Parrotbills
The parrotbills are a family, Paradoxornithidae, of passerine birds that are primarily native to Eastern Asia, East, Southeast Asia, Southeast and South Asia, with a single species in western North America, though feral populations exist elsewhere. They are generally small birds that inhabit reedbeds, forests and similar habitats. The traditional parrotbills feed mainly on seeds, e.g. of grasses, to which their robust bill, as the name implies, is well-adaptation (biology), adapted. Members of the family are usually non-bird migration, migratory. The bearded reedling or "bearded tit", a Eurasian species formerly placed here, is more insectivorous by comparison, especially in summer. It also strikingly differs in morphology (biology), morphology, such as its finer bill, and has again been moved to the monotypic family Panuridae. Conversely, a number of other mostly insectivorous species that traditionally were placed in Timaliidae (Old World babblers), for example the fulvettas a ...

Suthora
''Suthora'' is a genus of parrotbills in the family Paradoxornithidae. Taxonomy The genus ''Suthora'' was introduced in 1837 by the English naturalist Brian Houghton Hodgson with the type species In International_Code_of_Zoological_Nomenclature, zoological nomenclature, a type species (''species typica'') is the species name with which the name of a genus or subgenus is considered to be permanently taxonomically associated, i.e., the spe ... as ''Suthora nipalensis'', the black-throated parrotbill. The genus name is the Nepalese word for the black-throated parrotbill (''Suthora nipalensis''). The genus now includes species formerly placed in the genera ''Neosuthora'', ''Chleuasicus'', and ''Sinosuthora''. These genera are now considered as junior synonyms of ''Suthora'' based on the results of a molecular phylogenetic study by Tianlong Cai and collaborators published in 2019.

Bird Migration
Bird migration is a seasonal movement of birds between breeding and wintering grounds that occurs twice a year. It is typically from north to south or from south to north. Animal migration, Migration is inherently risky, due to predation and mortality. The Arctic tern holds the long-distance migration record for birds, travelling between Arctic breeding grounds and the Antarctic each year. Some species of Procellariiformes, tubenoses, such as albatrosses, circle the Earth, flying over the southern oceans, while others such as Manx shearwaters migrate between their northern breeding grounds and the southern ocean. Shorter migrations are common, while longer ones are not. The shorter migrations include altitudinal migrations on mountains, including the Andes and Himalayas. The timing of migration seems to be controlled primarily by changes in day length. Migrating birds navigate using celestial cues from the Sun and stars, the Earth's magnetic field, and mental maps.

Family (biology)
Family (, : ) is one of the eight major hierarchical taxonomic ranks in Linnaean taxonomy. It is classified between order and genus. A family may be divided into subfamilies, which are intermediate ranks between the ranks of family and genus. The official family names are Latin in origin; however, popular names are often used: for example, walnut trees and hickory trees belong to the family Juglandaceae, but that family is commonly referred to as the "walnut family". The delineation of what constitutes a family—or whether a described family should be acknowledged—is established and decided upon by active taxonomists. There are not strict regulations for outlining or acknowledging a family, yet in the realm of plants, these classifications often rely on both the vegetative and reproductive characteristics of plant species. Taxonomists frequently hold varying perspectives on these descriptions, leading to a lack of widespread consensus within the scientific community ...

