The ring-necked duck (Aythya collaris) is a diving duck from North America commonly found in freshwater ponds and lakes. [3] The scientific name is derived from Greek aithuia, an unidentified seabird mentioned by authors including Hesychius and Aristotle, and Latin collaris, "of the neck" from collum, "neck". [4]
Ring-necked ducks are small to medium-sized diving ducks with the following length, weight, and wingspan measurements: [5]
The adult male is similar in color pattern to the Eurasian tufted duck, its relative. Males are a little bit bigger than the female. It has two white rings surrounding its gray bill, a shiny black angular head, black back, white line on the wings, a white breast and yellow eyes. The adult female has a grayish brown angular head and body with a dark brown back, a dark bill with a more subtle light band than the male, grayish-blue feet and brown eyes with white rings surrounding them. Females also make a noise like trrr. The cinnamon neck ring is usually difficult to observe, which is why the bird is sometimes referred to as a "ringbill". [6] [7] [8]
Their breeding habitat is wooded lakes or ponds in the northern United States and Canada. The main breeding area is Northwest boreal forest territories. Their breeding habits also take place in the eastern boreal region of Canada but no where near the same amount in the northwestern region. In the winter months they are usually found in southern North America in lakes, ponds, rivers or bays. Ring-necked duck pairs start during spring migration. Unpaired ducks showing up on breeding grounds will most likely end up being non-breeders. The pairs stay together only for reproduction, after that, they separate. The nest is bowl-shaped, built on water in dense emergent vegetation with sedges and woody plants. The female lays one egg per day until 8 to 10 eggs are laid. They are incubated 25–29 days and the female may remain with the young until they are able to fly. [6] [7] [8]
These birds are omnivores and feed mainly by diving or dabbling at the surface. Ducklings are dependent on animal matter such as insects, earthworms, leeches, midges and snails. As they mature they tend change their diet to submerged plants such as pondweed and coontail, and emergents such as annual wild rice and snails. [6] [7] [8]
This strong migrant is a rare but regular vagrant to western Europe. In Britain, occasional small flocks occur, including five at Loch Leven, Scotland in September 2003 [9] and four at Standlake in Oxfordshire in April 2015. [10] In Ireland one or two individuals can be seen at any time of year. Vagrant individuals also occur each year in Central America as far south as Costa Rica between October/November and May/June. [11] They have also been reported in small numbers in Suriname and French Guiana, in northern South America. [12]
The gadwall is a common and widespread dabbling duck in the family Anatidae.
The American wigeon, also known as the baldpate, is a species of dabbling duck found in North America. Formerly assigned to Anas, this species is classified with the other wigeons in the dabbling duck genus Mareca. It is the New World counterpart of the Eurasian wigeon.
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 canvasback is a species of diving duck, the largest found in North America.
The common pochard 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 ferina, "wild game", from ferus, "wild".
The tufted duck or tufted pochard is a small diving duck with a population of close to one million birds, found in northern Eurasia. The scientific name is derived from Ancient Greek aithuia, an unidentified seabird mentioned by authors including Hesychius and Aristotle, and Latinfuligo "soot" and gula "throat".
The hooded merganser is a species of fish-eating duck in the subfamily Anatinae. It is the only extant species in the genus Lophodytes. The genus name derives from the Greek language: lophos meaning 'crest', and dutes meaning 'diver'. The bird is striking in appearance; both sexes have crests that they can raise or lower, and the breeding plumage of the male is handsomely patterned and coloured. The hooded merganser has a sawbill but is not classified as a typical merganser.
The red-breasted merganser is a duck species that is native to much of the Northern Hemisphere. The red breast that gives the species its common name is only displayed by males in breeding plumage. Individuals fly rapidly, and feed by diving from the surface to pursue aquatic animals underwater, using serrated bills to capture slippery fish. They migrate each year from breeding sites on lakes and rivers to their mostly coastal wintering areas, making them the only species in the genus Mergus to frequent saltwater. They form flocks outside of breeding season that are usually small but can reach 100 individuals. The worldwide population of this species is stable, though it is threatened in some areas by habitat loss and other factors.
The common goldeneye or simply goldeneye is a medium-sized sea duck of the genus Bucephala, the goldeneyes. Its closest relative is the similar Barrow's goldeneye. The genus name is derived from the Ancient Greek boukephalos, a reference to the bulbous head shape of the bufflehead. The species name is derived from the Latin clangere.
The ruddy duck is a duck from North America and one of the stiff-tailed ducks. The genus name is derived from Ancient Greek oxus, "sharp", and oura, "tail", and jamaicensis is "from Jamaica".
Barrow's goldeneye is a medium-sized sea duck of the genus Bucephala, the goldeneyes. This bird was named after Sir John Barrow. The genus name is derived from Ancient Greek boukephalos, "bullheaded", from bous, "bull" and kephale, "head", a reference to the bulbous head shape of the bufflehead. The species name islandica means Iceland.
The bufflehead is a small sea duck of the genus Bucephala, the goldeneyes. This species was first described by Carl Linnaeus in his landmark 1758 10th edition of Systema Naturae as Anas albeola.
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 lesser scaup is a small North American diving duck that migrates south as far as Central America in winter. It is colloquially known as the little bluebill or broadbill because of its distinctive blue bill. The origin of the name scaup may stem from the bird's preference for feeding on scalp—the Scottish word for clams, oysters, and mussels; however, some credit it to the female's discordant scaup call as the name's source. It is apparently a very close relative of the Holarctic greater scaup or "bluebill", with which it forms a superspecies. The scientific name is derived from Ancient Greek aithuia an unidentified seabird mentioned by authors including Hesychius and Aristotle, and Latin, affinis "related to", from its resemblance to the greater scaup.
The ferruginous duck, also known as ferruginous pochard, common white-eye or white-eyed pochard, is a medium-sized diving duck from Eurosiberia. The scientific name is derived from Greek aithuia an unidentified seabird mentioned by authors including Hesychius and Aristotle, and nyrok, the Russian name for a duck.
The Philadelphia vireo is a small North American songbird in the vireo family (Vireonidae). "Vireo" is a Latin word referring to a green migratory bird, perhaps the female golden oriole, possibly the European greenfinch. The specific philadelphicus is for the city of Philadelphia.
The bay-breasted warbler is a small species of songbird in the New World warbler family, Parulidae. It is one of thirty-four species in the diverse genus Setophaga. Like all songbirds, or passerines, the species is classified in the order Passeriformes.
The Tennessee warbler is a New World warbler that breeds in eastern North America and winters in southern Central America, the Caribbean, and northern South America. The specific name peregrina is from Latin peregrinus "wanderer".
Aythya is a genus of diving ducks. It has twelve described species. The name Aythya comes from the Ancient Greek word αυθυια, which may have referred to a sea-dwelling duck or an auklet.
Baer's pochard is a diving duck found in eastern Asia. It is a resident bird in North and Central China, formerly bred in southeast Russia and Northeast China, migrating in winter to southern China, Vietnam, Japan, and India. Baer's pochard is a monotypic species. The holotype was collected in middle Amur.
