🦆 Mallard — Species ID Dossier

A 4-card field-ID dossier for the Mallard (Anas platyrhynchos), Episode 7 of 59. Covers the iconic iridescent-green-headed male with female inset, a dorsal/ventral flight-view card highlighting the diagnostic blue-purple speculum, a call card distinguishing the female's descending KWAK series from the male's soft rasp, and a four-panel look-alike comparison against American Black Duck, Mottled Duck, and Gadwall.

Anas platyrhynchos · Episode 7 of 59
That green head isn't just green — it shifts from emerald to teal depending on the angle of light. The Mallard is so common it becomes invisible, but look closer and there's a genuinely spectacular duck hiding in plain sight.
Swipe through all four cards for the full field-ID picture: plumage marks, flight pattern, the call that literally defined "duck," and three look-alikes that trip up even experienced birders.
Card 1 — Perched portrait Male Mallard: iridescent green head, yellow bill, white neck ring, chestnut breast, gray body, curled black tail feathers, orange feet. Blue-purple speculum visible on the folded wing. Female inset: warm mottled brown, orange-and-black bill.
Body length 23 in (58 cm) · Wingspan 35 in (89 cm) · Weight 2.4 lb (1.1 kg)
Card 2 — Flight view Dorsal: the blue-purple speculum flanked by clean white bars is the diagnostic mark — visible at distance. Ventral: stark white underwing linings contrast sharply with dark flight feathers. Broad, powerful wings; neck outstretched; orange feet tucked behind the tail.
Card 3 — Calls The female owns the quack everyone knows — a loud, classic descending series: KWAK-kwak-kwak-kwak-kwak (dropping in both pitch and volume). The male? A soft, reedy rasp: rrebb-rrebb — more rusty hinge than "duck."
Mnemonic → Female: LOUD then fading, her domain · Male: soft rasping creak
Card 4 — Look-alikes Three species that cause real ID confusion:
  • American Black Duck — dark chocolate-brown all over (no green head on males), violet speculum bordered narrowly in black instead of white, orange-red feet
  • Mottled Duck — like a female Mallard but darker, with a clean buffy face contrasting a dark cap, green (not blue-purple) speculum; Gulf Coast and Florida only
  • Gadwall — male has intricate gray scalloped body, distinctive white speculum (unique among dabbling ducks), and a bold black rump
Year-round across North America — pond edges, park lakes, rivers, marshes. The bird that taught most of us what a duck is.
