50-673: The Rote Liste , full name Rote Liste der bedrohten Nutztierrassen im Bundesgebiet , is a red list of threatened breeds of domestic animal published annually by the Gesellschaft zur Erhaltung alter und gefährdeter Haustierrassen , the German national association for the conservation of historic and endangered domestic animal breeds. The GEH was founded in Witzenhausen , in Hesse , central Germany, in 1981. In 1987 it established

100-449: A rare breed is a breed of poultry or livestock that has a very small breeding population, usually from a few hundred to a few thousand. Because of their small numbers, rare breeds may have a threatened conservation status , and they may be protected under regional laws. Many countries have organizations devoted to the protection and promotion of rare breeds, for which they each have their own definition. In botany and horticulture ,

150-786: A Muscovy duck is also much heavier than most other domestic ducks, which makes it ideal for the dinner table. Domesticated Muscovy ducks, like those pictured, often have plumage features differing from other wild birds. White breeds are preferred for meat production, as darker ones can have much melanin in the skin, which some people find unappealing. The Muscovy duck can be crossed with mallards in captivity to produce hybrids known as mulards (" mule ducks") because they are sterile . Muscovy drakes are commercially crossed with mallard-derived hens either naturally or by artificial insemination . The 40–60% of eggs that are fertile result in birds raised only for their meat or for production of foie gras : they grow fast like mallard-derived breeds, but to

200-467: A clutch of 8–16 white eggs, usually in a tree hole or hollow, which are incubated for 35 days. The sitting hen will leave the nest once a day from 20 minutes to one and a half hours, and will then defecate, drink water, eat and sometimes bathe. Once the eggs begin to hatch, it may take 24 hours for all the chicks to break through their shells. When feral chicks are born, they usually stay with their mother for about 10–12 weeks. Their bodies cannot produce all

250-575: A dark head and blue eyes, others a light brown crown and dark markings on their nape. They are agile and speedy precocial birds. The drake has a low breathy call, and the hen a quiet trilling coo. [REDACTED] The karyotype of the Muscovy duck is 2n=80, consisting of three pairs of macrochromosomes , 36 pairs of microchromosomes , and a pair of sex chromosomes . The two largest macrochromosome pairs are submetacentric , while all other chromosomes are acrocentric or probably telocentric for

300-537: A lack of profitability or competitiveness, the intensification of production systems, the effects of diseases and disease management and loss of pastures or other elements of the production environment. In postwar Britain , for example, the introduction of the Poland China pig and the Texel sheep affected populations of historic breeds, which were seen as less profitable for farmers. Several organizations –

350-536: A large size like Muscovy ducks. Conversely, though crossing mallard-derived drakes with Muscovy hens is possible, the offspring are neither desirable for meat nor for egg production. In addition, Muscovy ducks are reportedly crossbred in Israel with mallards to produce kosher duck products. The kashrut status of the Muscovy duck has been a matter of rabbinic discussion for over 150 years. A study examining birds in northwestern Colombia for blood parasites found

400-456: A naked and carunculated face"), and his primary reference is his earlier work Fauna Svecica . But Linnaeus refers also to older sources, wherein much information on the origin of the common name is found. Conrad Gessner is given by Linnaeus as a source, but the Historia animalium mentions the Muscovy duck only in passing. Ulisse Aldrovandi discusses the species in detail, referring to

450-440: A nude black-and-red or all-red face; the drake also has pronounced caruncles at the base of the bill and a low erectile crest of feathers. C. moschata ducklings are mostly yellow with buff-brown markings on the tail and wings. For a while after hatching, juveniles lack the distinctive wattles associated with adult individuals, and resemble the offspring of various other ducks, such as mallards . Some domesticated ducklings have

500-720: A poultry breed "Rare" when it does not have its own breed club . These "Rare Breeds" are catered by the Rare Poultry Society (RPS). The RPS does not look after breeds that count few individuals but have their own breed club. The British Rabbit Council (BRC) notes in its breed standards those rabbit breeds that have been recognized by the affiliated Rare Varieties Rabbit Club, of which there are currently  26 breeds . Major factors causing breeds to become rare are reported to include increased use of exotic breeds, weak policies and institutions in animal genetic resources management , neglect of certain breeds because of

550-1343: A separate list of the historic poultry breeds and colour varieties that were raised in Germany before 1930. The same levels of conservation risk are assigned as in the main red list.

