The Aleutian Canada goose is a subspecies of the Canada goose that breeds in the Aleutian Islands.
カナダガン is the general term for the Canada goose species (Branta canadensis), while シジュウカラガン refers specifically to the Aleutian subspecies.
Katakana spelling is standard for this bird name; usually written in kana.
Kanji spelling is rare and may not be widely recognized; the katakana form is strongly preferred.
The name シジュウカラガン is a combination of 四十雀 (しじゅうから, 'great tit') and 雁 (がん, 'wild goose'), possibly from a perceived resemblance to the great tit in some feature, though the exact derivation is uncertain.
