21-7-2024 VIGUR ISLAND, ICELAND - ATLANTIC PUFFIN (Fratercula arctica)

A sharply dressed black-and-white seabird with a huge, multicolored bill, the Atlantic Puffin is often called the clown of the sea. It breeds in burrows on islands in the North Atlantic, and winters at sea. In flight, puffins flap their small wings frantically to stay aloft—but underwater those wings become powerful flippers that allow the birds to catch small fish one by one until they have a beak full. This long-lived bird, once widely hunted, is reestablishing its small range in the U.S., although warming ocean waters are causing breeding failures in other parts of the North Atlantic.

Puffin chicks are known as “pufflings.”

Atlantic Puffins occur across the North Atlantic from Canada to Norway and south to Spain.

Like many seabirds, the Atlantic Puffin is long-lived, averaging 30 plus years. And like other birds with long lifespans, the young take several years to mature. Puffins do not breed until they are 3–6 years old.

The Atlantic Puffin is the official bird of Newfoundland and Labrador, Canada.

Half of North America’s Atlantic Puffins breed in one location: Witless Bay, Newfoundland, Canada.

The oldest recorded Atlantic Puffin was banded as a chick in Norway and lived to be 41 years old. But it’s likely puffins can live even longer than that; it’s only relatively recently that bands durable enough to last 40 years have come into wide use.

The best time to find Atlantic Puffins is during the breeding season. From late April through August they come ashore to nest on islands—the rest of the year they’re far out at sea. In the U.S. the best bet is to take a boat trip to rocky islands off Maine. Elsewhere, puffins nest in larger numbers in Canada, Scotland, Greenland, Norway, and especially Iceland, which is home to about half the global population. In these countries, a visit to a puffin colony can provide great views of hundreds to thousands of the birds. Outside of the breeding season, you’ll likely need to take a pelagic birding trip well offshore to find one.

A lighthouse keeper on Iceland’s Westman Islands has been banding puffin chicks for more than 60 years. The islands are home to the largest puffin colony in the world, and the keeper, Oskar Sigurdsson, earned a spot in the Guinness Book of World Records for his prolific banding: more than 90,000 birds in that time, including more than 55,000 puffins.

21-7-2024 VIGUR ISLAND, ICELAND - COMMON EIDER (MALE) (Somateria mollissima)

The common eider (pronounced /ˈaɪ.dər/) (Somateria mollissima), also called St. Cuthbert's duck or Cuddy's duck, is a large (50–71 cm (20–28 in) in body length) sea-duck that is distributed over the northern coasts of Europe, North America and eastern Siberia. It breeds in Arctic and some northern temperate regions, but winters somewhat farther south in temperate zones, when it can form large flocks on coastal waters. It can fly at speeds up to 113 km/h (70 mph).

The eider's nest is built close to the sea and is lined with eiderdown, plucked from the female's breast. This soft and warm lining has long been harvested for filling pillows and quilts, but in more recent years has been largely replaced by down from domestic farm-geese and synthetic alternatives. Although eiderdown pillows or quilts are now a rarity, eiderdown harvesting continues and is sustainable, as it can be done after the ducklings leave the nest with no harm to the birds.

The common eider is both the largest of the four eider species and the largest duck found in Europe, and is exceeded in North America only by smatterings of the Muscovy duck, which only reaches North America in a wild state in southernmost Texas (and arguably south Florida where feral but non-native populations reside). It measures 50 to 71 cm (19+1⁄2 to 28 in) in length, weighs 0.81 to 3.04 kg (1 lb 12+1⁄2 oz to 6 lb 11 oz) and spans 80–110 cm (31–43 in) across the wings. The average weight of 22 males in the North Atlantic was 2.21 kg (4 lb 14 oz) while 32 females weighed an average of 1.92 kg (4 lb 3+1⁄2 oz). It is characterized by its bulky shape and large, wedge-shaped bill. The male is unmistakable, with its black and white plumage and green nape. The female is a brown bird, but can still be readily distinguished from all ducks, except other eider species, on the basis of size and head shape. The drake's display call is a strange almost human-like "ah-ooo", while the hen utters hoarse quacks. The species is often readily approachable.

