Chaffinch
The common chaffinch or simply the chaffinch (''Fringilla coelebs'') is a common and widespread small passerine bird in the finch family. The male is brightly coloured with a blue-grey cap and rust-red underparts. The female is more subdued in colouring, but both sexes have two contrasting white wing bars and white sides to the tail. The male bird has a strong voice and sings from exposed perches to attract a mate. The chaffinch breeds in much of Europe, across the Palearctic to Siberia and in northwestern Africa. The female builds a nest with a deep cup in the fork of a tree. The clutch is typically four or five eggs, which hatch in about 13 days. The chicks fledge in around 14 days, but are fed by both adults for several weeks after leaving the nest. Outside the breeding season, chaffinches form flocks in open countryside and forage for seeds on the ground. During the breeding season, they forage on trees for invertebrates, especially caterpillars, and feed these to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Gran Canaria Blue Chaffinch
The Gran Canaria blue chaffinch (''Fringilla polatzeki'') is a species of passerine bird in the finch family Fringillidae. It is endemic to Gran Canaria in Spain's Canary Islands. Taxonomy Until 2015, the species ''Fringilla teydea'' was classified with two subspecies: ''Fringilla teydea polatzeki'' from Gran Canaria and ''Fringilla teydea teydea'' from Tenerife. However, a study published in March 2016 showed that a classification as different species, ''Frigilla polatzeki'' and ''Fringilla teydea'', is justified.George Sangster, Felipe Rodríguez Godoy, C.

Luksenbur«Integrative taxonomy reveals Europe’s rarest songbird species, the Gran Canaria Blue Chaffinch ''Fringilla polatzeki''.»/ref> Description Gran Canaria blue chaffinches resemble common chaffinches, and are smaller in size than Tenerife blue chaffinches.

Fringilla
The genus ''Fringilla'' is a small group of finches from the Old World, which are the only species in the subfamily Fringillinae. The genus name ''Fringilla'' is Latin for "finch". Taxonomy The genus ''Fringilla'' was introduced in 1758 by the Swedish naturalist Carl Linnaeus in the tenth edition of his ''Systema Naturae''. The genus name ''Fringilla'' is Latin for "finch". Linnaeus included 30 species in the genus (''Fringilla zena'' was listed twice) and of these the common chaffinch (''Fringilla coelebs'') is considered as the type species. Species The genus now contains four species: The common chaffinch is found primarily in forest habitats, in Europe, North Africa, and western Asia; the blue chaffinches are island endemics; and the brambling breeds in the northern taiga and southern tundra of Eurasia Eurasia (, ) is the largest continental area on Earth, comprising all of Europe and Asia.

Fringillidae
The true finches are small to medium-sized passerine birds in the family Fringillidae. Finches have stout conical bills adapted for eating seeds and nuts and often have colourful plumage. They occupy a great range of habitats where they are usually resident and do not migrate. They have a worldwide distribution except for Australia and the polar regions. The family Fringillidae contains more than two hundred species divided into fifty genera. It includes species known as siskins, canaries, redpolls, serins, grosbeaks and euphonias. Many birds in other families are also commonly called "finches". These groups include the estrildid finches (Estrildidae) of the Old World tropics and Australia; some members of the Old World bunting family (Emberizidae) and the New World sparrow family (Passerellidae); and the Darwin's finches of the Galapagos islands, now considered members of the tanager family (Thraupidae).Newton (1973), Clement ''et al.''

