context_page_description: 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. As of July 2020 there were 501 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.
  The OBRC Checklist divides the province into the Lowlands, Central, and South review zones and requests documentation of sightings of birds which are rare or accidental in one, two, or all of the zones. Of the 496 species on the list, 168 are noted as rare anywhere in the province and another 108 are rare in one or two of the zones. Eight species have been introduced to North America. One species has been extirpated, one is extinct, and another might be.
  This list is presented in the taxonomic sequence of the Check-list of North and Middle American Birds, 7th edition through the 61st Supplement, published by the American Ornithological Society.
