The avifauna of the Aleutian Islands included 376 species according to Gibson and Byrd (2007), ''Bird Checklists of the World'' (Avibase), and the American Ornithological Society (AOS) as of March 2021. Of them, 44 (12%) are year-round residents and breeders, 26 (7%) migrate to the Aleutians to breed, 18 (5%) migrate to the Aleutians to winter, 6 (2%) are non-breeding summer residents, 37 (10%) are annual through-migrants, 196 (53%) are vagrancy (biology), vagrants of less-than-annual occurrence. The status of the remaining 42 is not noted by either Gibson and Byrd or Avibase. Several of the vagrants have only a single record. This list is presented in the taxonomic sequence of the ''Check-list of North and Middle American Birds'', 7th edition through the 62nd Supplement, published by the 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. The following terms are used to denote the annual and seasonal status of each species reported by Gibson and Byrd (2007), or in the case of "Accidental", noted as such for species added from Avibase: *Accidental (biology), Accidental – one or two records *Casual – recorded in <30% of years in the appropriate season, but in at least three calendar years *Intermittent – recorded in ≥30% of years in the appropriate season, but not annually *Migrant – annual through-migrant in spring or fall *Resident – substantial numbers present throughout the year *Summer – migrates to the Aleutians to breed or to summer offshore *Winter – migrates to the Aleutians to winter *Annual breeders are designated with an asterisk (*), as in Resident* or Summer*.