Bird Migration
Bird migration is the regular seasonal movement, often north and south along a flyway, between breeding and wintering grounds. Many species of bird migrate. Migration carries high costs in predation and mortality, including from hunting by humans, and is driven primarily by the availability of food. It occurs mainly in the northern hemisphere, where birds are funneled onto specific routes by natural barriers such as the Mediterranean Sea or the Caribbean Sea. Migration of species such as storks, turtle doves, and swallows was recorded as many as 3,000 years ago by Ancient Greek authors, including Homer and Aristotle, and in the Book of Job. More recently, Johannes Leche began recording dates of arrivals of spring migrants in Finland in 1749, and modern scientific studies have used techniques including bird ringing and satellite tracking to trace migrants. Threats to migratory birds have grown with habitat destruction, especially of stopover and wintering sites, as wel ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sherborne Missal
The Sherborne Missal (London, British Library, Add MS 74236) is an early 15th-century English illuminated manuscript missal, one of the finest English examples of International Gothic painting. With 347 vellum leaves measuring , it weighs 20 kg. It has survived in excellent condition, and is usually on display at the Ritblat Gallery in the British Library. It has been described as "beyond question the most spectacular service book of English execution to have come down to us from the later Middle Ages."Monckton (2000), 108 The Sherborne Missal was commissioned by Robert Bruyning, who served as abbot at the Sherborne Abbey, Abbey of St Mary in Sherborne in Dorset from 1385 to 1415. It was made for use at the abbey sometime between 1399 and 1407. The main scribe was a Benedictine monk of Sherborne Abbey, John Whas. Several hands worked on the illumination but the main artist was John Siferwas, a Dominican Order, Dominican friar. Both of them, alongside Bruyning and his superio ...

Passerine
A passerine () is any bird of the order Passeriformes (; from Latin 'sparrow' and '-shaped'), which includes more than half of all bird species. Sometimes known as perching birds, passerines are distinguished from other orders of birds by the arrangement of their toes (three pointing forward and one back), which facilitates perching. With more than 140 families and some 6,500 identified species, Passeriformes is the largest clade of birds and among the most diverse clades of terrestrial vertebrates, representing 60% of birds.Ericson, P.G.P. et al. (2003Evolution, biogeography, and patterns of diversification in passerine birds ''J. Avian Biol'', 34:3–15.Selvatti, A.P. et al. (2015"A Paleogene origin for crown passerines and the diversification of the Oscines in the New World" ''Molecular Phylogenetics and Evolution'', 88:1–15.

Chaff
Chaff (; ) is the dry, scaly protective casing of the seeds of cereal grains or similar fine, dry, scaly plant material (such as scaly parts of flowers or finely chopped straw). Chaff is indigestible by humans, but livestock can eat it. In agriculture it is used as livestock fodder, or is a waste material ploughed into the soil or burned. Etymology "Chaff" comes from Middle English ''chaf'', from Old English , related to Old High German ''cheva'', "husk". Grain chaff In grasses (including cereals such as rice, barley, oats, and wheat), the ripe seed is surrounded by thin, dry, scaly bracts (called glumes, lemmas and paleas), forming a dry husk (or hull) around the grain. Once it is removed it is often referred to as chaff. In wild cereals and in the primitive domesticated einkorn,Potts, D. T. (1996) ''Mesopotamia Civilization: The Material Foundations'' Cornell University Press. p. 62. . emmer and spelt wheats, the husks enclose each seed tightly. Before the grain can ...

Crop (anatomy)
A crop (sometimes also called a croup or a craw, ingluvies, or sublingual pouch) is a thin-walled expanded portion of the alimentary tract used for the storage of food prior to digestion. This anatomical structure is found in a wide variety of animals. It has been found in birds, and in invertebrate animals including gastropods (snails and slugs), earthworms, leeches, and insects. Insects Cropping is used by bees to temporarily store nectar of flowers. When bees "suck" nectar, it is stored in their crops. Other Hymenoptera also use crops to store liquid food. The crop in eusocial insects, such as ants, has specialized to be distensible, and this specialization enables important communication between colonial insects through trophallaxis. The crop can be found in the foregut of insects. Birds In a bird's digestive system, the crop is an expanded, muscular pouch near the gullet or throat. It is a part of the digestive tract, essentially an enlarged part of the esophagus ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
