ruddy shelduck
A species of waterfowl (Tadorna ferruginea). The name is typically written in katakana.
アカツクシガモは日本ではまれな冬鳥です。
The ruddy shelduck is a rare winter bird in Japan.
The name combines アカ (red), ツクシ (an old name for the Chikushi region, now part of Fukuoka), and ガモ (duck). The exact origin of the name is uncertain, but it likely refers to the bird's reddish plumage and a historical association with that area.