21-7-2024 ISAFJORDUR, ICELAND - COMMON EIDER (JUVENILE) (Somateria mollissima)

The common eider is a large diving duck that is easily distinguishable, even at quite long distances, because of the elongated profile of the head. Adults of this species are approximately 58 cm long and weigh from 1.2–2.8 kg.

Males and females have very different plumage; the male has a black crown, belly and tail, while the rest of the plumage is white, the breast usually has a pinkish tinge. Males also have characteristic green marks on the sides of the head. The female is brown with light, closely packed bars over the whole body.

Young males are a mottled brown-black and white, the pattern of which varies with age. Young birds are difficult to distinguish from adult males in transitional plumage after the nesting season, when they are switching to their winter colours.

The male’s voice is a deep, prolonged ‘coo-roo-uh’, the female’s call is a growling ‘cor-r-r’.

21-7-2024 ISAFJORDUR, ICELAND - COMMON EIDER (FEMALE) (Somateria mollissima)

The common eider (pronounced /ˈaɪ.dər/) (Somateria mollissima), also called St. Cuthbert's duck or Cuddy's duck, is a large (50–71 cm (20–28 in) in body length) sea-duck that is distributed over the northern coasts of Europe, North America and eastern Siberia.

Drakes of the European, eastern North American and Asia/western North American races can be distinguished by minor differences in plumage and bill colour. Some authorities place the subspecies v-nigra as a separate species.

This species dives for crustaceans and molluscs, with mussels being a favoured food. The eider will eat mussels by swallowing them whole; the shells are then crushed in their gizzard and excreted. When eating a crab, the eider will remove all of its claws and legs, and then eat the body in a similar fashion.

It is abundant, with populations of about 1.5–2 million birds in both North America and Europe, and also large but unknown numbers in eastern Siberia (HBW).

21-7-2024 ISAFJORDUR, ICELAND - COMMON EIDER (FEMALE AND JUVENILE) (Somateria mollissima)

The Eider is the UK's heaviest and fastest flying duck. It's a true seaduck, rarely found away from coasts. Its reliance on coastal shellfish for food has brought it into conflict with mussel farmers. Eiders are very sociable and usually stay close to shore, riding the swell in a sandy bay or strung out in long lines beyond the breaking waves. It is an Amber List species because of its winter concentrations.

Flocks of these large sea ducks enliven northern coastlines. Males are white and black with a soft suffusion of green on the nape. Immature males are variable and messy-looking with patches of black and white. Females vary from rich rufous-brown to cold grayish, always with extensive black barring covering body and wings. Slight variation in bill shape and color across subspecies, especially obvious on males; Pacific birds have brightest orange bills, most others have greenish bills. Dives to feed on mollusks and other crustaceans. In late summer, look for flocks of females with dozens of ducklings; broods often join together. Compare females with other eider species, and note details of bill and head shape.

21-7-2024 ISAFJORDUR, ICELAND - EUROPEAN GLOBEFLOWER (Trollius europaeus)

Trollius europaeus, the globeflower, is a perennial flowering plant of the family Ranunculaceae. The plant is native to Europe and Western Asia and is a protected species in Russia and Bulgaria.

In Udmurtia, this plant is one of the national symbols of the republic, with many different objects named after it.

Trollius europaeus grows up to 60 cm high with a bright yellow, globe-shaped flower up to 3 cm across. The colourful petaloid sepals hide 5–15 inconspicuous true petals with nectaries at their base and, typically for the family, a large number of stamens. Each flower produces a large number of wrinkled follicles. The leaves are deeply divided into 3–5 toothed lobes.

It grows in damp ground in shady areas, woodland and scrub, flowering between June and August.

This species is pollinated mostly by seed-eating flies belonging to the genus Chiastocheta (Anthomyiidae).

