Golden-crowned Kinglet
The golden-crowned kinglet (''Regulus satrapa'') is a very small songbird in the family Regulidae that lives throughout much of North America. Description Adults are olive-gray on the upperparts with white underparts, with thin bills and short tails. They have white wing bars, a black stripe through the eyes and a yellow crown surrounded by black. The adult male has an orange patch in the middle of the yellow crown. The juvenile is similar to the adult, but with a browner back and without the yellow crown. This is one of the smallest passerines in North America. Its length, at , is probably the shortest of any American passerine. Its weight, averaging for females and 6.3 g (0.22 oz) for males and ranging from , is similar to the American bushtit and black-tailed gnatcatcher. The golden-crowned kinglet has a wingspan of 5.5–7.1 in (14–18 cm). Ecology The golden-crowned kinglet is insectivorous, foraging in trees or shrubs, where it eats insects (especially caterp ...

Goldcrest
The goldcrest (''Regulus regulus'') is a very small passerine bird in the kinglet family. Its colourful golden Crest (feathers), crest feathers, as well as being called the "king of the birds" in European folklore, gives rise to its English and scientific names. The scientific name, ''R. regulus'', means 'petty king' or prince. Several subspecies are recognised across the very large distribution range that includes much of the Palearctic and the islands of Macaronesia and Iceland. Birds from the north and east of its breeding range bird migration, migrate to winter further south. This kinglet has greenish upper-parts, whitish under-parts, and has two white wingbars. It has a plain face contrasting black irises and a bright head crest, orange and yellow in the male and yellow in the female, which is display (zoology), displayed during breeding. It superficially resembles the common firecrest (''Regulus ignicapilla''), which largely shares its European range, but the latter's ...

Birds Of Central America
Birds are a group of warm-blooded vertebrates constituting the class (biology), class Aves (), characterised by feathers, toothless beaked jaws, the Oviparity, laying of Eggshell, hard-shelled eggs, a high Metabolism, metabolic rate, a four-chambered heart, and a strong yet lightweight Bird skeleton, skeleton. Birds live worldwide and range in size from the bee hummingbird to the common ostrich. There are over 11,000 living species and they are split into 44 Order (biology), orders. More than half are passerine or "perching" birds. Birds have Bird wing, wings whose development varies according to species; the only known groups without wings are the extinct moa and elephant birds. Wings, which are modified forelimbs, gave birds the ability to fly, although further evolution has led to the Flightless bird, loss of flight in some birds, including ratites, penguins, and diverse endemism, endemic island species. The digestive and respiratory systems of birds are also uniquely a ... [...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 spe ...

Regulus (bird)
''Regulus'' is a genus of bird in the family Kinglet, Regulidae. It contains most kinglet species aside from the ruby-crowned kinglet (''Corthylio calendula''), which was formerly classified in ''Regulus'' but is now known to belong to its own genus. Taxonomy The name of the genus is derived from the Latin ''regulus'', a diminutive of ''rex'', "a king", and refers to the characteristic orange or yellow crests of adult kinglets. Several forms have only recently had their status clarified. The Madeira firecrest was formerly considered to be a subspecies, ''R. i. madeirensis'', of the common firecrest ''R. ignicapillus''. A Phylogenetics, phylogenetic analysis based on the cytochrome b gene showed that the Madeiran form is distinct at the species level from the firecrest Subspecies#Nomenclature, nominate subspecies ''R. i. ignicapillus''. Cytochrome ''b'' gene divergence between the Madeira firecrest and the European bird is 8.5%, comparable with the divergence level between othe ...

Subspecies
In Taxonomy (biology), biological classification, subspecies (: subspecies) is a rank below species, used for populations that live in different areas and vary in size, shape, or other physical characteristics (Morphology (biology), morphology), but that can successfully interbreed. Not all species have subspecies, but for those that do there must be at least two. Subspecies is abbreviated as subsp. or ssp. and the singular and plural forms are the same ("the subspecies is" or "the subspecies are"). In zoology, under the International Code of Zoological Nomenclature, the subspecies is the only taxonomic rank below that of species that can receive a name. In botany and mycology, under the International Code of Nomenclature for algae, fungi, and plants, other infraspecific name, infraspecific ranks, such as variety (botany), variety, may be named. In bacteriology and virology, under standard International Code of Nomenclature of Prokaryotes, bacterial nomenclature and virus clas ...

Old World Warbler
The Old World warblers are a large group of birds formerly grouped together in the bird family Sylviidae. They are not closely related to the New World warblers. The family held over 400 species in over 70 genera, and were the source of much taxonomic confusion. Two families were split out initially, the cisticolas into Cisticolidae and the kinglets into Regulidae. In the past 20–30 years they have been the subject of much research and many species are now placed into other families, including the Acrocephalidae, Cettiidae, Phylloscopidae, and Megaluridae. In addition some species have been moved into existing families or have not yet had their placement fully resolved. Only a small number of warblers, in just two genera, are now retained in the family Sylviidae. Characteristics Most Old World warblers are of generally undistinguished appearance, though some species are boldly marked. The sexes are often identical, but may be clearly distinct, notably in the genera '' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ruby-crowned Kinglet
The ruby-crowned kinglet (''Corthylio calendula'') is a very small passerine bird found throughout North America. It is a member of the kinglet family. The bird has olive-green plumage with two white wing bars and a white eye-ring. Males have a red crown patch, which is often concealed. The sexes are identical apart from the crown, and juveniles are similar in plumage to adult females. It is one of the smallest songbirds in North America. The ruby-crowned kinglet is not closely related to other kinglets and was moved from ''Regulus (bird), Regulus'' to its own genus, ''Corthylio'' in 2021. Three subspecies are currently recognized. The kinglet is mostly migratory, and its range extends from northwest Canada and Alaska south to Mexico. Its breeding habitat is spruce-fir forests in the northern and mountainous regions of the United States and Canada. The ruby-crowned kinglet builds a cup-shaped bird nest, nest, which may be pensile or placed on a tree branch and is often hidden. It ...

Central America
Central America is a subregion of North America. Its political boundaries are defined as bordering Mexico to the north, Colombia to the southeast, the Caribbean to the east, and the Pacific Ocean to the southwest. Central America is usually defined as consisting of seven countries: Belize, Costa Rica, El Salvador, Guatemala, Honduras, Nicaragua, and Panama. Within Central America is the Mesoamerican biodiversity hotspot, which extends from southern Mexico to southeastern Panama. Due to the presence of several active geologic faults and the Central America Volcanic Arc, there is a high amount of seismic activity in the region, such as volcanic eruptions and earthquakes, which has resulted in death, injury, and property damage. Most of Central America falls under the Isthmo-Colombian cultural area. Before the Spanish expedition of Christopher Columbus' voyages to the Americas, hundreds of indigenous peoples made their homes in the area. From the year 1502 onwards, Spain ...
