context_page_description: This list of birds of Connecticut is a comprehensive account of all the bird species recorded from the U.S. state of Connecticut. Unless otherwise noted, this list is based on the checklist produced by the Avian Records Committee of Connecticut dated January 28, 2020, the list used by most birders to objectively evaluate species recorded in the state.
  This list includes all bird species known to have occurred in the state, including birds that don't breed in Connecticut, such as migrants, winter visitors and vagrants, as well as breeding species and recently extinct and extirpated species. There are about 280 species regularly occurring in the state. The Atlas of Breeding Birds of Connecticut listed 173 bird species as confirmed breeders, based on a 1982–1986 survey. An assessment before 2004 estimated the total number of species breeding regularly in the state at about 150.
  Of the 445 species listed here, 127 are considered rare or accidental. Eight were introduced to North America, three are extinct, and four have been extirpated. Ten species are included though they have only sight records.
