How to identify

The Mallard is a large and heavy-looking duck. It has a long body, and a long and broad bill. The male has a dark green head, a yellow bill, is mainly purple-brown on the breast and grey on the body. The female is mainly brown with an orange bill. Mallards breed in all parts of the UK in summer and winter, wherever there are suitable wetland habitats, although it is rarer in upland areas. In the UK, Mallards may be resident breeders or migrants – many of the birds that breed in Iceland and northern Europe spend the winter here.

Behaviour

At the tail-feather-end of spring, the breeding season blends seamlessly into a race to rear young, and family favourite the Mallard, is no exception. Mallards can breed in suitable weather from February, but June is best for spotting fluffy ducklings.

Mallard mothers can be seen proudly promenading up to 13 adorable ducklings on bodies of fresh water across the UK. During this time, she alone will raise them, offering protection and teaching them all they need to know to strike out on their own.
