Mallard
Anas platyrhynchos
Overview
The Mallard is the most familiar duck in the world — the ancestor of most domestic ducks. Despite its familiarity, the drake in breeding plumage is a genuinely handsome bird: iridescent bottle-green head, yellow bill, chestnut breast and curled tail feathers. On the Sefton Coast, Mallards are present year-round on any open water from Marshside lagoons to dune slack pools. They're amber-listed in the UK due to declines in breeding populations, despite remaining common.

Frequently Asked Questions
Why is the Mallard amber-listed when it seems so common?
Despite remaining abundant, UK breeding Mallard populations have declined by around 30% since the 1970s, driven by wetland drainage, predation pressure and reduced water quality. The UK amber listing reflects this trend even though the overall population remains very large.
