In short

The most reliable field mark is the overall shape and plumage contrast: Tufted Duck males are strikingly black-and-white with a prominent head tuft, while Eurasian Teal males are much smaller, with a chestnut head and green face patch, and both sexes show a green speculum in flight. Juvenile and female Teal are mottled brown and tiny, with a compact, dabbling duck shape, whereas Tufted Duck females are larger, darker brown, and show a more rounded diving duck profile. In flight, Teal of all ages show a bright green speculum bordered by white, while Tufted Ducks have a white wing stripe on the secondaries but lack green. Structure and size are also key: Teal are notably smaller and more delicate, with a short bill and tail, while Tufted Ducks are bulkier, with a longer, blue-grey bill and, in males, a distinctive head tuft.

Identification tips

  1. Size and shape: Teal are much smaller and more compact than Tufted Ducks. If you see a tiny duck among other species, suspect Teal. Tufted Ducks are noticeably bulkier, with a rounder head and longer neck.
  2. Flight pattern (all ages): Teal show a bright green speculum bordered by white on the upperwing, visible in all ages and sexes. Tufted Ducks show a white wing stripe across the secondaries but never any green. This is a key flight mark.
  3. Bill shape and color: Teal have a short, dark grey bill (females/immatures may have a pinkish or yellowish base). Tufted Ducks have a longer, blue-grey bill with a black tip, easily seen at close range.
  4. Head tuft: Adult male Tufted Ducks have a long, drooping black tuft at the back of the head, visible even at a distance. Teal never show a head tuft. Female Tufted Ducks may show a shorter tuft, but it's always absent in Teal.
  5. Male plumage: Breeding male Teal have a chestnut head with a bold green face patch and a thin yellowish-white border, a white horizontal side-stripe, and a yellowish triangle at the tail. Male Tufted Ducks are black with white flanks and a blue-grey bill, lacking any chestnut or green on the head.
  6. Female/immature plumage: Female and immature Teal are mottled yellowish-brown with a dark eye-stripe and scaly body pattern. Female Tufted Ducks are dark brown with paler flanks, sometimes with a white patch at the bill base, but never show the green speculum of Teal.
  7. Underwing: Teal have a whitish underwing with grey remiges and dense dark spotting on the inner coverts, plus a dark leading edge. Tufted Duck underwing is less distinctive, mostly pale with a white stripe.
  8. Tail and rump: Teal show a bright yellowish-buff triangular patch at the sides of the tail coverts (males), and both sexes have a short tail. Tufted Ducks have a longer tail and lack any yellowish patch.
  9. Behavior: Teal dabble and tip up; Tufted Ducks dive. If you see a duck repeatedly diving and staying submerged, it's almost certainly a Tufted Duck.
  10. Habitat: Teal favor shallow, muddy wetlands and marshes; Tufted Ducks prefer deeper lakes and reservoirs. Context can help, but beware overlap in winter.
  11. Vocalizations: Teal are much more vocal, especially in flocks, with clear whistled calls. Tufted Duck females give a harsh "karr" in flight; males are mostly silent.
  12. Iris color: Tufted Ducks have striking golden-yellow eyes (adults), while Teal have brown eyes in all ages and sexes.
  13. Eclipse plumage: Male Teal in eclipse look like females but are darker above; male Tufted Ducks retain their black-and-white pattern but may have a duller tuft.
  14. Pitfalls: Female Tufted Ducks with a white bill base patch can be confused with scaup species, but never with Teal, which are much smaller and lack any white at the bill base.
  15. Flock structure: Teal often form tight, fast-moving flocks; Tufted Ducks are more scattered and less agile in flight.

Size

Eurasian Teal is one of the smallest dabbling ducks, measuring 34–43 cm in length with a wingspan of 53–59 cm and an average weight around 340–360 g [wikipedia]. Tufted Duck is larger and more robust, though exact measurements are not provided here, but it is consistently bulkier and longer-necked than Teal. In the field, Teal will look noticeably daintier and more compact, especially when seen side by side with Tufted Duck.

Plumage

Juvenile and female Teal are mottled yellowish-brown with a dark eye-stripe and scaly body pattern, always with a green speculum bordered by white in flight. Immature Teal resemble adult females but with stronger patterning. Adult male Teal in breeding plumage have a chestnut head with a bold green face patch, a white horizontal side-stripe, and a yellowish triangle at the tail sides. In eclipse, males resemble females but are darker above. Tufted Duck adult males are glossy black with bright white flanks, a blue-grey bill, golden-yellow eyes, and a long, drooping head tuft. Females are dark brown with paler flanks, sometimes with a white patch at the bill base, and lack the green speculum. In flight, Tufted Ducks show a white wing stripe across the secondaries but no green. The head tuft is always visible on males and sometimes faintly on females. Teal never show a tuft, and their upperwing pattern is diagnostic: a green speculum with white borders, visible in all ages and sexes.

Behaviour

Eurasian Teal are dabbling ducks, feeding mostly at the surface or tipping up in shallow water. They are quick, agile fliers and often flush in tight flocks. Tufted Ducks are diving ducks, frequently seen diving for food and spending more time submerged. Their takeoff is more labored, and they sit lower in the water than Teal. Teal are more likely to be seen in small, shallow wetlands, while Tufted Ducks prefer deeper lakes and reservoirs.

Habitat

Both species can overlap in winter, but Eurasian Teal are most common in shallow wetlands, marshes, and flooded fields, often in large flocks. Tufted Ducks are more often found on deeper lakes, reservoirs, and slow rivers. If you see a small duck in a shallow, muddy pool, it's more likely to be a Teal; a black-and-white duck on a deep lake is more likely to be a Tufted Duck.

Voice

Male Teal are notably vocal, giving a clear, whistled "cryc" or "creelycc". Females give a soft "keh" or "neeh" quack. Tufted Duck males are mostly silent except for a simple "wit-oo" whistle during courtship; females give a harsh, growling "karr," especially in flight. Teal are generally louder and more vocal in flocks than Tufted Ducks.
