Mallard

Anas platyrhynchos

The Mallard is a type of dabbling duck feeding mainly on the surface rather than by diving. Dabbling ducks have feet centred on their body which makes it easy to walk on land. Males known as 'drakes' have glossy bluish-green heads. Females have brown heads. Both sexes have distinct white-bordered blue patches on their wings which become more noticeable in flight. The patches are known as 'speculum'. Early autumn drakes lose colour when moulting flight feathers to grow replacements. This process is known as the 'eclipse'. Mallards typically live 5-10 years spending time in and out of water. The most common collective nouns used for groups of Ducks and Mallards are 'Flock', 'Herd' and 'Badling'. Mallards eat vegetation, seeds, berries, insects and shellfish.

Mallards courting at Roe's well. The female acknowledged a head bobbing display by the drake by lowering her neck which he grabbed with his bill to pulled himself onto her back. A female can suffer neck injury and lose feathers if a male gets too rough, however in this case the coupling was over in a minute with no apparent bad consequences.

After hatching Mallard ducklings remain in the nest for at least 10 hours. This time is spent drying out and learning to use their legs. Leaving the nest for the first time they follow the female into the water. This is normally done early in the morning. The sooner the ducklings get into water to feed, the better their odds of survival. They cannot survive without their mother and it takes 50-60 days to fledge and become independent.

Bibbed Mallards are the result of selective breeding of domestic Mallards. They are not hybrids because they have been produced from birds of the same species. Other names used to describe these cross breeds include 'Manky Mallards' and 'Yuck Ducks'.
