Redpoll Way And Redstart Way In Abbeymead, Gloucester
The redpolls (genus ''Acanthis'') (in Great Britain also historically known as redpoles) are a group of small passerine birds in the finch family Fringillidae, which have characteristic red markings on their heads. They are placed in the genus ''Acanthis''. The genus name ''Acanthis'' is from the Ancient Greek ''akanthis'', a name for a small now-unidentifiable bird. All redpolls are northern breeding woodland species, associated with birch trees (although there are introduced populations in the southern hemisphere, in New Zealand and nearby subantarctic islands). They are small birds, brown or grey-brown above and with a red forehead patch. The adult male's breast is washed in red, but in females and young birds the buff breast and white belly are streaked with brown. The bill is small and yellow. Some birds, particularly young ones, are difficult to assign to species. They are primarily seed-eaters, and often feed acrobatically like a Titmouse, tit; their diet may include some ...

Common Redpoll
The common redpoll or mealy redpoll (''Acanthis flammea'') is a species of bird in the finch family. It breeds somewhat further south than the Arctic redpoll, also in habitats with thickets or shrubs. Taxonomy The common redpoll was listed in 1758 by Linnaeus in the 10th edition of his ''Systema Naturae'' under the binomial name ''Fringilla flammea''. The current genus name ''Acanthis'' is from the Ancient Greek ''akanthis'', a name for a small now-unidentifiable bird, and ''flammea'' is the Latin for "flame-coloured". The common redpoll was previously placed in the genus ''Carduelis''. Molecular phylogenetic studies showed that the Arctic redpoll, Arctic and common redpolls formed a distinct Lineage (evolution), lineage, so the two species were grouped together in the resurrected genus ''Redpoll, Acanthis''. Subspecies The Subspecies, nominate subspecies ''A. f. flammea'', the mealy redpoll, breeds across the northern parts of North America and the Palearctic. There is also a ...

Gene Expression
Gene expression is the process by which information from a gene is used in the synthesis of a functional gene product that enables it to produce end products, protein or non-coding RNA, and ultimately affect a phenotype, as the final effect. These products are often proteins, but in non-protein-coding genes such as transfer RNA (tRNA) and small nuclear RNA (snRNA), the product is a functional non-coding RNA. Gene expression is summarized in the central dogma of molecular biology first formulated by Francis Crick in 1958, further developed in his 1970 article, and expanded by the subsequent discoveries of reverse transcription and RNA replication. The process of gene expression is used by all known life—eukaryotes (including multicellular organisms), prokaryotes (bacteria and archaea), and utilized by viruses—to generate the macromolecular machinery for life. In genetics, gene expression is the most fundamental level at which the genotype gives rise to the phenotype, '' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Birds Of North America
The lists of birds in the light blue box below are divided by biological family. The lists are based on ''The AOS Check-list of North American Birds'' of the American Ornithological Society and ''The Clements Checklist of Birds of the World'' supplemented with checklists from Panama, Greenland, and Bermuda . It includes the birds of Greenland, Canada, the United States (excluding Hawaii), Mexico, Central America, Bermuda, and the West Indies. Taxonomy The taxonomic treatment (designation and sequence of orders, families and species) and nomenclature (common and scientific names) used in the accompanying bird lists adheres to the conventions of the AOS's (2019) ''Check-list of North American Birds'', the recognized scientific authority on the taxonomy and nomenclature of North America birds. The AOS's Committee on Classification and Nomenclature, the body responsible for maintaining and updating the ''Check-list'', "strongly and unanimously continues to endorse the biological sp ...

Birds Of Canada
This is a list of bird species confirmed in Canada. Unless otherwise noted, the list is that of ''Bird Checklists of the World'' as of July 2022. Of the 703 species listed here, 235 are accidental. Twelve species were introduced to North America or directly to Canada, three species are extinct, and three (possibly four) have been extirpated. One species of uncertain origin is also included. This list is presented in the taxonomic sequence of the ''Check-list of North and Middle American Birds'', 7th edition through the 63rd Supplement, published by the American Ornithological Society (AOS). Common and scientific names are also those of the ''Check-list'', except that the common names of families are from the Clements taxonomy because the AOS list does not include them. Canadian birds most closely resemble those of Eurasia, which was connected to the continent as part of the supercontinent Laurasia until around 60 million years ago. Many families which occur in Canada are a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lesser Redpoll
The lesser redpoll (''Acanthis cabaret'') is a small passerine bird in the finch family, Fringillidae. It is the smallest, brownest, and most streaked of the redpolls. It is sometimes classified as a subspecies of the common redpoll (''Acanthis flammea'') but has recently been split from that species by most taxonomies including Clements and the British Ornithologists' Union. It is native to Europe and has been introduced to New Zealand. Many birds migrate further south in winter, but the mild climate means that it can be found all year round in much of its range, and may be joined by the other two redpoll species in winter. Taxonomy The genus name ''Acanthis'' is from the Ancient Greek ''akanthis'', a name for a small now-unidentifiable bird, and ''cabaret'' is the French name for a type of finch. Redpolls were also previously placed in the genus Carduelis but were moved to their own genus along with a number of other changes in the genus. The relationships among the redpol ...

Carduelis Cabaret -Lochwinnoch, Renfrewshire, Scotland -female-8
The genus ''Carduelis'' is a group of birds in the finch family Fringillidae. The genus ''Carduelis'' was introduced by the French zoologist Mathurin Jacques Brisson in 1760 by tautonomy based on Carl Linnaeus's specific epithet for the European goldfinch ''Fringilla carduelis''. The name ''carduelis'' is the Latin word for the European goldfinch. Many bird species were at one time assigned to the genus, but it became clear from phylogenetic studies of mitochondrial and nuclear DNA sequences that the genus was polyphyletic. The polyphyletic nature of the genus was confirmed by Dario Zuccon and coworkers in a comprehensive study of the finch family published in 2012. The authors suggested splitting the genus into several monophyletic clades, a proposal that was accepted by the International Ornithologists' Union. The siskins and goldfinches from the Americas formed a distinct clade and were moved to the resurrected genus '' Spinus'', the greenfinches were moved to the genus ...

Arctic Redpoll
The Arctic redpoll or hoary redpoll (''Acanthis hornemanni'') is a bird species in the finch family Fringillidae. It breeds in tundra birch forest. It has two subspecies, ''A. h. hornemanni'' (Greenland or Hornemann's Arctic redpoll) of Greenland and neighbouring parts of Canada, and ''A. h. exilipes'' (Coues' Arctic redpoll), which breeds in the tundra of northern North America and the Palearctic. Many birds remain in the far north; some birds migrate short distances south in winter, sometimes travelling with common redpolls. The genus name ''Acanthis'' is from the Ancient Greek ''akanthis'', a name for a small now-unidentifiable bird, and ''hornemanni'' commemorates the Danish botanist Jens Wilken Hornemann. The name "arctic redpoll" is used in Europe and "hoary redpoll" in North America. Description The Arctic redpoll is similar in appearance to the common redpoll but generally paler. It may be distinguished from that species by the unstreaked pale rump patch and the unifor ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
