Diet
Seeds, water plants, insects and snails; dabbles or upends in shallows; bread is poor food.
Habitat
Ponds, canals, rivers, lakes and wet meadows; almost any water.
Breeding
Nests on the ground under cover from March; usually 11–14 eggs in a single brood; ducklings leave the nest a day after hatching and feed themselves.
Field signs
- Loud 'quack-quack' from females; drakes make soft rasping whistles
- Flat nest of grass and down under a shrub, often far from water
- Drake in summer 'eclipse' plumage looks like the female
Did you know?
- Only the female mallard quacks; drakes whistle and rasp.
- Most domestic ducks, except Muscovies, descend from the mallard.
- After breeding, drakes moult all their flight feathers at once and cannot fly for around three to four weeks in summer.
Moments worth waiting for
- Ducklings in a line
A mallard leads a line of fluffy ducklings across the canal, one straggler paddling to catch up. - Upending
A drake tips up bottom-first to graze the pondweed, tail wagging.
Photo tip
Take low-angle photographs from the water's edge with the sun behind you to get the green shine of the drake's head. Ducklings are best on a calm, overcast morning in May.
Be a good naturalist
Do not feed bread: it fills them with junk and pollutes water. Use oats or chopped greens sparingly. Never pick up ducklings; the mother returns.
The law
All wild birds, their nests and eggs are protected under the Wildlife and Countryside Act 1981; it is an offence to kill, injure or take them or damage an active nest.
