Mallard

Anas platyrhynchos

Birb mood: the park-pond classic

The familiar green-headed dabbling duck of ponds worldwide — and the wild ancestor of nearly every farmyard duck.

Also known as: Wild Duck, Greenhead (drake)

What's in a name? Anas is simply Latin for "duck"; platyrhynchos comes from Greek for "broad-billed", describing the wide, flat dabbling bill.

How to identify

Main colours Brown Green Grey

Drakes: glossy green head, white neck-ring, chestnut breast, grey body and a curled black central tail feather. Both sexes show a blue speculum bordered with white on the wing.

Male vs female

The drake is unmistakable in breeding plumage; the hen is mottled brown for camouflage, with an orange-and-brown bill and the same blue wing patch.

Juvenile appearance

Ducklings are classic yellow-and-brown fluffballs; juveniles resemble the female before young drakes develop their green heads.

Breeding vs non-breeding

Breeding drakes show the green head and grey body; in late-summer eclipse plumage males become dull and female-like (told by the yellow bill) before regaining breeding colours.

Biology & behaviour

Diet

An opportunistic omnivore: seeds, aquatic plants, insects, snails and the occasional small fish, gathered by dabbling at the surface and upending in shallow water.

Behaviour

Social and noisy in winter flocks. After breeding, drakes moult into a drab "eclipse" plumage and briefly lose the power of flight while replacing their wing feathers.

Breeding

The female nests on the ground near water, lines the nest with her own down, and leads the precocial ducklings to water within a day of hatching.

Migration

Northern populations migrate to escape ice; many temperate and urban birds are year-round residents wherever water stays open.

Population trend: Stable

The Mallard is the duck most of us learned to recognise first: the drake’s bottle-green head and yellow bill against the female’s mottled brown camouflage, both upending in the shallows to feed. It is one of the most abundant and adaptable waterfowl on the planet, equally at ease on a wild marsh or a city park lake.Its success is also its complication: Mallards interbreed readily with other ducks and are the ancestor of almost all domestic duck breeds. Watching a pair “dabble” — tails up, heads down, sieving the muddy shallows — is a perfect first lesson in how ducks actually feed.
