Greater Spotted Woodpecker
The great spotted woodpecker (''Dendrocopos major'') is a medium-sized woodpecker with pied black and white plumage and a red patch on the lower belly. Males and young birds also have red markings on the neck or head. This species is found across the Palearctic including parts of North Africa. Across most of its range it is resident, but in the north some will migrate if the conifer cone crop fails. Some individuals have a tendency to wander, leading to the recent recolonisation of Ireland and to vagrancy to North America. Great spotted woodpeckers chisel into trees to find food or excavate nest holes, and also drum for contact and territorial advertisement; like other woodpeckers, they have anatomical adaptations to manage the physical stresses from the hammering action. This species is similar to the Syrian woodpecker. This woodpecker occurs in all types of woodlands and eats a variety of foods, being capable of extracting seeds from pine cones, insect larvae from inside trees ...

Wryneck
The wrynecks (genus ''Jynx'') are a small but distinctive group of small Old World woodpeckers. ''Jynx'' is from the Ancient Greek ''iunx'', the Eurasian wryneck. These birds get their English name from their ability to turn their heads almost 180°. When disturbed at the nest, they use this snake-like head twisting and hissing as a threat display. It has occasionally been called "snake-bird" for that reason. Like the true woodpeckers, wrynecks have large heads, long tongues, which they use to extract their insect prey, and zygodactyl feet, with two toes pointing forward and two backwards,but they lack the stiff tail feathers that the true woodpeckers use when climbing trees, so they are more likely than their relatives to perch on a branch rather than an upright trunk. Wryneck's (Jynginae) sexes are similar. Their bills are shorter and less dagger-like than in the true woodpeckers, but their chief prey is ants and other insects, which they find in decaying wood or almost b ...

Cline (biology)
In biology, a cline (from the Greek κλίνειν ''klinein'', meaning "to lean") is a measurable gradient in a single character (or biological trait) of a species across its geographical range. First coined by Julian Huxley in 1938, the "character" of the cline referred to is usually genetic (e.g. allele frequency, blood type), or phenotypic (e.g. body size, skin pigmentation). Clines can show smooth, continuous gradation in a character, or they may show more abrupt changes in the trait from one geographic region to the next. A cline refers to a spatial gradient in a specific, singular trait, rather than a collection of traits; a single population can therefore have as many clines as it has traits, at least in principle. Additionally, Huxley recognised that these multiple independent clines may not act in concordance with each other. For example, it has been observed that in Australia, birds generally become smaller the further towards the north of the country they are found ...

Latin
Latin (, or , ) is a classical language belonging to the Italic branch of the Indo-European languages. Latin was originally a dialect spoken in the lower Tiber area (then known as Latium) around present-day Rome, but through the power of the Roman Republic it became the dominant language in the Italian region and subsequently throughout the Roman Empire. Even after the fall of Western Rome, Latin remained the common language of international communication, science, scholarship and academia in Europe until well into the 18th century, when other regional vernaculars (including its own descendants, the Romance languages) supplanted it in common academic and political usage, and it eventually became a dead language in the modern linguistic definition. Latin is a highly inflected language, with three distinct genders (masculine, feminine, and neuter), six or seven noun cases (nominative, accusative, genitive, dative, ablative, and vocative), five declensions, four verb conjuga ...

Ancient Greek
Ancient Greek includes the forms of the Greek language used in ancient Greece and the ancient world from around 1500 BC to 300 BC. It is often roughly divided into the following periods: Mycenaean Greek (), Dark Ages (), the Archaic period (), and the Classical period (). Ancient Greek was the language of Homer and of fifth-century Athenian historians, playwrights, and philosophers. It has contributed many words to English vocabulary and has been a standard subject of study in educational institutions of the Western world since the Renaissance. This article primarily contains information about the Epic and Classical periods of the language. From the Hellenistic period (), Ancient Greek was followed by Koine Greek, which is regarded as a separate historical stage, although its earliest form closely resembles Attic Greek and its latest form approaches Medieval Greek. There were several regional dialects of Ancient Greek, of which Attic Greek developed into Koine. Dia ...

Carl Ludwig Koch
Carl Ludwig Koch (21 September 1778 – 23 August 1857) was a German entomologist and arachnologist. He was responsible for classifying a great number of spiders, including the Brazilian whiteknee tarantula and common house spider. He was born in Kusel, Germany, and died in Nuremberg, Germany. Carl Ludwig Koch was an inspector of water and forests. His principal work ''Die Arachniden'' (1831–1848) (16 volumes) was commenced by Carl Wilhelm Hahn (1786–1836). Koch was responsible for the last 12 volumes. He also finished the chapter on spiders in ''Faunae insectorum germanicae initia oder Deutschlands Insecten'' lements of the insect fauna of Germanya work by Georg Wolfgang Franz Panzer (1755–1829). He also co-authored, with Georg Karl Berendt, an important monograph ''Die im Bernstein befindlichen Myriapoden, Arachniden und Apteren der Vorwelt'' (1854) on arachnids, myriapods, and wingless insects in amber based on material in Berendt's collection, now held in the Muse ...

Hybrid (biology)
In biology, a hybrid is the offspring resulting from combining the qualities of two organisms of different breeds, varieties, species or genera through sexual reproduction. Hybrids are not always intermediates between their parents (such as in blending inheritance), but can show hybrid vigor, sometimes growing larger or taller than either parent. The concept of a hybrid is interpreted differently in animal and plant breeding, where there is interest in the individual parentage. In genetics, attention is focused on the numbers of chromosomes. In taxonomy, a key question is how closely related the parent species are. Species are reproductively isolated by strong barriers to hybridisation, which include genetic and morphological differences, differing times of fertility, mating behaviors and cues, and physiological rejection of sperm cells or the developing embryo. Some act before fertilization and others after it. Similar barriers exist in plants, with differences in flowering tim ...

Dendrocopos
''Dendrocopos'' is a widespread genus of woodpeckers from Asia, Europe and Northern Africa. The species range from the Philippines to the British Isles. Taxonomy The genus ''Dendrocopos'' was introduced in 1816 by the German naturalist Carl Ludwig Koch. The name combines the Ancient Greek ''dendron'' meaning "tree" with ''kopos'' meaning "striking". The type species was designated as the great spotted woodpecker (''Dendrocopos major'') by the Scottish ornithologist Edward Hargitt in 1890 in his catalogue of woodpeckers in the collection of the British Museum. The genus at one time contained around 25 species. A molecular phylogenetic analysis of the pied woodpeckers published in 2015 found that ''Dendrocopos'' was polyphyletic A polyphyletic group is an assemblage of organisms or other evolving elements that is of mixed evolutionary origin. The term is often applied to groups that share similar features known as homoplasies, which are explained as a result of conver .. ...