21-7-2024 VIGUR ISLAND, ICELAND - COMMON REDSHANK (Tringa totanus)

The common redshank or simply redshank (Tringa totanus) is a Eurasian wader in the large family Scolopacidae.

The common redshank was formally described by the Swedish naturalist Carl Linnaeus in 1758 in the tenth edition of his Systema Naturae under the binomial name Scolopax totanus. It is now placed with twelve other species in the genus Tringa that Linnaeus had introduced in 1758. The genus name Tringa is the Neo-Latin name given to the green sandpiper by the Italian naturalist Ulisse Aldrovandi in 1603 based on Ancient Greek trungas, a thrush-sized, white-rumped, tail-bobbing wading bird mentioned by Aristotle. The specific totanus is from Tótano, the Italian name for this bird.

Common redshanks in breeding plumage are a marbled brown color, slightly lighter below. In winter plumage they become somewhat lighter-toned and less patterned, being rather plain greyish-brown above and whitish below. They have red legs and a black-tipped red bill, and show white up the back and on the wings in flight.

The spotted redshank (T. erythropus), which breeds in the Arctic, has a longer bill and legs; it is almost entirely black in breeding plumage and very pale in winter. It is not a particularly close relative of the common redshank, but rather belongs to a high-latitude lineage of largish shanks. T. totanus on the other hand is closely related to the marsh sandpiper (T. stagnatilis), and closer still to the small wood sandpiper (T. glareola). The ancestors of the latter and the common redshank seem to have diverged around the Miocene-Pliocene boundary, about 5–6 million years ago. These three subarctic- to temperate-region species form a group of smallish shanks with have red or yellowish legs, and in breeding plumage are generally a subdued light brown above with some darker mottling, and have somewhat diffuse small brownish spots on the breast and neck.

The common redshank is a widespread breeding bird across temperate Eurasia. It is a migratory species, wintering on coasts around the Mediterranean, on the Atlantic coast of Europe from Ireland and Great Britain southwards, and in South Asia. They are uncommon vagrants outside these areas; on Palau in Micronesia for example, the species was recorded in the mid-1970s and in 2000. A tagged redshank was spotted at Manakudi Bird Sanctuary, Kanniyakumari District of Tamil Nadu, India in the month of April 2021.

They are wary and noisy birds which will alert everything else with their loud piping call.

Redshanks will nest in any wetland, from damp meadows to saltmarsh, often at high densities. They lay 3–5 eggs.

Like most waders, they feed on small invertebrates.

The common redshank is widely distributed and quite plentiful in some regions, and thus not considered a threatened species by the IUCN. It is one of the species to which the Agreement on the Conservation of African-Eurasian Migratory Waterbirds (AEWA) applies.

21-7-2024 VIGUR ISLAND, ICELAND - COMMON EIDER (JUVENILE) (Somateria mollissima)

A particularly famous colony of eiders lives on the Farne Islands in Northumberland, England. These birds were the subject of one of the first ever bird protection laws, established by Saint Cuthbert in the year 676. About 1,000 pairs still nest there every year. Because St. Cuthbert is the patron saint of Northumberland, it was natural that the eider should be chosen as the county's emblem bird; the birds are still often called Cuddy's ducks in the area, "Cuddy" being the familiar form of "Cuthbert".

21-7-2024 VIGUR ISLAND, ICELAND - COMMON EIDER (FEMALE) (Somateria mollissima)

The common eider (pronounced /ˈaɪ.dər/) (Somateria mollissima), also called St. Cuthbert's duck or Cuddy's duck, is a large (50–71 cm (20–28 in) in body length) sea-duck that is distributed over the northern coasts of Europe, North America and eastern Siberia.

19-7-2024 AT SEA, ICELAND - BLACK LEGGED KITTIWAKE (Rissa tridactyla)

The black-legged kittiwake (Rissa tridactyla) is a seabird species in the gull family Laridae.

