This list of birds of Ontario includes all the bird species recorded in the Canadian province of Ontario as determined by the Ontario Bird Records Committee (OBRC). There are, as of 2008, 478 species on this list, 291 of which are known to breed in the province. Ontario has a considerable variety of bird species. One of the factors in this diversity is the size and range of environments in Ontario. Another is the Great Lakes, many birds use the shores as a stopping point during migration. Several common birds in Ontario, such as the house sparrow, the rock dove, the European starling and the mute swan are introduced species, meaning that they are not native to this continent but were brought here by humans from Europe or elsewhere.〔 This list is presented in taxonomic order and follows ''The Check-list of North American Birds'', published by the American Ornithologists' Union. The table of contents is grouped into passerines (the largest order of birds) and non-passerines. The family accounts at the beginning of each heading reflect this taxonomy, as do the species counts found in each family account. ==Taxonomy== The taxonomic treatment (designation and sequence of orders, families and species) and nomenclature (common and scientific names) used in the accompanying bird lists adhere to the conventions of the AOU's (1998) ''Check-list of North American Birds'', the recognized scientific authority on the taxonomy and nomenclature of North America birds. The AOU's Committee on Classification and Nomenclature, the body responsible for maintaining and updating the ''Check-list'', "strongly and unanimously continues to endorse the biological species concept (BSC), in which species are considered to be genetically cohesive groups of populations that are reproductively isolated from other such groups" (AOU 1998). See Sibley-Ahlquist taxonomy for an alternative phylogenetic arrangement based on DNA-DNA hybridization. Unless otherwise noted, all species listed below are considered to occur regularly in North America as permanent residents, summer or winter residents or visitors, or migrants. The following codes are used to designate some species: *(A) Accidental - occurrence based on one or two (rarely more) records and unlikely to occur regularly *(I) Introduced - established solely as result of direct or indirect human intervention; synonymous with non-native and non-indigenous *(E) Extinct – a recent species that no longer exists *(Ex) Extirpated – a species that no longer occurs in Ontario, but populations still exist elsewhere __NOTOC__ 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「List of birds of Ontario」の詳細全文を読む スポンサード リンク
