common nighthawk (Chordeiles minor)
A nocturnal bird of the nightjar family found in the Americas. The Japanese name is a direct borrowing from English 'nighthawk' with the prefix アメリカ.
The common nighthawk becomes active at dusk.
Kanji spelling exists but is rarely used; the bird name is normally written in kana.
From アメリカ (America) + ヨタカ (nightjar). The word is a calque of the English 'common nighthawk'.