This species was first described by Carl Linnaeus in his landmark 1758 10th edition of Systema Naturae as Larus tridactylus. The English name is derived from its call, a shrill 'kittee-wa-aaake, kitte-wa-aaake'. The genus name Rissa is from the Icelandic name rita for this bird, and the specific tridactyla is from Ancient Greek tridaktulos, "three-toed", from tri-, "three-" and daktulos, "toe".

In North America, this species is known as the black-legged kittiwake to differentiate it from the red-legged kittiwake, but in Europe, where it is the only member of the genus, it is often known just as kittiwake.

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 off 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.

21-7-2024 ISAFJORDUR, ICELAND - ARCTIC TERN (Sterna paradisaea)

The Arctic tern (Sterna paradisaea) is a tern in the family Laridae. This bird has a circumpolar breeding distribution covering the Arctic and sub-Arctic regions of Europe (as far south as Brittany), Asia, and North America (as far south as Massachusetts). The species is strongly migratory, seeing two summers each year as it migrates along a convoluted route from its northern breeding grounds to the Antarctic coast for the southern summer and back again about six months later. Recent studies have shown average annual round-trip lengths of about 70,900 km (44,100 mi) for birds nesting in Iceland and Greenland and about 48,700 km (30,300 mi) for birds nesting in the Netherlands. These are by far the longest migrations known in the animal kingdom. The Arctic tern nests once every one to three years (depending on its mating cycle).

Arctic terns are medium-sized birds. They have a length of 28–39 cm (11–15 in) and a wingspan of 65–75 cm (26–30 in). They are mainly grey and white plumaged, with a red/orange beak and feet, white forehead, a black nape and crown (streaked white), and white cheeks. The grey mantle is 305 mm (12.0 in), and the scapulae are fringed brown, some tipped white. The upper wing is grey with a white leading edge, and the collar is completely white, as is the rump. The deeply forked tail is whitish, with grey outer webs.

Arctic terns are long-lived birds, with many reaching fifteen to thirty years of age. They eat mainly fish and small marine invertebrates. The species is abundant, with an estimated two million individuals. While the trend in the number of individuals in the species as a whole is not known, exploitation in the past has reduced this bird's numbers in the southern reaches of its ranges.

The Arctic tern has a continuous worldwide circumpolar breeding distribution; there are no recognized subspecies. It can be found in coastal regions in cooler temperate parts of North America and Eurasia during the northern summer. During the southern summer, it can be found at sea, reaching the northern edge of the Antarctic ice.

The Arctic tern is famous for its migration; it flies from its Arctic breeding grounds to the Antarctic and back again each year. The shortest distance between these areas is 19,000 km (12,000 mi). The long journey ensures that this bird sees two summers per year and more daylight than any other creature on the planet. One example of this bird's remarkable long-distance flying abilities involves an Arctic tern ringed as an unfledged chick on the Farne Islands, Northumberland, UK, in the northern summer of 1982 that reached Melbourne, Australia in October, just three months after fledging – a journey of more than 22,000 km (14,000 mi). Another example is that of a chick ringed in Labrador, Canada, on 23 July 1928. It was found in South Africa four months later.

21-7-2024 VIGUR ISLAND, ICELAND - BLACK GUILLEMOT (Cepphus grylle)

The black guillemot is a circumpolar species distributed in the boreal, low arctic and high arctic regions of the north Atlantic and arctic oceans and breeding between 43° and 82°N. The 5 listed subspecies inhabit different parts of this range. In North America, they can be found as far south as the Gulf of Maine and New England and across parts of the northern coast of North America as far as Alaska, where they are replaced by the pigeon guillemot in the North Pacific. In Europe and Asia, they are found from the British Isles and Northward across the northern coast of Asia. They are one of the few birds to breed on Surtsey, Iceland, a new volcanic island. It is a fairly common breeding bird in western and northern Scotland and Ireland. In Great Britain, they only breed at St. Bees Head in Cumbria, the Isle of Man and on east Anglesey in north Wales. Approximately 40% of the population breeds in the high arctic where the largest colonies are found, 30% in the low arctic, and 30% in boreal waters. In the winter, some of the birds in the high arctic waters are forced south by the winter ice making them seasonal migrants, but in more temperate zones the species is essentially resident.

