The Duclair duck is a dual purpose duck breed named after the town of Duclair in Normandy. It is a type of Rouen duck and is also described as being similar to the Swedish Blue. [1] [2] Official standards were established for the Duclair on November 23, 1923.
Duclair ducks are considered excellent for roast duck. [1] It has been described as "tasting like a cross between veal and lamb" by Alain Ducasse and Daniel Boulud, and as "gamy". [3]
Males weigh up to 6.6 pounds (3.0 kg) and females up to 5.5 pounds (2.5 kg). There are two color varieties; a black and a blue. Both have a single white feather on each wing and a white bib. Eggs have a blue-green shell. Duclair ducks are very handsome. [1] [4]
Duclair ducks are known to lay up to 80 - 100 eggs per year. It takes a minimum of 26 to 28 days for these duckling eggs to hatch. [5] Duclair duck eggs are noted due to their size and numerous health benefits. The eggs are significantly larger than a chicken egg and carry double the amount of Vitamin A and six times the amount of Vitamin D. [5] [6] Duclair ducklings can take up to 8 weeks to learn to fly and are strong and stable in their youth. They do not often perish by disease and can adapt easily to differing climates. [7]
Duclair ducks live off a simple diet of a variety of insects and crustaceans. They consume flies, beetles, worms, and dragonflies. [8] The duclair duck is an excellent forager and are able to fend for themselves in the wild.
Duclair ducks are considered to be a very tame and very calm duck. [9] This makes the Duclair duck a very good choice for a beginner pet. According to Kim Irvine of domestic animal breeds, this is the best breed of ducklings you can get as a first time owner of ducklings. They roam freely and also take care of themselves. Another plus is that the Duclair duck does not have any known diseases, so worrying about catching a disease from a duck or the other potential animals you take in as a pet. [10]
Duclair ducks are most widely known in the culinary world for their meat and egg production. They are attractive to chefs and consumers due to their rapid growth rate. A duclair duck is smaller than an average duck, but due to its affinity to disease and excellent taste, it is a highly sought after meat that is mainly served in high-scale restaurants. Despite being low maintenance pets, a majority of Duclair ducks are bred to produce meat.
Duclair Ducks have three eyelids with the third found on the side of the eye. The third eyelid is called the nictitating membrane. [9] The Duclair duck, whether it is flying or swimming underwater, has superior vision to other species of ducks. In fact, whenever Duclair ducks swim underwater/fly, they blink their eyelids. When blinking their eyelids, it acts as a windshield wiper to clear their eyes, which then helps them when diving underwater, and also helps when drying out eyes when flying. [5]
Dolly was a female Finnish Dorset sheep and the first mammal cloned from an adult somatic cell. She was cloned by associates of the Roslin Institute in Scotland, using the process of nuclear transfer from a cell taken from a mammary gland. Her cloning proved that a cloned organism could be produced from a mature cell from a specific body part. Contrary to popular belief, she was not the first animal to be cloned.
Poultry are domesticated birds kept by humans for their eggs, their meat or their feathers. These birds are most typically members of the superorder Galloanserae (fowl), especially the order Galliformes. The term also includes birds that are killed for their meat, such as the young of pigeons but does not include similar wild birds hunted for sport or food and known as game. The word "poultry" comes from the French/Norman word poule, itself derived from the Latin word pullus, which means small animal.
Duck is the common name for numerous species of waterfowl in the family Anatidae. Ducks are generally smaller and shorter-necked than swans and geese, which are members of the same family. Divided among several subfamilies, they are a form taxon; they do not represent a monophyletic group, since swans and geese are not considered ducks. Ducks are mostly aquatic birds, and may be found in both fresh water and sea water.
Acanthocephala is a phylum of parasitic worms known as acanthocephalans, thorny-headed worms, or spiny-headed worms, characterized by the presence of an eversible proboscis, armed with spines, which it uses to pierce and hold the gut wall of its host. Acanthocephalans have complex life cycles, involving at least two hosts, which may include invertebrates, fish, amphibians, birds, and mammals. About 1420 species have been described.
The mallard or wild duck is a dabbling duck that breeds throughout the temperate and subtropical Americas, Eurasia, and North Africa, and has been introduced to New Zealand, Australia, Peru, Brazil, Uruguay, Argentina, Chile, Colombia, the Falkland Islands, and South Africa. This duck belongs to the subfamily Anatinae of the waterfowl family Anatidae. The male birds (drakes) have a glossy green head and are grey on their wings and belly, while the females have mainly brown-speckled plumage. Both sexes have an area of white-bordered black or iridescent blue feathers called a speculum on their wings; males especially tend to have blue speculum feathers. The mallard is 50–65 cm (20–26 in) long, of which the body makes up around two-thirds the length. The wingspan is 81–98 cm (32–39 in) and the bill is 4.4 to 6.1 cm long. It is often slightly heavier than most other dabbling ducks, weighing 0.7–1.6 kg (1.5–3.5 lb). Mallards live in wetlands, eat water plants and small animals, and are social animals preferring to congregate in groups or flocks of varying sizes. This species is the main ancestor of most breeds of domestic ducks.
The redhead is a medium-sized diving duck. The scientific name is derived from Greek aithuia, an unidentified seabird mentioned by authors including Hesychius and Aristotle, and Latin americana, of America. The redhead is 37 cm (15 in) long with an 84 cm (33 in) wingspan. Redhead weight ranges from 2.0 to 2.5 lbs, with males weighing an average of 2.4 lbs and females weighing an average of 2.1 lbs. It belongs to the genus Aythya, together with 11 other described species. The redhead and the common pochard form a sister group which together is sister to the canvasback.