600-445: A significant extent. Alternatively—just as in the " turkey " (which is also from North America, not Turkey) and the " guineafowl " (which are not limited to Guinea )—"Muscovy" might be simply a generic term for an exotic place, in reference to the singular appearance of these birds. This is evidenced by other names suggesting the species came from lands where it is not actually native, but from where much "outlandish" produce

650-475: A wide, flat tail. In the domestic drake (male), length is about 86 cm (34 in) and weight is 4.6–6.8 kg (10–15 lb), while the domestic hen (female) is much smaller, at 64 cm (25 in) in length and 2.7–3.6 kg (6.0–7.9 lb) in weight. Large domesticated males often weigh up to 7 kg (15 lb), and large domesticated females up to 4 kg (8.8 lb). The true wild Muscovy duck, from which all domestic Muscovies originated,

700-907: Is a duck native to the Americas , from the Rio Grande Valley of Texas and Mexico south to Argentina and Uruguay . Feral Muscovy ducks are found in New Zealand , Australia , and in Central and Eastern Europe . Small wild and feral breeding populations have also 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 . It

750-416: Is a large duck, with the males about 76 cm (30 in) long, and weighing up to 7 kg (15 lb). Females are noticeably smaller, and only grow to 3 kg (6.6 lb), roughly half the males' size. The bird is predominantly black and white, with the back feathers being iridescent and glossy in males, while the females are more drab. The amount of white on the neck and head is variable, as well as

800-640: Is an old name for the region of Russia surrounding Moscow, but these ducks are neither native there nor were introduced there before they became known in Western Europe. It is not quite clear how the term came about; it very likely originated between 1550 and 1600, but did not become widespread until somewhat later. In one suggestion, it has been claimed that the Company of Merchant Adventurers to New Lands traded these ducks to Europe occasionally after 1550; this chartered company became eventually known as

850-406: Is blackish, with large white wing patches. Length can range from 66 to 84 cm (26 to 33 in), wingspan from 137 to 152 cm (54 to 60 in) and weight from 1.1 to 4.1 kg (2.4 to 9.0 lb). On the head, the wild male has a short crest on the nape. The bill is black with a speckling of pale pink. A blackish or dark red knob can be seen at the bill base, which is similar in colour to

900-535: Is calculated using a formula that takes into account five criteria: the number of breeding animals or breeding females; the percentage of pure-bred matings; the five-year trend in breed numbers; the number of breeders or herds; and the interval between generations of the animal. The GEH also publishes, in conjunction with the Bund Deutscher Rassegeflügelzüchter  [ de ] , the German national association of poultry breeders,

950-441: Is in response to local efforts to cull the eggs, which has led to an atypical distribution of males and females, as well as young and mature birds. For the first few weeks of their lives, Muscovy chicks feed on grains, corn, grass, insects, and almost anything that moves. Their mother instructs them at an early age how to feed. Feral Muscovy ducks can breed near urban and suburban lakes and on farms, nesting in tree cavities or on

1000-894: Is maintained in a cryoconserved form. In 2009, The Livestock Conservancy launched an online classified advertising service for promoting rare breeds. It allows the general public to "browse listings of rare breed livestock and poultry for sale, rare breed products such as meats and wools and other items that help secure the future of rare breeds". Beyond the concerns of conservation organisations, there are other reasons for individuals or groups to keep rare breed animals. Rare breeds can be popular with hobby farmers , as they often require less intensive management. Some rare breeds are kept by tourist attractions for their value in attracting visitors. Some farmers also prefer to sell meat from rare breeds, as they believe such breeds offer higher quality produce. Muscovy Duck Anas moschata Linnaeus, 1758 The Muscovy duck ( Cairina moschata )