Typically restricted to rocky shores, black guillemots utilize the cliffs, crevices and boulders for their nests, hunting the inshore waters for benthic prey. Compared to other auks, they forage fairly close to the colony, in the breeding season mostly in inshore waters more than 50m in depth, farther afield in the winter months.

One of the early ornithologists that described aspects of the behaviour of the black guillemot was Edmund Selous (1857–1934) in his book The Bird Watcher in the Shetlands (1905). In the chapter titled 'From the Edge of a Precipice he writes for instance that sometimes the black guillemots carry a fish they have caught in their beak for hours. He also gives further details about the behaviour.

Black guillemots are coastal foragers with diets typically associated with benthic and kelp-forest prey. They dive between 15-20m to catch their prey, but can dive to a depth of at least 43m. They use their wings to propel themselves forward and their feet to steer.  Small prey are swallowed underwater whole. Guillemots bring larger prey to the surface to soften in their bill before swallowing whole.  Guillemots are single-prey loaders, meaning they bring single prey items back to their chicks during the chick-rearing period. This limits the spatial range that parents can forage for food, as chicks must receive a high number of energy-rich prey items throughout each day.  Black guillemot diets include sculpins, butterfish, rock gunnel, northern sandlance, herring, jellyfish, mollusks, and other small crustaceans. 

A number of threats face Black guillemots. Black guillemots have been shown to be vulnerable to several species of predators including American Mink, Great Skua, gulls, and Otter Lutra Lutra, as well as introduced species like the Brown Rat and feral cats.  One large colony on an island in the Baltic Sea (approximately 2600 individuals) was wiped out by American Mink in the early 2000s.  Because Black guillemots forage close to shore, they tend to be exposed to more pollution than further oceangoing seabirds. Additional sources of pressure include fisheries bycatch, habitat destruction, and climate change. 

21-7-2024 VIGUR ISLAND, ICELAND - PURPLE SANDPIPER (Calidris maritima)

The purple sandpiper (Calidris maritima) is a small shorebird in the sandpiper family Scolopacidae. This is a hardy sandpiper that breeds in the arctic and subarctic regions of Eurasia and North America and winters further south on the Atlantic coast.

Adults have short yellow legs and a medium thin dark bill with a yellow base. The body is dark on top with a slight purplish gloss and mainly white underneath. The breast is smeared with grey and the rump is black. They measure 20–22 cm (7.9–8.7 in) in length and 42–46 cm (17–18 in) across the wings, and weight is from 50–105 g (1.8–3.7 oz).

Standard Measurements[10][11]

Total Body Length 210–240 mm (8.1–9.5 in)

Weight 70 g (2.5 oz)

Wingspan 430 mm (17 in)

Wing 117.9–130 mm (4.64–5.12 in)

Tail 55.9–63 mm (2.20–2.48 in)

Culmen 27.2–32 mm (1.07–1.26 in)

Tarsus 22–23.8 mm (0.87–0.94 in)

The purple sandpiper's breeding range extends from the arctic islands of northern Canada, eastwards to Greenland, Iceland, Svalbard and northern Scandinavia across to Western Siberia and the Taymyr Peninsula. In the high arctic the sandpiper breeds at low altitude on the tundra, sometimes far from the coastline, but in the subarctic regions of Sweden and Norway it breeds on barren mountain sides near the limit of the frozen ground. Birds breeding at high latitudes migrate south and spend the winter on rocky shores on both sides of the north Atlantic. They winter along the North America coast as far south as South Carolina and on the eastern Atlantic coast as far south as France and northern Iberia.

Birds wintering in northern Scotland and southwest Ireland migrate to Canada (Baffin Island and Devon Island) to breed.

