Morphology
The compound is directly compositional: 'whistling' (producing a whistle sound) modifies 'buoy' (an anchored floating marker), so a buoy that emits a whistling sound is immediately inferable. This present‑participle adjective + noun pattern is a regular, cross‑linguistic construction, making the meaning accessible to a B1 learner who knows both words.
Etymology
The noun whistling buoy comes from a simple picture: a floating buoy that makes a high whistling sound when wind or waves pass through a small pipe, so sailors can hear it in fog. That's why a whistling buoy means 'a floating marker that makes a whistle to warn or guide ships'.
