The marbled godwit (Limosa fedoa) is a large migratory shorebird in the family Scolopacidae. On average, it is the largest of the four species of godwit.
In 1750 the English naturalist George Edwards included an illustration and a description of the marbled godwit in the third volume of his A Natural History of Uncommon Birds. He used the English name "The Greater American Godwit". Edwards based his hand-coloured etching on a preserved specimen that had been brought to London from the Hudson Bay area of Canada by James Isham. [2] When in 1758 the Swedish naturalist Carl Linnaeus updated his Systema Naturae for the tenth edition, he placed the marbled godwit with godwits and ibises in the genus Scolopax . Linnaeus included a brief description, coined the binomial name Scolopax fedoa and cited Edwards' work. [3] The marbled godwit is now placed in the genus Limosa that was introduced in 1760 by the French zoologist Mathurin Jacques Brisson. [4] [5] The genus name Limosa is from Latin and means "muddy", from limus, "mud". The specific epithet fedoa may be an Old English name for a godwit. [6] The word was mentioned by the English naturalist William Turner in 1544. [7] [8]
Two subspecies are recognised: [5]
The total length is 40–50 cm (16–20 in), including a large bill of 8–13 cm (3.1–5.1 in), and wingspan is 70–88 cm (28–35 in). [9] Body mass can vary from 240 to 520 g (8.5 to 18.3 oz). The average weight of 40 males was 326 g (11.5 oz) and that of 45 females was 391 g (13.8 oz). Bill length is from 73.9 to 131 mm (2.91 to 5.16 in). Among all the members of the sandpiper family, only the curlews attain sizes that significantly exceed this species. [10] [11]
Adults have long blue-grey legs and a very long pink bill with a slight upward curve and dark at the tip. The long neck, breast and belly are pale brown with dark bars on the breast and flanks. The back is mottled and dark. They show cinnamon wing linings in flight.
Marbled godwits breed in three distinct areas with their own unique route. The vast majority occur in mid-continental North America, followed by eastern Canada and the Alaska Peninsula, USA. In addition, the largest winter ranges are the Atlantic, Pacific and Gulf coasts of the US and Mexico. [12]
Godwits breeding in the western USA and Canada follow a route through the Utah stopover site, with a final arrival in the winter sites of Mexico and the Caribbean. Species breeding in eastern Canada migrate across the US, and stopover at sites along the Gulf of California and Mexico. Furthermore, those breeding in North and South Dakota winter in coastal Georgia. [12] The Bear River Migratory Bird Refuge located at Great Salt Lake in Utah (USA), is one of the most popular stopover sites for godwits in the spring and fall.
They nest on the ground, usually in short grass.
These birds forage by probing on mudflats, in marshes, or at the beach (see picture below). When the tide is out, they eat. In short grass, they may pick up insects by sight. They mainly eat insects and crustaceans, but also eat parts of aquatic plants.
When the tide is in, they roost. They often sleep by standing on one leg and tucking their bill into their body (see picture below). [13]
Their numbers were reduced by hunting at the end of the 19th century. Although they had recovered somewhat since that time, their population has declined in recent times as suitable habitat is used for farming.
The curlews are a group of nine species of birds in the genus Numenius, characterised by their long, slender, downcurved bills and mottled brown plumage. The English name is imitative of the Eurasian curlew's call, but may have been influenced by the Old French corliu, "messenger", from courir , "to run". It was first recorded in 1377 in Langland's Piers Plowman "Fissch to lyue in þe flode..Þe corlue by kynde of þe eyre". In Europe "curlew" usually refers to one species, the Eurasian curlew.
The godwits are a group of large, long-billed, long-legged and strongly migratory waders of the bird genus Limosa. Their long bills allow them to probe deeply in the sand for aquatic worms and molluscs. In their winter range, they flock together where food is plentiful. They frequent tidal shorelines, breeding in northern climates in summer and migrating south in winter. A female bar-tailed godwit made a flight of 29,000 km (18,000 mi), flying 11,680 kilometres (7,260 mi) of it without stopping. In 2020 a male bar-tailed godwit flew about 12,200 kilometres (7,600 mi) non-stop in its migration from Alaska to New Zealand, a record for avian non-stop flight.
The ruddy turnstone is a small wading bird, one of two species of turnstone in the genus Arenaria.
The common redshank or simply redshank is a Eurasian wader in the large family Scolopacidae.