In Britain, these birds occur in winter in good numbers principally along the east and south coasts, where they favour rocky shorelines adjacent to the sea. It is much rarer as a breeding bird, found only in a localised area of the Cairngorms National Park, where 1–3 pairs have bred since 1978. Records of breeding by this species in the UK are monitored and archived by the Rare Breeding Birds Panel.

They are late migrants and move to rocky, ice-free Atlantic coasts in winter.[citation needed] Most go no further south than North Carolina and northern Portugal. They are fairly gregarious, forming small flocks, often with ruddy turnstones. This species is tame and approachable.

Their breeding habitat is the northern tundra on Arctic islands in Canada and coastal areas in Greenland and northwestern Europe. They can breed at one year of age. The male makes several scrapes on the ground; the female chooses one and lays 3 or 4 eggs. These are olive with brown blotches and are approximately 37 mm × 26 mm (1.5 in × 1.0 in) in size. The male takes the major responsibility for incubation of the eggs which hatch in 21–22 days. The chicks are covered with dense down. The upperparts have black and cinnamon patches with white specks; the underparts are mainly white. Usually only the male tends the chicks which can feed themselves. The maximum age recorded from ring-recovery data in Europe is 20 years and 9 months for a bird recovered in Sweden.

These birds forage on rocky coasts, picking up food by sight. They mainly eat arthropods and molluscs, mainly littorinids and mussels, also some plant material. One of the main staples are seaweed flies of the Coelopa genera (C. frigida).

The purple sandpiper has an extremely large range and although the population appears to be decreasing, the population is very large. 

21-7-2024 VIGUR ISLAND, ICELAND - ATLANTIC PUFFIN (Fratercula arctica)

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 are 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. 

The Atlantic puffin is a bird of the colder waters of the North Atlantic Ocean. It breeds on the coasts of northwest Europe, the Arctic fringes, and eastern North America. More than 90% of the global population is found in Europe (4,770,000–5,780,000 pairs, equalling 9,550,000–11,600,000 adults) and colonies in Iceland alone are home to 60% of the world's Atlantic puffins. The largest colony in the western Atlantic (estimated at more than 260,000 pairs) can be found at the Witless Bay Ecological Reserve, south of St. John's, Newfoundland and Labrador. Other major breeding locations include the north and west coasts of Norway, the Faroe Islands, Shetland and Orkney, the west coast of Greenland, and the coasts of Newfoundland. Smaller-sized colonies are also found elsewhere in the British Isles, the Murmansk area of Russia, Novaya Zemlya, Spitzbergen, Labrador, Nova Scotia, and Maine. Islands seem particularly attractive to the birds for breeding as compared to mainland sites, likely to avoid predators.

20-7-2024 HUSAVIK, ICELAND - NOOTKA LUPINE (Lupinus nootkatensis)

In Iceland, the Nootka lupine has been designated an invasive species. The plant was introduced in the first half of the 20th century to combat erosion, speed up land reclamation and help with reforestation. Dense lupine cover and soil fertility can be gained within a relatively short time span, where the growth of the lupine is not limited by droughts. The plant has spread from the loose, eroded soil in which it was originally planted and is now found throughout the lowlands of Iceland.

The lupine is well suited for reclamation of large, barren areas because of its nitrogen fixation and rapid growth. Furthermore, it has an ability to extract phosphorus from compounds in poor soils. In spite of these good qualities, it has a tendency to become dominant and to colonize already vegetated areas such as dwarf shrub-highlands, where it overtakes the natural flora and threatens biodiversity. The growth of the Nootka lupine has led to public debate about its presence in Iceland, with some praising its improvement of soil through nitrogen fixation and the vibrant colour it brings to Iceland's landscape, and others concerned that it will eradicate native flora, particularly the favoured native crowberry and blueberry patches.

The initial expectation was for the Nootka lupine to retreat gradually along with increased fertility of the soil and give way for other species. This is evident on sites in Iceland where the lupine was introduced early, such as in Heiðmörk near Reykjavík. However, plant succession is towards a forb-rich grassland, often dominated by the invasive species Anthriscus sylvestris, meaning that careful management of lupine is necessary to prevent it from colonizing areas where its presence is not desirable.

