A British colloquial name for the red-breasted merganser (Mergus serrator), a diving duck with a serrated bill adapted for gripping fish. The 'saw' in the name refers directly to the tooth-like serrations along the edges of the beak, a useful anatomical identifier. Sawbill is also applied more broadly to other merganser species. Common enough in birdwatching circles as an informal alternative to the full name.
A sawbill was working the current near the weir, diving repeatedly and coming up empty.
Origin: Descriptive compound: 'saw' (serrated edge) + 'bill' (beak). A folk name based on the bird's most distinctive physical feature. Editorial expansion authored on Slangora.
