Horned Grebe
The horned grebe or Slavonian grebe (''Podiceps auritus'') is a relatively small waterbird in the family Podicipedidae. There are two known subspecies: ''P. a. auritus'', which breeds in the Palearctic, and ''P. a. cornutus'', which breeds in North America. The Eurasian subspecies is distributed over most of northern Europe and the Palearctic, breeding from Greenland to western China. The North American subspecies spans most of Canada and some of the United States. The species got its name from large patches of yellowish feathers located behind the eyes, called "horns", that the birds can raise and lower at will. Description Horned grebes can be easily recognised by its red-and-black alternate (breeding) plumage, its black-and-white basic (non-breeding) plumage, and its characteristic "horns". It is 31–38 cm long, has a wingspan 55–74 cm wide and weighs 300–570 g. It has a moderately long neck, flat forehead and a rear crown of black feathers. Its beak ...

Cold Regions Science And Technology
Cold is the presence of low temperature, especially in the atmosphere. In common usage, cold is often a subjective perception. A lower bound to temperature is absolute zero, defined as 0.00K on the Kelvin scale, an absolute thermodynamic temperature scale. This corresponds to on the Celsius scale, on the Fahrenheit scale, and on the Rankine scale. Since temperature relates to the thermal energy held by an object or a sample of matter, which is the kinetic energy of the random motion of the particle constituents of matter, an object will have less thermal energy when it is colder and more when it is hotter. If it were possible to cool a system to absolute zero, all motion of the particles in a sample of matter would cease and they would be at complete rest in the classical sense. The object could be described as having zero thermal energy. Microscopically in the description of quantum mechanics, however, matter still has zero-point energy even at absolute zero, because ...

Fairbanks Daily News Miner
The '' Fairbanks Daily News-Miner'' is a morning daily newspaper serving the city of Fairbanks, Alaska, the Fairbanks North Star Borough, the Denali Borough, and the Yukon-Koyukuk Census Area in the U.S. state of Alaska. It is the farthest north daily in the United States, and one of the farthest north in the world. The oldest continuously operating daily in Alaska, by circulation it is the second-largest daily in the state. It was purchased by the Helen E. Snedden Foundation in 2016. The Snedden family were longtime owners of the ''News-Miner'', selling it to a family trust for Dean Singleton and Richard Scudder, founders of the Media News Group in 1992. The ''News-Miner'' was founded as the ''Weekly Fairbanks News'' in 1903 by George M. Hill and assumed the ''News-Miner'' name in 1909, under editor William Fentress Thompson, when Zachary Hickman sold his newspaper, ''The Miner News'', to the ''Fairbanks News''.

Bohemian Waxwing
The Bohemian waxwing (''Bombycilla garrulus'') is a starling-sized passerine bird that breeds in the northern forests of the Palearctic and North America. It has mainly buff-grey plumage, black face markings and a pointed crest. Its wings are patterned with white and bright yellow, and some feather tips have the red waxy appearance that give this species its English name. The three subspecies show only minor differences in appearance. Females are similar to males, although young birds are less well-marked and have few or no waxy wingtips. Although the Bohemian waxwing's range overlaps those of the cedar and Japanese waxwings, it is easily distinguished from them by size and plumage differences. The breeding habitat is coniferous forests, usually near water. The pair build a lined cup-shaped nest in a tree or bush, often close to the trunk. The clutch of 3–7 eggs is incubated by the female alone for 13–14 days to hatching. The chicks are altricial and naked, and are ...

Pectoral Sandpiper
The pectoral sandpiper (''Calidris melanotos'') is a small, migratory wader that breeds in North America and Asia, wintering in South America and Oceania. It eats small invertebrates. Its nest, a hole scraped in the ground and with a thick lining, is deep enough to protect its four eggs from the cool breezes of its breeding grounds. The pectoral sandpiper is long, with a wingspan of . Taxonomy The pectoral sandpiper is sometimes separated with the "stint" sandpipers in ''Erolia''. This may or may not represent a good monophyletic group, depending on the placement of the phylogenetically enigmatic curlew sandpiper (''"C." ferruginea''), the type species of ''Erolia''. In any case, the genus name ''Ereunetes''—formerly used for the western sandpiper (''"C." mauri'') and semipalmated sandpiper (''"C." pusilla''), which are also members of the stint clade—was established before ''Erolia''. "Cox's sandpiper" (''"Calidris"'' × ''paramelanotos'') is a stereotyped hybrid between t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Red-necked Phalarope
The red-necked phalarope (''Phalaropus lobatus''), 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. Taxonomy In 1743 the English naturalist George Edwards included an illustration and a description of the red-necked phalarope in the first volume of his ''A Natural History of Uncommon Birds''. He used the English name "The coot-footed tringa". Edwards based his hand-coloured etching on a specimen that had been collected off the coast of Maryland. When in 1758 the Swedish naturalist Carl Linnaeus updated his ''Systema Naturae'' for the tenth edition, he placed the red-necked phalarope with the phalaropes and sandpipers in the genus ''Tringa''. Linnaeus included a brief description, coined the binomial name ''Tringa lobata'' and cited Edwards' work. The red-necked phalarope is now placed in the g ...