20-7-2024 AKUREYRI, ICELAND - LESSER BLACK BACKED GULL (Larus fuscus)

The lesser black-backed gull (Larus fuscus) is a large gull that breeds on the Atlantic coasts of Europe. It is migratory, wintering from the British Isles south to West Africa. However, it has increased dramatically in North America, especially along the east coast. Formerly just a winter visitor to North America, it has increased and occurs in large numbers some winters and birds are now recorded year-round. However, there is serious concern about decline in many parts of its range. The species is on the UK Amber List because the UK is home to 40 per cent of the European population and more than half of these are found at fewer than ten breeding sites.

The lesser black-backed gull was one of the many species originally described by Carl Linnaeus in his 1758 10th edition of Systema Naturae, and it still bears its original name Larus fuscus. The scientific name is from Latin. Larus appears to have referred to a gull or other large seabird, and fuscus meant black or brown.

20-7-2024 HUSAVIK, ICELAND - REDWING (Turdus iliacus)

The redwing (Turdus iliacus) is a bird in the thrush family, Turdidae, native to Europe and the Palearctic, slightly smaller than the related song thrush.

This species was first described by Carl Linnaeus in his 1758 10th edition of Systema Naturae under its current scientific name.

The English name derives from the bird's red underwing. It is not closely related to the red-winged blackbird, a North American species sometimes nicknamed "redwing", which is an icterid, not a thrush. The binomial name derives from the Latin words turdus, "thrush", and ile "flank".

About 65 species of medium to large thrushes are in the genus Turdus, characterised by rounded heads, longish, pointed wings, and usually melodious songs. Although two European thrushes, the song thrush and mistle thrush, are early offshoots from the Eurasian lineage of Turdus thrushes after they spread north from Africa, the redwing is descended from ancestors that had colonised the Caribbean islands from Africa and subsequently reached Europe from there.

The redwing has two subspecies:

T. i. iliacus, the nominate subspecies described by Linnaeus, which breeds in mainland Eurasia.

T. i. coburni described by Richard Bowdler Sharpe in 1901, which breeds in Iceland and the Faroe Islands and winters from western Scotland and Ireland south to northern Spain. It is darker overall, and marginally larger than the nominate form.

It is 20–24 cm long with a wingspan of 33–34.5 cm and a weight of 50–75 g. The sexes are similar, with plain brown backs and with dark brown spots on the white underparts. The most striking identification features are the red flanks and underwing, and the creamy white stripe above the eye. Adults moult between June and September, which means that some start to replace their flight feathers while still feeding young.

The male has a varied short song, and a whistling flight call. Redwings show a distinct dialectic variation in song, having a considerable similarity in song patterns among birds within a local population.

The Redwing song consists of a number of introductory elements of descending or ascending frequency. These elements may be of pure tonal quality, or of a more harsh quality (varying degrees of frequency modulations or "trills"). After the introductory elements, a fast and more complex song pattern often follows. It is the introductory elements which show a geographic variation. The boundaries of any given dialect may vary but in a rural and forested environment in Norway the average size of these dialect areas is around 41.5 km2.

It breeds in northern regions of Europe and the Palearctic, from Iceland south to northernmost Scotland, and east through Scandinavia, the Baltic States, northern Poland and Belarus, and through most of Russia to about 165°E in Chukotka Autonomous Okrug. In recent years it has expanded its range slightly, both in eastern Europe where it now breeds south into northern Ukraine, and in southern Greenland, where the Qaqortoq area was colonised in 1990–1991.

It is often replaced by the related ring ouzel in areas of higher altitude.

It is migratory, wintering in western, central and southern Europe, north-west Africa, and south-west Asia east to northern Iran. Birds in some parts of the west of the breeding range (particularly south-western Norway) may be resident, not migrating at all, while those in the far east of the range migrate at least 6,500–7,000 km to reach their wintering grounds.

