Selasphorus Rufus1
''Selasphorus'' is a genus of hummingbirds from Middle and North America. Taxonomy The genus ''Selasphorus'' was introduced in 1832 by the English naturalist William John Swainson to accommodate the rufous hummingbird which is now the type species. The name combines the Ancient Greek ''selas'' meaning "light" or "flame" with ''-phoros'' meaning "-carrying". The genus contains the following nine species: The wine-throated hummingbird and the bumblebee hummingbird were formerly placed in the genus ''Atthis''. Molecular phylogenetic Molecular phylogenetics () is the branch of phylogeny that analyzes genetic, hereditary molecular differences, predominantly in DNA sequences, to gain information on an organism's evolutionary relationships. From these analyses, it is possible to ... studies published in 2014 and 2017 found that ''Atthis'' was embedded within ''Selasphorus''. The genera were therefore merged and these hummingbirds were moved to ''Selasphorus''. References Ex ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Broad-tailed Hummingbird
The broad-tailed hummingbird (''Selasphorus platycercus'') is a medium-sized hummingbird species found in highland regions from western United States and Western Canada to Mexico and Guatemala. Description Medium in size, the broad-tailed hummingbird is in length and possesses an overall wingspan of . Weighing around , the female tends to be slightly larger than the male. Adults of both sexes show an iridescent green back, white eye ring and a rounded black tail projecting beyond their wing tips, from which their name was inspired. This species shows sexual dimorphism, which means that male and female have different characteristics. The male possesses a characteristic bright rose-red gorget. An identification characteristic is the white eye ring. The female can be distinguished from the male by her paler coloration, cinnamon flanks, and spotted cheeks absent in the male.

Wine-throated Hummingbird
The wine-throated hummingbird (''Selasphorus ellioti'') is a species of hummingbird in tribe Mellisugini of subfamily Trochilinae, the "bee hummingbirds". It is found in El Salvador, Guatemala, Honduras, and Mexico. Taxonomy and systematics The International Ornithological Committee (IOC), the North American Classification Committee of the American Ornithological Society, and the Clements taxonomy place the wine-throated hummingbird in genus ''Selasphorus''. BirdLife International's Handbook of the Birds of the World (HBW) places it in genus ''Atthis''. The three worldwide taxonomic systems assign two subspecies, the nominate ''S. e. ellioti''/''A. e. ellioti'' and ''S. e. selasphoroides''/''A. e. selasphoroides''.Clements, J. F., T. S.

Molecular Phylogenetic
Molecular phylogenetics () is the branch of phylogeny that analyzes genetic, hereditary molecular differences, predominantly in DNA sequences, to gain information on an organism's evolutionary relationships. From these analyses, it is possible to determine the processes by which diversity among species has been achieved. The result of a molecular phylogenetic analysis is expressed in a phylogenetic tree. Molecular phylogenetics is one aspect of molecular systematics, a broader term that also includes the use of molecular data in taxonomy and biogeography. Molecular phylogenetics and molecular evolution correlate. Molecular evolution is the process of selective changes (mutations) at a molecular level (genes, proteins, etc.) throughout various branches in the tree of life (evolution). Molecular phylogenetics makes inferences of the evolutionary relationships that arise due to molecular evolution and results in the construction of a phylogenetic tree.

Scintillant Hummingbird
The scintillant hummingbird (''Selasphorus scintilla'') is a hummingbird endemic to Costa Rica and Panama. This species is replaced at higher elevations by its relative, the volcano hummingbird, ''S. flammula''. Habitat It inhabits brushy forest edges, coffee plantations and sometimes gardens at altitudes from , and up to when not breeding. Description It is only long, including the bill. The male weighs and the female . This is one of the smallest birds in existence, marginally larger than the bee hummingbird. The black bill is short and straight. The adult male scintillant hummingbird has bronze-green upperparts and a rufous and black-striped tail. The throat is brilliant red, separated from the cinnamon underparts by a white neck band. The female is similar, but her throat is buff with small green spots and the flanks are richer rufous. Young birds resemble the female but have rufous fringes to the upperpart plumage. Breeding The female scintillant hummingbird is e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Allen's Hummingbird
Allen's hummingbird (''Selasphorus sasin'') is a species of hummingbird that breeds in the western United States. It is one of seven species in the genus ''Selasphorus''. Description Allen's hummingbird is a small bird, with mature adults reaching only in length. The male has a green back and forehead, with rust-colored (rufous) flanks, rump, and tail. The male's throat is an iridescent orange-red. The female and immature Allen's hummingbirds are similarly colored, but lack the iridescent throat patch, instead having a series of speckles on their throats. Females are mostly green, featuring rufous color only on the tail, which also has white tips. Immature Allen's hummingbirds are so similar to the female rufous hummingbird, the two are almost indistinguishable in the field. The lack of a notch in the second rectrix (R2) is considered an important field mark to distinguish the adult male Allen's hummingbird from rufous hummingbird, particularly the hard to distinguish green-b ...

Rufous Hummingbird (29586787801)
The rufous hummingbird (''Selasphorus rufus'') is a small hummingbird, about long with a long, straight and slender bill. These birds are known for their extraordinary flight skills, flying during their migratory transits. It is one of nine species in the genus ''Selasphorus''. Taxonomy The rufous hummingbird was formally described in 1788 by the German naturalist Johann Friedrich Gmelin in his revised and expanded edition of Carl Linnaeus's ''Systema Naturae''. He placed it with all the other hummingbirds in the genus ''Trochilus'' and coined the binomial name ''Trochilus rufus''. Gmelin based his description on the ''Ruff-necked humming-bird'' that had been described by John Latham in 1782 and the ''Ruffed honeysucker'' that had been described by Thomas Pennant in 1785. The type locality is Nootka Sound on the west coast of Vancouver Island in western Canada. The rufous hummingbird is now placed with eight other species in the genus ''Selasphorus'' that was introduced in 1 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
