Tufted Duck Identification Guide

Key Field Marks

• Size & shape: A small, compact diving duck (Aythya genus) with a rounded head, a distinctive drooping tuft of feathers at the back of the crown (longer in males, shorter in females), and a fairly short, broad bill with a black nail tip.
• Male plumage: Striking black overall with clean, bright white flanks, a glossy purplish-black head, and a vivid golden-yellow eye — one of the most contrastingly patterned diving ducks in its range.
• Female plumage: Dark brown overall with paler, dusky-brown (not white) flanks, a smaller head tuft, and sometimes a small whitish patch at the base of the bill (which can suggest scaup, requiring care).
• In flight: Shows a bold white wing stripe running along the length of both the secondaries and primaries — broader/more extensive than the wing stripe of scaup.
• Behavior: An active diver, feeding on aquatic invertebrates (notably mollusks) and vegetation by diving from the surface; often forms large rafts on lakes and reservoirs, frequently mixing with scaup and Pochard.

Separating Tufted Duck from Similar Species

• Greater and Lesser Scaup: Lack any head tuft, have a more rounded (Greater) or peaked (Lesser) head shape without a drooping crest, and show gray (not white) backs on males — Tufted Duck's male has a solidly black back, contrasting with scaups' pale gray back.
• Ring-necked Duck (North America): Has a peaked, angular head shape (no tuft), a bold white ring near the bill tip and a subtler pale ring at the base, and a gray (not white) flank with a pale wedge in front of the wing on the male — Tufted Duck shows uniformly white flanks and no bill rings.
• Ferruginous Duck: Smaller, rich chestnut-brown overall with a white eye (male) and white undertail patch, entirely different from Tufted Duck's black-and-white pattern.
• Female Tufted Duck vs. female scaup: Both can show a whitish face patch, but female Tufted Duck retains a small head tuft and has darker, more uniformly brown flanks compared to the grayer-brown flanks of female scaup.

Where & When to See It

Breeds across a broad swath of Europe and northern/central Asia on lakes, reservoirs, and slow rivers with emergent vegetation. Highly migratory in the northern parts of its range, wintering on lakes, reservoirs, coastal bays, and estuaries across western and southern Europe, the Mediterranean, the Middle East, and South and East Asia; a regular winter visitor and increasingly regular vagrant to North America, especially in the Northeast and along the Pacific coast, often found associating with scaup flocks.

Voice

Generally quiet outside the breeding season; males give soft wheezy or whistling courtship notes during display, while females utter a harsh, growling "karr" or "krrr," mainly around the nest or when alarmed.