The American black duck is a large dabbling duck in the family Anatidae. It was described by William Brewster in 1902. It is the heaviest species in the genus Anas, weighing 720–1,640 g (1.59–3.62 lb) on average and measuring 54–59 cm (21–23 in) in length with a 88–95 cm (35–37 in) wingspan. It somewhat resembles the female and eclipse male mallard in coloration, but has a darker plumage. The male and female are generally similar in appearance, but the male's bill is yellow while the female's is dull green with dark marks on the upper mandible. It is native to eastern North America. During the breeding season, it is usually found in coastal and freshwater wetlands from Saskatchewan to the Atlantic in Canada and the Great Lakes and the Adirondacks in the United States. It is a partially migratory species, mostly wintering in the east-central United States, especially in coastal areas.
The greater scaup, just scaup in Europe or, colloquially, "bluebill" in North America, is a mid-sized diving duck, larger than the closely related lesser scaup. It spends the summer months breeding in Alaska, northern Canada, Siberia, and the northernmost reaches of Europe. During the winter, it migrates south to the coasts of North America, Europe, and Japan.
The Aylesbury duck is a breed of domesticated duck, bred mainly for its meat and appearance. It is a large duck with pure white plumage, a pink bill, orange legs and feet, an unusually large keel, and a horizontal stance with its body parallel to the ground. The precise origins of the breed are unclear, but raising white ducks became popular in Aylesbury, Buckinghamshire, England, in the 18th century owing to the demand for white feathers as a filler for quilts. Over the 19th century selective breeding for size, shape and colour led to the Aylesbury duck.
The surf scoter is a large sea duck native to North America. Adult males are almost entirely black with characteristic white patches on the forehead and the nape and adult females are slightly smaller and browner. Surf scoters breed in Northern Canada and Alaska and winter along the Pacific and Atlantic coasts of North America. Those diving ducks mainly feed on benthic invertebrates, mussels representing an important part of their diet.
The Muscovy duck is a large duck native to the Americas. Small wild and feral breeding populations have established themselves in the United States, particularly in Florida, Louisiana, Massachusetts, the Big Island of Hawaii, as well as in many other parts of North America, including southern Canada. Feral Muscovy ducks are found in New Zealand, Australia, and in parts of Europe.
The Laysan duck, also known as the Laysan teal, is a dabbling duck endemic to the Hawaiian Islands. Fossil evidence reveals that Laysan ducks once lived across the entire archipelago, but today survive only on Laysan Island and two atolls. The duck has several physical and behavioral traits linked to the absence of ground-based predators in its habitat. By 1860, the ducks had disappeared from everywhere except Laysan Island. The introduction of European rabbits by guano miners at the end of the 19th century brought the bird to the brink of extinction in 1912, with twelve surviving individuals. Rabbits were eradicated from the island in 1923 and numbers of Laysan ducks began to rise, reaching 500 by the 1950s. In an effort to ensure the long-term future of this duck, 42 birds were translocated to Midway Atoll National Wildlife Refuge in 2002. These thrived in their new surroundings, and another group were later relocated to Kure Atoll.
An egg is the organic vessel containing the zygote in which an embryo develops until it can survive on its own, at which point the animal hatches. An egg results from fertilization of an egg cell. Most arthropods, vertebrates, and mollusks lay eggs, although some, such as scorpions, do not.
The rosy-billed pochard, alternatively named rosybill or rosybill pochard, is a member of family Anatidae. Though classified as a diving duck, this pochard feeds more like a dabbling duck feeding on seeds roots, sedges, aquatic plants and other grasses. Netta is Ancient Greek for "duck" and peposaca is a transcription of the Guaraní name of this species which means "showy wings", referring to the broad white stripe that is only visible with stretched out wings. Male characteristic features include a bright red bill with a rounded knob at the base.
The grey teal is a dabbling duck found in open wetlands in Australia and New Zealand.
The falcated duck or falcated teal is a gadwall-sized dabbling duck from the east Palearctic.
Balut is a fertilized developing egg embryo that is boiled and eaten from the shell. It is commonly sold as street food in South China and Southeast Asian countries, notably the Philippines, Cambodia and Vietnam. The term comes from the Filipino language.
The common frog, also known as the European common frog, European common brown frog, European grass frog, European Holarctic true frog, European pond frog or European brown frog, is a semi-aquatic amphibian of the family Ranidae, found throughout much of Europe as far north as Scandinavia and as far east as the Urals, except for most of Iberia, Southern Italy, and the southern Balkans. The farthest west it can be found is Ireland. It is also found in Asia, and eastward to Japan.
Chick culling or unwanted chick killing is the process of separating and killing unwanted chicks for which the intensive animal farming industry has no use. It occurs in all industrialised egg production, whether free range, organic, or battery cage. Worldwide, around 7 billion male chicks are culled each year in the egg industry. Because male chickens do not lay eggs and only those in breeding programmes are required to fertilise eggs, they are considered redundant to the egg-laying industry and are usually killed shortly after being sexed, which occurs just days after they are conceived or after they hatch. Some methods of culling that do not involve anaesthetics include: cervical dislocation, asphyxiation by carbon dioxide, and maceration using a high-speed grinder. Maceration is the primary method in the United States.
Duck plague is a worldwide disease caused by Anatid alphaherpesvirus 1 (AnHV-1) of the family Herpesviridae that causes acute disease with high mortality rates in flocks of ducks, geese, and swans. It is spread both vertically and horizontally—through contaminated water and direct contact. Migratory waterfowl are a major factor in the spread of this disease as they are often asymptomatic carriers of disease. The incubation period is three to seven days. Birds as young as one week old can be infected. DEV is not zoonotic.
