Diet & feeding

Omnivorous — seeds, aquatic plants, insects, snails, amphibians and even small fish, often up-ending in shallow water.

Dabbling (tips up, tail in the air) Medium (mallard-sized, 45–55 cm)

Habitat

Almost anywhere with water: park ponds, lakes, rivers, estuaries, flooded fields and city canals.

Breeding

Nests on the ground near water, often hidden in reeds. Ducklings leap from the nest within a day of hatching.

Migration

Largely sedentary; northern European birds boost the population in winter.

Vocalisation

The classic female "quack"; males give a softer, rasping call.