There are multiple records of vagrants from the north-east coast of North America, as well as two sightings on the north-west coast (one in Washington in 2005, and one in Seward, Alaska in November 2011).

Migrating and wintering birds often form loose flocks of 10 to 200 or more birds, often feeding together with fieldfares, common blackbirds and starlings, sometimes also with mistle thrushes, song thrushes, and ring ouzels. Unlike the song thrush, the more nomadic redwing does not tend to return regularly to the same wintering areas.

The movement occurs in the Autumn to early Winter and they often move at night making a "Tseep" contact call that can carry a long distance.

Nests are often constructed on the ground.

It breeds in conifer and birch forest and tundra. Redwings nest in shrubs or on the ground, laying four to six eggs in a neat nest. The eggs are typically 2.6 x 1.9 centimetres in size and weigh 4.6 grammes, of which 5% is shell, and which hatch after 12–13 days. The chicks fledge at 12–15 days, but the young remain dependent on their parents for a further 14 days.

It is omnivorous, eating a wide range of insects and earthworms all year, supplemented by berries in autumn and winter, particularly of rowan Sorbus aucuparia and hawthorn Crataegus monogyna.

A Russian study of blood parasites showed that all the fieldfares, redwings and song thrushes sampled carried haematozoans, particularly Haemoproteus and Trypanosoma.

The redwing has an extensive range, estimated at 10 million square kilometres (3.8 million square miles), and an estimated population of 26 to 40 million individuals in Europe alone. The European population forms approximately 40% of the global population, thus the very preliminary estimate of the global population is 98 to 151 million individuals. The species is believed to approach the thresholds for the population decline criterion of the IUCN Red List (i.e., declining more than 30% in ten years or three generations), and is therefore precautionarily uplisted to near threatened. Numbers can be adversely affected by severe winters, which may cause heavy mortality, and cold wet summers, which reduce breeding success.

20-7-2024 HUSAVIK, ICELAND - COMMON RINGED PLOVER (Charadrius hiaticula)

The common ringed plover or ringed plover (Charadrius hiaticula) is a small plover that breeds across much of northern Eurasia, as well as Greenland. The genus name Charadrius is a Late Latin word for a yellowish bird mentioned in the fourth-century Vulgate. It derives from Ancient Greek kharadrios a bird found in ravines and river valleys (kharadra, "ravine"). The specific hiaticula is Latin and has a similar meaning to the Greek term, coming from hiatus, "cleft" and -cola, "dweller" (colere, "to dwell").

Adults are 17–19.5 cm (6.7–7.7 in) in length with a 35–41 cm (14–16 in) wingspan. They have a grey-brown back and wings, a white belly, and a white breast with one black neckband. They have a brown cap, a white forehead, a black mask around the eyes and a short orange and black bill. The legs are orange and only the outer two toes are slightly webbed, unlike the slightly smaller but otherwise very similar semipalmated plover, which has all three toes slightly webbed, and also a marginally narrower breast band; it was in former times included in the present species. Juvenile ringed plovers are duller than the adults in colour, with an often incomplete grey-brown breast band, a dark bill and dull yellowish-grey legs.

This species differs from the smaller little ringed plover in leg colour, the head pattern, and the lack of an obvious yellow eye-ring.

The common ringed plover's breeding habitat is open ground on beaches or flats across northern Eurosiberia and in Arctic northeast Canada. Some birds breed inland, and in western Europe they nest as far south as northern France. They nest on the ground in an open area with little or no plant growth.

If a potential predator approaches the nest, the adult will walk away from the scrape, calling to attract the intruder and feigning a broken wing. Once the intruder is far enough from the nest, the plover flies off.

Common ringed plovers are migratory and winter in coastal areas south to Africa. In Norway, geolocators have revealed that adult breeding birds migrate to West Africa. Many birds in Great Britain and northern France are resident throughout the year.

These birds forage for food on beaches, tidal flats and fields, usually by sight. They eat insects, crustaceans and worms.
