Siberian Jay (Perisoreus Infaustus) (13667845783)
The Siberian jay (''Perisoreus infaustus'') is a small jay with a widespread distribution within the coniferous forests in North Eurasia. It has grey-brown plumage with a darker brown crown and a paler throat. It is rusty-red in a panel near the wing-bend, on the undertail coverts and on the sides of the tail. The sexes are similar. Although its habitat is being fragmented, it is a common bird with a very wide range so the International Union for Conservation of Nature has assessed its conservation status as being of "least concern". Taxonomy and systematics The Siberian jay was formally described by the Swedish naturalist Carl Linnaeus in 1758 in the tenth edition of his ''Systema Naturae'' under the binomial name ''Corvus infaustus''. Linnaeus specified the location as "Europae alpinis sylvis" but the type location was restricted to Sweden by Ernst Hartert in 1903. The specific epithet ''infaustus'' is Latin meaning "unlucky" or "unfortunate" as Siberian jays were formerly con ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

The municipality has a population of () and covers an area of of which is water. The population density is . Kittilä is famous for being the location of the lowest recorded temperature in Finnish history: , measured in January 1999 in Pokka. The "midnight sun" is above the horizon from 29 May to 16 July, and the period with continuous daylight lasts a bit longer, polar night from 14 December to 29 December. Climate Kittilä has a subarctic climate (Köppen climate classification, Dfc) as a result of its northerly location and being far inland, which renders strong seasonal shifts.

Petr Sushkin
Petr Petrovich Sushkin (; 27 January 1868 – 17 September 1928) was a Russian and Soviet based ornithologist who specialised on comparative anatomy, and evolution of birds, particularly of the birds of prey. Sushkin was born in Tula, Russia, in a merchant family. He studied at the Tula Classical Gymnasium (1877-1885) graduating with a silver medal before going on to Moscow University in 1885. He graduated in 1890 and joined the staff of the Leningrad Zoological Museum in 1898. He studied ornithology under Mikhail Menzbier and his dissertation in 1897 was on the morphology of the skeleton of birds, specifically of the kestrel. He conducted surveys in the Ufa province in 1891 and Kazakhstan in 1898. His studies on the birds of southeastern Russia, Siberia and the Altai Mountains were published in several monographs. Sushkin visited European museums from 1899 to 1900 and worked on his doctoral dissertation on the birds of prey. He became a professor at Moscow University and in 1909 ...

Corvidae
Corvidae is a Cosmopolitan distribution, cosmopolitan Family (biology), family of Songbird, oscine passerine birds that contains the crows, ravens, Rook (bird), rooks, magpies, jackdaws, jays, treepies, choughs, and Nutcracker (bird), nutcrackers. In Colloquialism, colloquial English, they are known as the crow family or corvids. Currently, 139 species are included in this family. The genus ''Corvus'' containing 50 species makes up over a third of the entire family. Corvids (ravens) are the largest passerines. Corvids display remarkable Animal cognition, intelligence for animals of their size, and are among the most Bird intelligence, intelligent birds thus far studied. Specifically, members of the family have demonstrated self-awareness in mirror tests (Eurasian magpies) and Tool use by animals, tool-making ability (e.g. crows and rooks), skills which until recently were thought to be possessed only by humans and a few other mammals.

Oesophagus
The esophagus (American English), oesophagus (British English), or œsophagus ( archaic spelling) ( see spelling difference) all ; : ((o)e)(œ)sophagi or ((o)e)(œ)sophaguses), colloquially known also as the food pipe, food tube, or gullet, is an organ in vertebrates through which food passes, aided by peristaltic contractions, from the pharynx to the stomach. The esophagus is a fibromuscular tube, about long in adults, that travels behind the trachea and heart, passes through the diaphragm, and empties into the uppermost region of the stomach. During swallowing, the epiglottis tilts backwards to prevent food from going down the larynx and lungs. The word ''esophagus'' is from Ancient Greek οἰσοφάγος (oisophágos), from οἴσω (oísō), future form of φέρω (phérō, "I carry") + ἔφαγον (éphagon, "I ate"). The wall of the esophagus from the lumen outwards consists of mucosa, submucosa (connective tissue), layers of muscle fibers between lay ...

Clutch (eggs)
A clutch of eggs is the group of eggs produced by birds, amphibians, or reptiles, often at a single time, particularly those laid in a nest. In birds, destruction of a clutch by predators (or removal by humans, for example the California condor breeding program) results in ''double-clutching''. The technique is used to double the production of a species' eggs, in the California condor case, specifically to increase population size. Size Clutch size differs greatly between species, sometimes even within the same genus. It may also differ within the same species due to many factors including habitat, health, nutrition, predation pressures, and time of year. Clutch size variation can also reflect variation in optimal reproduction effort. In birds, clutch size can vary within a species due to various features (age and health of laying female, ability of male to supply food, and abundance of prey), while some species are determinant layers, laying a species-specific number of egg ...

Monogamous Pairing In Animals
Some animal species have a monogamous mating system, in which pairs bond to raise offspring. This is associated, usually implicitly, with sexual monogamy. Monogamous mating Monogamy is defined as a pair bond between two adult animals of the same species. This pair may cohabitate in an area or territory for some duration of time, and in some cases may copulate and reproduce with only each other. Monogamy may either be short-term, lasting one to a few seasons or long-term, lasting many seasons and in extreme cases, life-long. Monogamy can be partitioned into two categories, social monogamy and genetic monogamy which may occur together in some combination, or completely independently of one another.Ophir, Alexander G., Phelps, Steven M., Sorin, Anna Bess & O. Wolff, J. (2008)Social but not genetic monogamy is associated with greater breeding success in prairie voles/ref> As an example, in the cichlid species '' Variabilichromis moorii'', a monogamous pair will care for eggs and y ...

Perisoreus Infaustus MWNH 1368
The genus ''Perisoreus'' is a very small genus of jays from the Boreal regions of North America and Eurasia from Scandinavia to the Asian seaboard. An isolated species also occurs in north-western Sichuan of China. They belong to the Passerine order of birds in the family Corvidae. Species of ''Perisoreus'' jays are most closely related to the genus ''Cyanopica''. The genus was introduced by the French zoologist Charles Lucien Bonaparte in 1831. The type species was subsequently designated as the Canada jay. The name of the genus may come from the Ancient Greek ''perisōreuō'' "to heap up" or "bury beneath". Alternatively it may be from the Latin ''peri-'' "very" or "exceedingly" and ''sorix'', a bird of augury Augury was a Greco- Roman religious practice of observing the behavior of birds, to receive omens. When the individual, known as the augur, read these signs, it was referred to as "taking the auspices". "Auspices" () means "looking at birds". ... dedicated to Satur ...

Plumage
Plumage () is a layer of feathers that covers a bird and the pattern, colour, and arrangement of those feathers. The pattern and colours of plumage differ between species and subspecies and may vary with age classes. Within species, there can be different colour morph (zoology), morphs. The placement of feathers on a bird is not haphazard but rather emerges in organized, overlapping rows and groups, and these are known by standardized names. Most birds moult twice a year, resulting in a breeding or ''nuptial plumage'' and a ''basic plumage''. Many ducks and some other species such as the red junglefowl have males wearing a bright nuptial plumage while breeding and a drab ''eclipse plumage'' for some months afterward. The painted bunting's juveniles have two inserted moults in their first autumn, each yielding plumage like an adult female. The first starts a few days after fledging replacing the ''juvenile plumage'' with an ''auxiliary formative plumage''; the second a month o ...
