hybridisation that occurs among wild ducks complicates efforts to tease apart the relationships between various species.
![Mallard drake](https://upload.wikimedia.org/wikipedia/commons/5/54/Mallard_drake_.02.jpg)
In most modern classifications, the so-called 'true ducks' belong to the subfamily Anatinae, which is further split into a varying number of tribes. The largest of these, the Anatini, contains the 'dabbling' or 'river' ducks – named for their method of feeding primarily at the surface of fresh water. The 'diving ducks', also named for their primary feeding method, make up the tribe Aythyini. The 'sea ducks' of the tribe Mergini are diving ducks which specialise on fish and shellfish and spend a majority of their lives in saltwater. The tribe Oxyurini contains the 'stifftails', diving ducks notable for their small size and stiff, upright tails.
A number of other species called ducks are not considered to be 'true ducks', and are typically placed in other subfamilies or tribes. The

Morphology
