population is growing, the International Union for Conservation of Nature considers it a least-concern species. Because it is both a conspicuous and a common bird, it is referred to in several ancient myths and legends. (Full article...)
The Shetland is a small, wool-producing breed of sheep originating in the Shetland Isles, Scotland, but is now also kept in many other parts of the world. It is part of the Northern European short-tailed sheep group, and it is closely related to the extinct Scottish Dunface. Shetlands are classified as a landrace or "unimproved" breed. This breed is kept for its very fine wool, for meat, and for conservation grazing.
Although Shetlands are small and slow-growing compared to commercial breeds, they are hardy, thrifty, easy lambers, adaptable and long-lived. The Shetland breed has survived for centuries in difficult conditions and on a poor diet, but they thrive in better conditions. Shetlands retain many of their primitive survival instincts, so they are easier to care for than many modern breeds. (Full article...)
The Shetland Sheepdog, also known as the Sheltie, is a breed of herding dog that originated in the Shetland Islands of Scotland. It was formally recognized by the Kennel Club in 1909. It was originally called the Shetland Collie, but this caused controversy amongst Rough Collie breeders of the time, so the name was changed. It is a small dog, clever, vocal, willing to please, and trustworthy.
Like the Shetland pony, Shetland cattle, and the Shetland sheep, the Shetland Sheepdog is a hardy but diminutive breed developed to thrive amidst the harsh and meagre conditions of its native islands. While the Shetland still excels at herding, today it is often raised as a working dog or family pet.
The Shetland's origins are obscure, but it is not a direct descendant of the Rough Collie, which it largely resembles. Rather, the Shetland is a descendant of small specimens of the Scottish Collie and the King Charles Spaniel. They were originally a small mixed-breed dog, often only about 20 to 30 centimetres (8 to 12 inches) in height at the shoulder, and it is thought that the original Shetland herding dogs were of the Spitz type, and were crossed with Collies from mainland Britain. In the early 20th century, James Loggie added a small Rough Collie to the breeding stock, and helped establish the breed that would become the modern Shetland Sheepdog. (Full article...)
The Soay sheep is a breed of domestic sheep (Ovis aries) descended from a population of feral sheep on the 100-hectare (250-acre) island of Soay in the St Kilda Archipelago, about 65 kilometres (40 mi) from the Western Isles of Scotland. It is one of the Northern European short-tailed sheep breeds.
It remains physically similar to the wild ancestors of domestic sheep, the Mediterranean mouflon and the horned urial sheep of Central Asia. It is much smaller than modern domesticated sheep but hardier, and is extraordinarily agile, tending to take refuge amongst the cliffs when frightened. Soays may be solid black or brown, or more often blonde or dark brown with buffish-white underbelly and rump (known as lachdann in Scottish Gaelic, which is cognate to the Manx loaghtan); a few have white markings on the face.
In the early twentieth century, some Soay sheep were relocated to establish exotic flocks, such as the flock of "Park Soay" at Woburn Abbey, established by the Duke of Bedford in 1910, and selected for "primitive" characteristics. A number of Soay sheep were translocated from Soay to another of the St Kilda group, the island of Hirta by the Marquess of Bute in the 1930s, after the human population and their sheep were evacuated. The name of the island is from Old Norse Seyðoy, meaning "Island of Sheep". The breed was introduced to and live wild on Holy Isle off Arran.
Soay sheep were introduced from St Kilda to Lundy, an island in the Bristol Channel, by Martin Coles Harman soon after he purchased the island in 1925. There is also a small population living wild in and around the Cheddar Gorge in Somerset. The breed was used in experimental archaeology at Butser Ancient Farm because it closely resembles British prehistoric breeds. (Full article...)

The St Kilda field mouse (Apodemus sylvaticus hirtensis) is a subspecies of the wood mouse that is endemic to the Scottish archipelago of St Kilda, the island 40 miles (64 km) west of Benbecula in the Outer Hebrides, and 100 miles (160 km) from mainland Scotland. Unique to the islands, the mouse is believed to have arrived on the boats of Viking settlers more than a millennium ago. It is not to be confused with the St Kilda house mouse (Mus musculus muralis), a subspecies of the house mouse which is now extinct.
The last remaining human inhabitants of St Kilda abandoned the islands on 29 August 1930. Thereafter the mice that survived, even those occupying houses abandoned by the St Kildans, were field mice that had moved into the houses from the hills. The islands' house mice could not survive the harsh conditions for more than two years after the archipelago was abandoned by its human population. The islands currently have temporary human habitations. While field mice are widespread on Hirta, their concentration is more pronounced in the old village areas where holes provide access into buildings. Though rarely observed by casual visitors, the mouse is common and is present in every part of the habitat, from the harbour to the high point. (Full article...)
