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] |
Perisoreus Canadensis Mercier2
The genus ''Perisoreus'' is a very small genus of jays from the Boreal ecosystem, Boreal regions of North America and Eurasia from Scandinavia to the Asian seaboard. An isolated species also occurs in north-western Szechuan province of China. They belong to the Passerine order of birds in the family Corvidae. Not closely related to other birds known as jays, they are instead related to the genus ''Cyanopica''. The genus was introduced by the French zoologist Charles Lucien Bonaparte in 1831. The type species was subsequently designated as the Canada jay. The name of the genus may come from the Ancient Greek ''perisōreuō'' "to heap up" or "bury beneath". Alternatively it may be from the Latin ''peri-'' "very" or "exceedingly" and ''sorix'', a bird of augury dedicated to Saturn. Species The genus contains three species.

New World Quail
The New World quail are small birds only distantly related to the Old World quail, but named for their similar appearance and habits. The American species are in their own family, the Odontophoridae, whereas Old World quail are in the pheasant family Phasianidae. The family ranges from Canada through to southern Brazil, and two species, the California quail and the bobwhite quail, have been successfully introduced to New Zealand. The stone partridge and Nahan's partridge, both found in Africa, seem to belong to the family. Species are found across a variety of habitats from tropical rainforest to deserts, although few species are capable of surviving at very low temperatures. The 34 species are placed in 10 genera. The legs of most New World quails are short but powerful, with some species having very thick legs for digging. They lack the spurs of many Old World galliformes. Although they are capable of short bursts of strong flight, New World quails prefer to walk, and run fr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Black-bellied Whistling-duck
The black-bellied whistling duck (''Dendrocygna autumnalis''), formerly called the black-bellied tree duck, is a whistling duck that breeds from the southernmost United States, Mexico, and tropical Central to south-central South America. In the US, it can be found year-round in peninsular Florida, parts of southeast Texas, coastal Alabama and Mississippi and seasonally in southeast Arizona, and Louisiana's Gulf Coast. It is a rare breeder in such disparate locations as Arkansas, Georgia, Tennessee, and South Carolina, though it is now a common breeder in parts of central Florida. There is a large population of several hundred that winter each year in Audubon Park in uptown New Orleans, Louisiana. Since it is one of only two whistling duck species native to North America, it is occasionally just known as the "whistling duck" or "Mexican squealer" in the southern USA. Taxonomy In 1751 the English naturalist George Edwards included an illustration and a description of the black-bel ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Anatidae
The Anatidae are the biological family of water birds that includes ducks, geese, and swans. The family has a cosmopolitan distribution, occurring on all the world's continents except Antarctica. These birds are adapted for swimming, floating on the water surface, and in some cases diving in at least shallow water. The family contains around 174 species in 43 genera. (The magpie goose is no longer considered to be part of the Anatidae and is now placed in its own family, Anseranatidae.) They are generally herbivorous, and are monogamous breeders. A number of species undertake annual migrations. A few species have been domesticated for agriculture, and many others are hunted for food and recreation. Five species have become extinct since 1600, and many more are threatened with extinction. Description and ecology The ducks, geese, and swans are small- to large-sized birds with a broad and elongated general body plan. Diving species vary from this in being rounder. Extant s ...

Anseriformes
Anseriformes is an order of birds also known as waterfowl that comprises about 180 living species of birds in three families: Anhimidae (three species of screamers), Anseranatidae (the magpie goose), and Anatidae, the largest family, which includes over 170 species of waterfowl, among them the ducks, geese, and swans. Most modern species in the order are highly adapted for an aquatic existence at the water surface. With the exception of screamers, males have penises, a trait that has been lost in the Neoaves. Due to their aquatic nature, most species are web-footed. Evolution Anseriformes are one of only two types of modern bird to be confirmed present during the Mesozoic alongside the other dinosaurs, and in fact were among the very few birds to survive their extinction, along with their cousins the galliformes. These two groups only occupied two ecological niches during the Mesozoic, living in water and on the ground, while the toothed enantiornithes were the dominant bird ...