Long-tailed Tit
The long-tailed tit (''Aegithalos caudatus''), also named long-tailed bushtit, is a common bird found throughout Europe and the Palearctic. The genus name ''Aegithalos'' was a term used by Aristotle for some European tits, including the long-tailed tit. Taxonomy and systematics The long-tailed tit was formally described by the Swedish naturalist Carl Linnaeus in 1758 in the tenth edition of his ''Systema Naturae'' under the binomial name ''Parus caudatus''. The specific epithet ''caudatus'' is the Latin word for "tailed". Linnaeus did not invent this Latin name. "''Parus caudatus''" had been used by earlier authors such as the Swiss naturalist Conrad Gessner in 1555, the Italian naturalist Ulisse Aldrovandi in 1599, and the English ornithologist Francis Willughby in 1676. Willughby listed the English name as the "long tail'd titmouse". Its previous common nickname in everyday English was the bum-towel, from the shape of its tail. The long-tailed tit was first classified as a t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
DNA Sequence
A nucleic acid sequence is a succession of bases within the nucleotides forming alleles within a DNA (using GACT) or RNA (GACU) molecule. This succession is denoted by a series of a set of five different letters that indicate the order of the nucleotides. By convention, sequences are usually presented from the 5' end to the 3' end. For DNA, with its double helix, there are two possible directions for the notated sequence; of these two, the sense strand is used. Because nucleic acids are normally linear (unbranched) polymers, specifying the sequence is equivalent to defining the covalent structure of the entire molecule. For this reason, the nucleic acid sequence is also termed the primary structure. The sequence represents genetic information. Biological deoxyribonucleic acid represents the information which directs the functions of an organism. Nucleic acids also have a secondary structure and tertiary structure. Primary structure is sometimes mistakenly referred to as "prim ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wrentit
The wrentit (''Chamaea fasciata'') is a small bird that lives in chaparral, California oak woodland, oak woodlands, and bushland on the western coast of North America. It is the Monotypic taxon, only species in the genus ''Chamaea''. Its systematics have been the subject of much debate, the wrentit having been placed in many different family (biology), families by different authors for as long as it has been known to science. Its common name reflects the uncertainty, and its external resemblance to both Paridae, tits and wrens. It is not related to either, however. More recent and comprehensive phylogenetic studies support it belonging to the parrotbills. Description The wrentit is a small, bird with uniform dull olive, brown, or grayish plumage. It has short wings and a long tail often held high (hence the comparison to wrens). It has a short beak, bill and a pale iris. Given its retiring nature and loud voice, the wrentit is more likely to be detected by its call than by sigh ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fire-tailed Myzornis
The fire-tailed myzornis (''Myzornis pyrrhoura'') is a species of bird. Its genus ''Myzornis'' is monotypic, and has recently been placed in the family Paradoxornithidae. Description The fire-tailed myzornis is a small species of warbler, long and weighing . It has bright green plumage with a black mask around the eyes and black scalloping on the .

Fulvetta
''Fulvetta'' is a genus of passerine birds. Originally proposed in 1877, it was recently reestablished for the typical fulvettas, which were long included with their presumed relatives in the Timaliidae (Old World babbler) genus ''Alcippe (bird), Alcippe''.Collar & Robson (2007) But they are actually quite closely related to the Parrotbill, parrotbills, and are thus now placed in the family (biology), family Paradoxornithidae. The genus contains the following eight species: * Spectacled fulvetta, ''Fulvetta ruficapilla'' * Indochinese fulvetta, ''Fulvetta danisi'' * Chinese fulvetta, ''Fulvetta striaticollis'' * White-browed fulvetta, ''Fulvetta vinipectus'' * Grey-hooded fulvetta, ''Fulvetta cinereiceps'' * Taiwan fulvetta, ''Fulvetta formosana'' * Manipur fulvetta, ''Fulvetta manipurensis'' * Brown-throated fulvetta, ''Fulvetta ludlowi'' References * Collar, N.J. & Robson, Craig (2007): Family Timaliidae (Babblers).

Monotypic
In biology, a monotypic taxon is a taxonomic group (taxon) that contains only one immediately subordinate taxon. A monotypic species is one that does not include subspecies or smaller, infraspecific taxa. In the case of genera, the term "unispecific" or "monospecific" is sometimes preferred. In botanical nomenclature, a monotypic genus is a genus in the special case where a genus and a single species are simultaneously described. Theoretical implications Monotypic taxa present several important theoretical challenges in biological classification. One key issue is known as "Gregg's Paradox": if a single species is the only member of multiple hierarchical levels (for example, being the only species in its genus, which is the only genus in its family), then each level needs a distinct definition to maintain logical structure. Otherwise, the different taxonomic ranks become effectively identical, which creates problems for organizing biological diversity in a hierarchical syste ...
