Brief Description
A small, chunky diving duck with a distinctive ponytail-like tuft on the back of its head. They are active swimmers and frequent divers.
Additional Information
- Region of Origin: Palearctic (Europe and Asia)
- Typical Sighting Period: Year-round in temperate Europe; winter visitor in southern regions
- Plumage Details: Adult males are black with white flanks and a distinct pendant crest (tuft). Females are dark brown with paler flanks and a smaller tuft. Breeding plumage is most vibrant in late winter and spring.
- Ecological Significance: Controls populations of aquatic invertebrates and helps in the dispersal of aquatic plant seeds.
- Conservation Status: Least Concern (Population stable)
- Observation Tips: Look for them in deep city park ponds or reservoirs; they are less shy than other diving ducks and can often be seen diving repeatedly in the middle of water bodies.
Size & Weight
Length: 40-47 cm; Wingspan: 67-73 cm; Weight: 600-1000 g

Omnivorous, primarily consuming mollusks (especially zebra mussels), aquatic insects, and some plant material by diving.
Habitat
Prefer open water with moderate depth, including lakes, reservoirs, ponds, marshes, and occasionally slow-moving rivers.
Migration
Migratory in the north and east; resident or short-distance migrant in temperate western and southern Europe.
Voice (Call & Song)
Generally silent, but males give a soft whistle 'wi-oo' and females a growling 'kar' during courtship.

Interesting Facts
The Tufted Duck has greatly expanded its range in Europe over the last century, partly due to the spread of the invasive Zebra Mussel, which is one of its favorite food sources.
