🦆Cackling Goose
シジュウカラガン (四十雀雁、Branta hutchinsii )は、カモ目カモ科コクガン属に分類される鳥類。全身がマガンより黒味を帯び、両頬が白く首の付け根に白い輪がある。和名はこの頬の模様がシジュウカラを連想させることに由来する。海洋の急峻な島嶼で繁殖する。 従来、カナダガン(学名:Branta canadensis)の亜種とされていたが、現在は別種となった。 2004 年、米国鳥学会(American Ornithologists' Union)は、カナダガンを二つの種に分類した。すなわち大型の亜種を Canada Goose(学名:Branta canadensis)に、亜種シジュウカラガンや亜種ヒメシジュウカラガンを含む小型亜種を Cackling Goose(学名:Branta hutchinsii)としてそれぞれ別種に分類した。日本でも日本鳥学会(Japanese Journal of Ornithology)が2012年の日本鳥類目録改訂第7版でこれを採用した。 なお、従来はカナダガン(学名:Branta canadensis)の亜種とされていたため、旧版の日本鳥類目録日本鳥学会では従来のBranta canadensisの種全体の種名と亜種Branta hutchinsii leucopareiaの両方に「シジュウカラガン」を使用していた。したがって、和名の使用には新旧の混乱があるので注意を要する。
