noun
mourning dove
Refers specifically to the North American species Zenaida macroura; not a general term for doves.
庭にナゲキバトが来て、静かに鳴いていた。
A mourning dove came to the garden and was cooing softly.
ハト is the general term for pigeons and doves; ナゲキバト is a specific species.
The Japanese name ナゲキバト is a calque of the English 'mourning dove', combining 嘆き (なげき, 'mourning') and 鳩 (はと, 'dove').
