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. Vocalizations The broad-tailed hummingbird produces several different sound patterns. This bird's call ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Hummingbird
Hummingbirds are birds native to the Americas and comprise the Family (biology), biological family Trochilidae. With approximately 366 species and 113 genus, genera, they occur from Alaska to Tierra del Fuego, but most species are found in Central America, Central and South America. As of 2024, 21 hummingbird species are listed as Endangered species, endangered or critically endangered, with numerous species declining in population. Hummingbirds have varied specialized characteristics to enable rapid, maneuverable flight: exceptional metabolism, metabolic capacity, adaptations to high altitude, sensitive visual and communication abilities, and long-distance migration in some species. Among all birds, male hummingbirds have the widest diversity of plumage color, particularly in blues, greens, and purples. Hummingbirds are the smallest mature birds, measuring in length. The smallest is the bee hummingbird, which weighs less than , and the largest is the giant hummingbird, weig ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Species
A species () is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can produce fertile offspring, typically by sexual reproduction. It is the basic unit of Taxonomy (biology), classification and a taxonomic rank of an organism, as well as a unit of biodiversity. Other ways of defining species include their karyotype, DNA sequence, morphology (biology), morphology, behaviour, or ecological niche. In addition, palaeontologists use the concept of the chronospecies since fossil reproduction cannot be examined. The most recent rigorous estimate for the total number of species of eukaryotes is between 8 and 8.7 million. About 14% of these had been described by 2011. All species (except viruses) are given a binomial nomenclature, two-part name, a "binomen". The first part of a binomen is the name of a genus to which the species belongs. The second part is called the specific name (zoology), specific name or the specific ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Rufous Hummingbird
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 hummingbird described by John Latham in 1782 and the ruffed honeysucker described by Thomas Pennant in 1785. The type locality given by Gmelin was Nootka Sound on the west coast of Vancouver Island in western Canada, although breeding was estimated to occur in northwestern North America and wintering in westcentral Mexico.

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 and weighing approximately 2 to 4 grams in weight. They are known for their vibrant colors and energetic behaviors, making them a popular subject for birdwatchers and nature enthusiasts. 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 male hummingbirds make use of their elaborate colors to impress the females, which is crucial for mating season. 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 ...

Gorget
A gorget ( ; ) was a band of linen wrapped around a woman's neck and head in the English medieval clothing, medieval period or the lower part of a simple chaperon (headgear), chaperon hood. The term later described a steel or leather Collar (clothing), collar to protect the throat, a set of pieces of plate armour, or a single piece of plate armour hanging from the neck and covering the throat and chest. Later, particularly from the 18th century, the gorget became primarily ornamental, serving as a symbolic accessory on military uniforms, a use which has survived in some armies (see below). The term may also be used for other things such as items of jewellery worn around the throat region in several societies, for example wide thin gold collars found in prehistoric Ireland dating to the Bronze Age. As part of armour In the High Middle Ages, when Mail (armour), mail was the primary form of metal body armour used in Western Europe, the mail coif protected the neck and lower fa ...

Genus
Genus (; : genera ) is a taxonomic rank above species and below family (taxonomy), family as used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. ''Panthera leo'' (lion) and ''Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomy (biology), taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants of an ancestral taxon are grouped together (i.e. Phylogeneti ...

Selasphorus
''Selasphorus'' is a genus of hummingbirds from Middle and North America. Taxonomy The genus ''Selasphorus'' was introduced in 1832 by the English naturalist William 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''. Re ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