1050-446: Is predictably similar to their genitors, and that this similarity is genetically based. This biological definition is useful for conservation , which treats breeds as reliable sources of genetic diversity . Conservation organisations each have their own definition of what constitutes a rare breed. The Rare Breeds Survival Trust (RBST) and The Livestock Conservancy (TLC) both divide rare breeds into five categories, "critical" being

1100-644: Is the term used for C. moschata in a culinary context. The domestic subspecies, Cairina moschata domestica , is commonly known in Spanish as the pato criollo . They have been bred since pre-Columbian times by Native Americans and are heavier and less able to fly long distances than the wild subspecies. Their plumage color is also more variable. Other names for the domestic breed in Spanish are pato casero ("household duck") and pato mudo ("mute duck"). All Muscovy ducks have long claws on their feet and

1150-501: The Australian species Biziura lobata . The currently assigned genus name Cairina , meanwhile, traces its origin to Aldrovandi and the mistaken belief that the birds came from Egypt : translated, the current scientific name of the Muscovy duck means "the musky one from Cairo". In some regions the name "Barbary duck" is used for domestic and "Muscovy duck" for wild birds; in other places, "Barbary duck" refers specifically to

1200-663: The Fauna Svecica and again in the travelogue of this 1746 Västergötland excursion. Similarly, the Russian name of this species, muskusnaya utka (Мускусная утка), means "musk duck" – without any reference to Moscow – as do the Bokmål and Danish moskusand , Dutch muskuseend , Finnish myskisorsa , French canard musqué , German Moschusente , Italian anatra muschiata , Spanish pato almizclado and Swedish myskand . In English, however, musk duck refers to

1250-632: The Food and Agriculture Organization ( United Nations ), The Livestock Conservancy , the Rare Breeds Survival Trust (UK), Rare Breeds Canada , the SVF Foundation (US) – promote conservation of rare livestock and poultry breeds for their unique traits, which can contribute to general biodiversity and cultural heritage. Animal Husbandry can be important to livestock production in harsh environments and may contribute to

1300-458: The Santa Maria , they then sailed back to Europe by the 16th century. The Muscovy duck has been domesticated for centuries, and is widely traded as "Barbary duck". Muscovy breeds are popular because they have stronger-tasting meat—sometimes compared to roast beef —than the usual domestic ducks , which are descendants of the mallard ( Anas platyrhynchos ). The meat is lean when compared to

1350-623: The Walsall Arboretum . There has been a small population in the Pavilion Gardens public park in Buxton , Derbyshire for many years. In the U.S., Muscovy ducks are considered a non-native species. An owner may raise them for food production only (not for hunting). Similarly, if the ducks have no owner, 50CFR Part 21 (Migratory Bird Permits) allows the removal or destruction of the ducks, their eggs and their nests anywhere in

1400-449: The roots , stems , leaves , and seeds of aquatic plants and grasses , as well as terrestrial plants, including agricultural crops ) obtained by grazing or dabbling in shallow water, and small fish , amphibians , reptiles , crustaceans , spiders , insects, millipedes , and worms . This is an aggressive duck; males often fight over food, territory or mates. The females fight with each other less often. Some adults will peck at

1450-407: The shelduck subfamily Tadorninae . In addition, the other species of Cairina , the rare white-winged duck ( C. scutulata ), seems to belong to a distinct genus ( Asarcornis ). This non-migratory species normally inhabits forested swamps , lakes , streams and nearby grassland and farm crops, and often roosts in trees at night. The Muscovy duck's diet consists of plant material (such as

