- Risiko rendah
Sleek fish-eater with a serrated bill. Ferries chicks downstream on her back in single file.
- Populasi
- Approx. 1,700,000–2,400,000 mature individuals globally; European population component ~134,000–206,000 mature individuals (66,800–103,000 pairs).
- Habitat
- Clear, fast-flowing rivers and large lakes in forested landscapes for breeding (nests in tree cavities); shifts to large lakes, big rivers, reservoirs, and sheltered coastal/estuarine waters in winter.
- Fakta menarik
- Female Common Mergansers sometimes form 'crèches' by combining broods, with one female recorded tending more than 70 ducklings at once.
- Sebaran
- Holarctic distribution — breeds across northern North America (Alaska/Canada south into the northern contiguous US), and across northern Europe and Asia (including Scandinavia, the UK, and Siberia); northern populations migrate south to temperate latitudes for winter, while some populations are resident year-round.
- Makanan
- Primarily fish, caught by diving and gripped with a long, narrow, serrated ('sawbill') bill; also takes mollusks, crustaceans, worms, aquatic insect larvae, amphibians, and occasionally small mammals or birds. Ducklings start on aquatic insects before shifting to fish around 12 days old.