Bristol
Bristol () is a city, ceremonial county and unitary authority in England. Situated on the River Avon, it is bordered by the ceremonial counties of Gloucestershire to the north and Somerset to the south. Bristol is the most populous city in South West England. The wider Bristol Built-up Area is the eleventh most populous urban area in the United Kingdom. Iron Age hillforts and Roman villas were built near the confluence of the rivers Frome and Avon. Around the beginning of the 11th century, the settlement was known as (Old English: 'the place at the bridge'). Bristol received a royal charter in 1155 and was historically divided between Gloucestershire and Somerset until 1373 when it became a county corporate. From the 13th to the 18th century, Bristol was among the top three English cities, after London, in tax receipts. A major port, Bristol was a starting place for early voyages of exploration to the New World. On a ship out of Bristol in 1497, John Cabot, a Venetia ...

Trumpeter Swan Sasata
The trumpet is a brass instrument commonly used in classical and jazz ensembles. The trumpet group ranges from the piccolo trumpet—with the highest register in the brass family—to the bass trumpet, pitched one octave below the standard B or C trumpet. Trumpet-like instruments have historically been used as signaling devices in battle or hunting, with examples dating back to at least 1500 BC. They began to be used as musical instruments only in the late 14th or early 15th century. Trumpets are used in art music styles, for instance in orchestras, concert bands, and jazz ensembles, as well as in popular music. They are played by blowing air through nearly-closed lips (called the player's embouchure), producing a "buzzing" sound that starts a standing wave vibration in the air column inside the instrument. Since the late 15th century, trumpets have primarily been constructed of brass tubing, usually bent twice into a rounded rectangular shape. There are many distinct ty ...

IUCN Red List
The International Union for Conservation of Nature (IUCN) Red List of Threatened Species, also known as the IUCN Red List or Red Data Book, founded in 1964, is the world's most comprehensive inventory of the global conservation status of biological species. It uses a set of precise criteria to evaluate the extinction risk of thousands of species and subspecies. These criteria are relevant to all species and all regions of the world. With its strong scientific base, the IUCN Red List is recognized as the most authoritative guide to the status of biological diversity. A series of Regional Red Lists are produced by countries or organizations, which assess the risk of extinction to species within a political management unit. The aim of the IUCN Red List is to convey the urgency of conservation issues to the public and policy makers, as well as help the international community to reduce species extinction. According to IUCN the formally stated goals of the Red List are to provi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Endemism
Endemism is the state of a species being found in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can be also be referred to as an ''endemism'' or in scientific literature as an ''endemite''. For example '' Cytisus aeolicus'' is an endemite of the Italian flora. '' Adzharia renschi'' was once believed to be an endemite of the Caucasus, but it was later discovered to be a non-indigenous species from South America belonging to a different genus. The extreme opposite of an endemic species is one with a cosmopolitan distribution, having a global or widespread range. A rare alternative term for a species that is endemic is "precinctive", which applies to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Icterid
Icterids () or New World blackbirds make up a family, the Icteridae (), of small to medium-sized, often colorful, New World passerine birds. Most species have black as a predominant plumage color, often enlivened by yellow, orange, or red. The species in the family vary widely in size, shape, behavior, and coloration. The name, meaning "jaundiced ones" (from the prominent yellow feathers of many species) comes from the Ancient Greek ''ikteros'' via the Latin ''ictericus''. This group includes the New World blackbirds, New World orioles, the bobolink, meadowlarks, grackles, cowbirds, oropendolas, and caciques. Despite the similar names, the first groups are only distantly related to the Old World common blackbird (a thrush) or the Old World orioles. The Icteridae are not to be confused with the Icteriidae, a family created in 2017 and consisting of one species — the yellow-breasted chat (''Icteria virens''). Characteristics Most icterid species live in the tropics, although ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cardinal (bird)
Cardinalidae (often referred to as the "cardinal-grosbeaks" or simply the "cardinals") is a family of New World-endemic passerine birds that consists of cardinals, grosbeaks, and buntings. It also includes several birds such as the tanager-like ''Piranga'' and the warbler-like ''Granatellus''. As such, membership of this group is not easily defined by a single or even a set of physical characteristics, but instead by molecular work. In general they are medium to large songbirds with stout features, some with large heavy bills. Members of this group are beloved for their brilliant red, yellow, or blue plumages seen in many of the breeding males in this family. Most species are monogamous breeders that nest in open-cup nests, with many taking turn incubating the nest and taking care of their young. Most are arboreal species though the dickcissel is a ground-dwelling prairie bird. Conservation-wise most members of this family are considered least concern by the IUCN Red List tho ...
