Parrot Crossbill
The parrot crossbill (''Loxia pytyopsittacus'') is a small passerine bird in the finch family Fringillidae. It breeds in pine forests in northern and northeastern Europe. Taxonomy The parrot crossbill was formerly described in 1793 by the German naturalist Moritz Balthasar Borkhausen under the binomial name ''Loxia pytyopsittacus''. The type locality was designated as Sweden by Ernst Hartert. The species is monotypic: no subspecies are recognised. The genus name ''Loxia'' is from Ancient Greek ''loxos'' meaning "crosswise"; the specific epithet ''pytyopsittacus'' combines ''pitus, pituos'' meaning "pine" with ''psittakos'' meaning "parrot''.'' The crossbills are characterised by the mandibles crossing at their tips, which gives the group its English name. Some pine-feeding populations currently assigned to red crossbill in southern Europe may possibly be better referred to either this species or alternatively to new species in their own right, but as yet, research into the ...

Moritz Balthasar Borkhausen
Moritz Balthasar Borkhausen (3 December 1760, Giessen – 30 November 1806, Darmstadt) was a German naturalist and forester. He took part in the production of ' by Johann Conrad Susemihl. He received his education in Giessen, and in 1796 started work as an assessor at the forestry office in Darmstadt. In 1800, he attained the title of ''Kammerrat'', followed by a role as counselor at the Oberforsthaus Collegium in 1804.Borkhausen , eLexikon

Scottish Crossbill
The Scottish crossbill (''Loxia scotica'') is a small passerine bird in the finch family Fringillidae. It is endemic to the Caledonian Forests of Scotland, and is the only terrestrial vertebrate species endemic to the United Kingdom. The Scottish crossbill was confirmed as a unique species in August 2006, on the basis of having a distinctive bird song. The genus name ''Loxia'' is from Ancient Greek ''loxos'', 'crosswise', and ''scotica'' is Latin for 'Scottish'. The Scottish Gaelic name for a crossbill is ''Cam-ghob'', which means 'crooked beak'.' History and current status The British Ornithologists Union first classed the Scottish crossbill as a separate and distinct species in 1980, but some ornithologists believed there was insufficient scientific research for its status. It was considered to be possibly a race of either the red crossbill or the parrot crossbill, both of which also occur in the Caledonian Forest. RSPB research showed that Scottish crossbills have quite ...

Birds Of Europe
In this article, Europe refers to the geographical continent, not the somewhat larger Western Palearctic, which includes parts of the Middle East and north Africa. There are 930 species of bird in the area, and in general the avifauna is similar to Asia north of the Himalayas, which is also in the Palearctic realm. There are also many groups shared with North America. 65 species are globally threatened, 4 species are extinct, and 18 species are introduced by people. Conversely, many of the Southern Hemisphere groups, including the ancient flightless '' Struthioniformes'' (ostrich order), and their relatives the tinamous are not represented at all. The order follows th''IOC World Bird List''version 12.2. The following tags have been used to highlight several categories. The commonly occurring native species do not fall into any of these categories. * (A) Accidental - a species that rarely or accidentally occurs in Europe * (E) Endemic - a species endemic to Europe * (Ext) Ex ...

Loxia
The crossbill is a genus, ''Loxia'', of birds in the finch family (Fringillidae), with six species. These birds are characterised by the mandibles with crossed tips, which gives the group its English name. Adult males tend to be red or orange in colour, and females green or yellow, but there is much variation. Crossbills are specialist feeders on conifer cones, and the unusual bill shape is an adaptation which enables them to extract seeds from cones. These birds are typically found in higher northern hemisphere latitudes, where their food sources grow. They irrupt out of the breeding range when the cone crop fails. Crossbills breed very early in the year, often in winter months, to take advantage of maximum cone supplies. Systematics and evolution The genus ''Loxia'' was introduced by the Swedish naturalist Carl Linnaeus in 1758 in the 10th edition of his ''Systema Naturae''. The name is from the Ancient Greek , "crosswise". The Swiss naturalist Conrad Gessner had used the wor ...

Scots Pine
''Pinus sylvestris'', the Scots pine (UK), Scotch pine (US) or Baltic pine, is a species of tree in the pine family Pinaceae that is native to Eurasia. It can readily be identified by its combination of fairly short, blue-green leaves and orange-red bark. Description ''Pinus sylvestris'' is an evergreen coniferous tree growing up to in height and in trunk diameter when mature, exceptionally over tall and in trunk diameter on very productive sites. The tallest on record is a tree over 210 years old tree growing in Estonia which stands at . The lifespan is normally 150–300 years, with the oldest recorded specimens in Lapland, Northern Finland over 760 years. The bark is thick, flaky and orange-red when young to scaly and gray-brown in maturity, sometimes retaining the former on the upper portion.Trees for LifeSpecies profile: Scots pine/ref> The habit of the mature tree is distinctive due to its long, bare and straight trunk topped by a rounded or flat-topped mass of ...

Conifer
Conifers are a group of conifer cone, cone-bearing Spermatophyte, seed plants, a subset of gymnosperms. Scientifically, they make up the phylum, division Pinophyta (), also known as Coniferophyta () or Coniferae. The division contains a single extant class (biology), class, Pinopsida. All Neontology, extant conifers are perennial plant, perennial woody plants with secondary growth. The great majority are trees, though a few are shrubs. Examples include Cedrus, cedars, Pseudotsuga, Douglas-firs, Cupressaceae, cypresses, firs, junipers, Agathis, kauri, larches, pines, Tsuga, hemlocks, Sequoioideae, redwoods, spruces, and Taxaceae, yews.Campbell, Reece, "Phylum Coniferophyta". Biology. 7th. 2005. Print. P. 595 As of 1998, the division Pinophyta was estimated to contain eight families, 68 genera, and 629 living species. Although the total number of species is relatively small, conifers are ecology, ecologically important. They are the dominant plants over large areas of land, most ...

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 ...

Red Crossbill
The red crossbill or common crossbill (''Loxia curvirostra'') is a small passerine bird in the finch family Fringillidae. Crossbills have distinctive mandibles, crossed at the tips, which enable them to extract seeds from conifer cones and other fruits. Adults are often brightly coloured, with red or orange males and green or yellow females, but there is wide variation in beak size and shape, and call types, leading to different classifications of variants, some of which have been named as subspecies. The species is known as "red crossbill" in North America and "common crossbill" in Europe. Description Crossbills are characterized by the mandibles crossing at their tips, which gives the group its English name. Using their crossed mandibles for leverage, crossbills are able to efficiently separate the scales of conifer cones and extract the seeds on which they feed. Adult males tend to be red or orange in colour, and females green or yellow, but there is much variation. Identif ...

Scotland
Scotland (, ) is a country that is part of the United Kingdom. Covering the northern third of the island of Great Britain, mainland Scotland has a border with England to the southeast and is otherwise surrounded by the Atlantic Ocean to the north and west, the North Sea to the northeast and east, and the Irish Sea to the south. It also contains more than 790 islands, principally in the archipelagos of the Hebrides and the Northern Isles. Most of the population, including the capital Edinburgh, is concentrated in the Central Belt—the plain between the Scottish Highlands and the Southern Uplands—in the Scottish Lowlands. Scotland is divided into 32 administrative subdivisions or local authorities, known as council areas. Glasgow City is the largest council area in terms of population, with Highland being the largest in terms of area. Limited self-governing power, covering matters such as education, social services and roads and transportation, is devolved from the Scott ...
