  • Mallard duck

    Anas platyrhynchos

    Mallards occur in various forms and colours. The males are very recognisable with their iridescent bottle green head and neck and the narrow white ring around the base of the neck and their chestnut breast. Distinctive characteristics include orange legs and their tail feathers curl upwards. Non-breeding plumage of males resembles that of the female of being brown with darker spots and stripes. Females have a grey bill and purple speculum and orange legs.

    Mallards also occur in white or variants of the green head as a result of inbreeding. To keep pure bred Mallards you need to have a permit, while all hybrids are classed as Category 1a.
