chaffinch
A small European finch (Fringilla coelebs) with a distinctive song. The Japanese name literally means 'blue-headed bunting', referring to the male's blue-grey crown.
I heard the song of a chaffinch in the park.
Standard katakana spelling for this bird name.
Kanji spelling is rare and mainly used in ornithological contexts; the word is usually written in kana.
The Japanese name 頭青花鶏 (zu-ao-atori) is a compound of 頭 (zu, 'head'), 青 (ao, 'blue'), and 花鶏 (atori, 'brambling'), describing the male's blue-grey head. The word is a calque or descriptive coinage for the European chaffinch.