The dunlin is a small wader, formerly sometimes separated with the other "stints" in the genus Erolia. The English name is a dialect form of "dunling", first recorded in 1531–1532. It derives from dun, "dull brown", with the suffix -ling, meaning a person or thing with the given quality.
The Eurasian curlew or common curlew is a wader in the large family Scolopacidae. It is one of the most widespread of the curlews, breeding across temperate Europe and Asia. In Europe, this species is often referred to just as the "curlew", and in Scotland known as the "whaup" in Scots.
The Eurasian whimbrel is a wader in the large family Scolopacidae. It is one of the most widespread of the curlews, breeding across much of subarctic Asia and Europe as far south as Scotland. This species and the Hudsonian whimbrel have recently been split, although some taxonomic authorities still consider them to be conspecific.
The grey plover or black-bellied plover is a large plover breeding in Arctic regions. It is a long-distance migrant, with a nearly worldwide coastal distribution when not breeding.
The common snipe is a small, stocky wader native to the Old World.
The bar-tailed godwit is a large and strongly migratory wader in the family Scolopacidae, which feeds on bristle-worms and shellfish on coastal mudflats and estuaries. It has distinctive red breeding plumage, long legs, and a long upturned bill. Bar-tailed godwits breed on Arctic coasts and tundra from Scandinavia to Alaska, and overwinter on coasts in temperate and tropical regions of the Old World, Australia, and New Zealand. The migration of the subspecies Limosa lapponica baueri across the Pacific Ocean from Alaska to New Zealand is the longest known non-stop flight of any bird, and also the longest journey without pausing to feed by any animal. The round-trip migration for this subspecies is over 29,000 km (18,020 mi).
The black-tailed godwit is a large, long-legged, long-billed shorebird first described by Carl Linnaeus in 1758. It is a member of the godwit genus, Limosa. There are four subspecies, all with orange head, neck and chest in breeding plumage and dull grey-brown winter coloration, and distinctive black and white wingbar at all times.
The red-necked phalarope, also known as the northern phalarope and hyperborean phalarope, is a small wader. This phalarope breeds in the Arctic regions of North America and Eurasia. It is migratory, and, unusually for a wader, winters at sea on tropical oceans.
The red phalarope or grey phalarope is a small wader. This phalarope breeds in the Arctic regions of North America and Eurasia. It is migratory, and, unusually for a wader, migrating mainly on oceanic routes and wintering at sea on tropical oceans.
The orange-winged amazon, also known locally as orange-winged parrot and loro guaro, is a large amazon parrot. It is a resident breeding bird in tropical South America, from Colombia, Trinidad and Tobago south to Peru, Bolivia and central Brazil. Its habitat is forest and semi-open country. Although common, it is persecuted as an agricultural pest and by capture for the pet trade. It is also hunted as a food source. Introduced breeding populations have been reported in Puerto Rico and Tenerife in the Canary Islands.
The red fody, also known as the Madagascar fody in Madagascar, red cardinal fody in Mauritius, or common fody, is a small bird native to Madagascar and introduced to various other islands in the Indian Ocean. It is a common bird within its restricted range, and the International Union for Conservation of Nature has assessed its conservation status as being of "least concern".
The white-headed munia is a species of estrildid finch found in Indonesia, Malaysia, Singapore, Thailand and Vietnam. This species is also introduced to Portugal. It is found in wetlands habitat. The status of the species is evaluated as Least Concern.
The Cape wagtail, also known as Wells's wagtail, is a small insectivorous bird which is widespread in southern Africa. It frequents water's edge, lawns and gardens. It is a mostly resident, territorial species, but has been known to undertake limited altitudinal migration or form flocks outside of the breeding season. Like other wagtails they are passerine birds of the family Motacillidae, which also includes the pipits and longclaws.
The vervain hummingbird is a species of hummingbird in tribe Mellisugini of subfamily Trochilinae, the "bee hummingbirds". It is found on Hispaniola and Jamaica.
The opal-rumped tanager is a species of bird in the family Thraupidae. It is found in the Amazon and Atlantic Forest of South America. The population of the Atlantic Forest has a far paler chest than the other populations, and has often been considered a separate species as the silvery-breasted tanager. Today most authorities treat it as a subspecies of the opal-rumped tanager.
In the 10th edition of Systema Naturae, published in 1758, the Swedish naturalist Carl Linnaeus described 554 species of bird and gave each a binomial name.