1500-535: The " Muscovy Company " or "Muscovite Company" so the ducks might thus have come to be called "Muscovite ducks" or "Muscovy ducks" in keeping with the common practice of attaching the importer's name to the products they sold. But while the Muscovite Company initiated vigorous trade with Russia, they hardly, if at all, traded produce from the Americas; thus, they are unlikely to have traded C. moschata to

1550-463: The U.S. prohibiting trade of Muscovy ducks, Fish and Wildlife Services intend to revise the regulations. They are not currently implementing them, though release of Muscovy ducks to the wild outside their natural range is prohibited. Muscovy ducks had been domesticated by various Native American cultures in the Americas when Columbus arrived in the Bahamas. A few were brought onto Columbus' ship

1600-546: The United States outside of Hidalgo , Starr and Zapata Counties in Texas, where they are considered indigenous. The population in southern Florida is considered, with numbers in the several thousands, to be established enough to be considered "countable" for bird watchers. Legal methods to restrict breeding include not feeding these ducks, deterring them with noise or chasing them away. Although legislation passed in

1650-491: The adaptation of livestock populations to challenges such as shifts in disease epidemiology, climate or market demands. Conservation activities may include in situ conservation programmes supporting the maintenance of breeds in their normal production environments (i.e. on farms, ranches or in pastoralist herds or flocks) and ex situ conservation programmes in which animals are kept at sites such as zoos or special conservation farms or genetic material (e.g. semen or embryos)

1700-590: The average European of those times, would be corrupted into something more familiar. Likewise, the Miskito Indians of the Miskito Coast in Nicaragua and Honduras heavily relied on it as a domestic species, and the ducks as well may have been named after this region. Linnaeus’ description of Anas moschata only consists of a curt but entirely unequivocal [Anas] facie nuda papillosa ("A duck with

1750-470: The bare skin of the face. The eyes are yellowish-brown. The legs and webbed feet are blackish. The wild female is similar in plumage, but much smaller, with a feathered face and lacking the prominent knob. The juvenile is duller overall, with little or no white on the upperwing. Domesticated birds may look similar; most are dark brown or black mixed with white, particularly on the head. Other colors, such as lavender or all-white, are also seen. Both sexes have

1800-495: The bill, which can be yellow, pink, black, or any mixture of these colors. It may have white patches or bars on the wings, which become more noticeable during flight. Both sexes have pink or red wattles around the bill, those of the male being larger and more brightly colored. Although the Muscovy duck is a tropical bird, it adapts well to cooler climates, thriving in weather as cold as −12 °C (10 °F) and able to survive even colder conditions. In general, Barbary duck

1850-479: The criteria on which the Rote Liste is based. The list is published annually, and attributes one of four categories of conservation risk to domestic breeds of cattle, dogs, goats, horses, pigs, rabbits and sheep, of chickens, ducks, geese and turkeys, and of bees; listing of domestic pigeon breeds is in preparation. Some breeds from outside Germany are listed separately. The four levels of risk are: The risk level

1900-404: The dressed carcass, while "Muscovy duck" applies to living C. moschata , regardless of whether they are wild or domestic. In general, "Barbary duck" is the usual term for C. moschata in a culinary context. The species was first scientifically described by Carl Linnaeus in his 1758 edition of Systema Naturae as Anas moschata , literally meaning " musk duck". It was later transferred to

1950-595: The ducklings if they are eating at the same food source. The Muscovy duck has benefited from nest boxes in Mexico , but is somewhat uncommon in much of the eastern part of its range due to excessive hunting. It is not considered a globally threatened species by the IUCN , however, as it is widely distributed. This species, like the mallard , does not form stable pairs. They will mate on land or in water. Domestic Muscovy ducks can breed up to three times each year. The hen lays

2000-514: The fatty meat of mallard-derived ducks, its leanness and tenderness being often compared to veal . Muscovy ducks are also less noisy, and sometimes marketed as a " quackless " duck; even though they are not completely silent, they do not actually quack (except in cases of extreme stress). Many backyard duck owners report that Muscovy ducks have more personality than mallard-derived ducks, often comparing them to dogs for their tameness and willingness to approach owners for food or stroking. The carcass of

