羽音

1. Origins, structure, and basic meaning

• Structure: 羽音 (はおと) combines wing 羽 and sound 音 to denote the sound of beating wings.
• Basic usage: It can come from a small insect outside a window or a bird taking flight.

2. Common pitfalls and similar expressions

• Wingbeat rather than a call
  • 羽音 is produced by wing movement through the air, not by the animal's voice.