Long-billed Dowitcher
The long-billed dowitcher (''Limnodromus scolopaceus'') is a medium-sized shorebird with a relatively long bill belonging to the sandpiper family, Scolopacidae. In breeding plumage, adults are characterized by a beautiful rufous head and underparts with a darker mottled back and a large white upper rump only seen in flight. They feed in various freshwater habitats with their bill underwater in a "sewing machine" motion and are known to have an exciting mating display where males chase females in flight. The genus, ''Limnodromus'' is Ancient Greek from ''limne'', "marsh" and ''dromos'', "racer". The specific ''scolopaceus'' is New Latin for "snipe-like", from Latin ''scolopax, scolopacis'', a snipe or woodcock. The English name is from Iroquois and was first recorded in 1841. The Long-billed dowitcher is nearly identical in appearance to the Short-billed dowitcher and was only recognized as a separate species in 1950 by Pitelka. Between the two, the best distinguishing field mar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lesser Yellowlegs
The lesser yellowlegs (''Tringa flavipes'') is a medium-sized shorebird. It breeds in the boreal forest region of North America. Taxonomy The lesser yellowlegs was formally described in 1789 by the German naturalist Johann Friedrich Gmelin in his revised and expanded edition of Carl Linnaeus's ''Systema Naturae''. He placed it in the genus '' Scolopax'' and coined the binomial name ''Scolopax flavipes''. Gmelin based his description on the "yellow shanks" seen in the province of New York in autumn that had been described in 1785 by both the English ornithologist John Latham and by the Welsh naturalist Thomas Pennant. The lesser yellowlegs is now placed in the genus ''Tringa'' that was introduced in 1758 by the Swedish naturalist Carl Linnaeus in the tenth edition of his ''Systema Naturae''. The name ''Tringa'' is the New Latin word given to the green sandpiper by the Italian naturalist Ulisse Aldrovandi in 1603 based on Ancient Greek ''trungas'', a thrush-sized, white-rumped, ...

Wilson's Snipe
Wilson's snipe (''Gallinago delicata'') is a small, stocky shorebird. The genus name ''gallinago'' is New Latin for a woodcock or snipe from Latin ''gallina'', "hen" and the suffix ''-ago'', "resembling". The specific ''delicata'' is Latin for "dainty". This species was considered to be a subspecies of the common snipe (''G. gallinago'') until 2003 when it was given its own species status, though not all authorities recognized this immediately. Wilson's snipe differs from the latter species in having a narrower white trailing edge to the wings, and eight pairs of tail feathers instead of the typical seven of the common snipe. Its common name commemorates the American ornithologist Alexander Wilson. Description Adults are in length with a wingspan. Weight ranges from . They have short greenish-grey legs and a very long straight dark bill. The body is mottled brown on top and pale underneath. They have a dark stripe through the eye, with light stripes above and below it. The wi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bonaparte's Gull
Bonaparte's gull (''Chroicocephalus philadelphia'') is a member of the gull family Laridae found mainly in northern North America. At in length, it is one of the smallest species of gull. Its plumage is mainly white with grey upperparts. During breeding season, Bonaparte's gull gains a slate-grey hood. The sexes are similar in appearance. Taxonomy and etymology When George Ord first described Bonaparte's gull in 1815, he gave it the scientific name ''Sterna philadelphia'', assigning it to the genus now used for medium-sized terns. Most later taxonomists assigned it to the genus ''Larus'', a longtime catch-all for most of the gull species. However, in 1858, George Newbold Lawrence moved the species to the genus ''Chroicocephalus'', and some taxonomists followed suit. Recent molecular DNA studies have shown that this species fits neatly into a clade with other "masked gulls", and that it and the slender-billed gull are each other's closest relatives and are basal to the rest of ...