2050-428: The genus Cairina , making its current binomial name Cairina moschata . The Muscovy duck was formerly placed into the paraphyletic " perching duck " assemblage, but subsequently moved to the dabbling duck subfamily (Anatinae). Analysis of the mtDNA sequences of the cytochrome b and NADH dehydrogenase subunit 2 genes , however, indicates that it might be closer to the genus Aix and better placed in

2100-536: The ground, under shrubs in yards, on apartment balconies, or under roof overhangs. Some feral populations, such as that in southern Florida , have a reputation of becoming pests on occasion. At night they often sleep at water, if there is a water source available, to flee quickly from predators if awakened. Small populations of Muscovy ducks can also be found in Ely, Cambridgeshire , Calstock, Cornwall , and Lincoln, Lincolnshire , U.K. Muscovy ducks have also been spotted in

2150-510: The heat they need, especially in temperate regions, so they will stay close to the mother, especially at night. Often, the drake will stay in close contact with the brood for several weeks. The male will walk with the young during their normal travels in search for food, providing protection. Anecdotal evidence from East Anglia , U.K. suggests that, in response to different environmental conditions, other adults assist in protecting chicks and providing warmth at night. It has been suggested that this

2200-480: The list) refer to the very same species. Finally, John Ray attempts to clear up the confusion by providing an alternative explanation for the name's etymology : In English, it is called The Muscovy-Duck , though this is not transferred from Muscovia [the Neo-Latin name of Muscovy], but from the rather strong musk odour it exudes. Linnaeus came to witness the birds' " gamey " aroma first-hand, as he attests in

2250-441: The parallel to rare animal breeds are heirloom plants , which are rare cultivars . There are several definitions of "breed" and "rare breed". Breeds may be defined as a group of animals that share visible characteristics, such as Pinto horses , which are all spotted. A stricter definition insists that breeds are "consistent and predictable genetic entities", which means that individuals from that breed will produce offspring that

2300-536: The rarest. TLC places a livestock breed under "critical" status when it has "fewer than 200 annual registrations in the United States and estimated global population less than 2,000". The RBST determines the status of a breed by the number of its breeding females in the United Kingdom . For horses and sheep, fewer than 300 is considered "critical", whereas goats and pigs must have fewer than 100 to join that category. The Poultry Club of Great Britain considers

2350-462: The smallest microchromosomes. The submetacentric chromosomes and the Z (female) chromosome show rather little constitutive heterochromatin (C bands), while the W chromosomes are at least two-thirds heterochromatin. Male Muscovy ducks have helical penises that become erect to 19 cm (7 in) in 0.3 s . Females have vaginas that coil in the opposite direction that appear to have evolved to limit forced copulation by males. " Muscovy "

2400-495: The species is tied to some more or less nondescript "exotic" locality – "Libya" could still refer to any place in Northern Africa at that time – where it did not natively occur. Francis Willughby discusses "The Muscovy duck" as anas moschata and expresses his belief that Aldrovandi's and Gessner's anas cairina , anas indica and anas libyca (which he calls "The Guiny duck", adding another mistaken place of origin to

2450-484: The wild birds and its domestic breeds variously as anas cairina , anas indica or anas libyca – "duck from Cairo ", "Indian duck" (in reference to the West Indies ) or " Libyan duck". But his anas indica (based, like Gessner's brief discussion, ultimately on the reports of Christopher Columbus 's travels) also seems to have included another species , perhaps a whistling-duck ( Dendrocygna ). Already however

2500-514: Was imported at that time (see below). Yet another view—not incompatible with either of those discussed above—connects the species with the Muisca , a Native American nation in today's Colombia. The duck is native to these lands also, and it is likely that it was kept by the Muisca as a domestic animal to some extent. It is conceivable that a term like "Muisca duck", hard to comprehend for
