The Mallard Duck (Anas platyrhynchos) is a common dabbling duck found in Georgia. The male mallard is unmistakable with a glossy green head. The female is predominantly colored mottled brown.
In Trinity Lakes, the mallards enjoy feeding on the sedges surrounding the lakes and acorns from the oak trees. The average life expectancy is three years, but they can live to twenty.
The predation-avoidance behavior of sleeping with one eye open, allowing one brain hemisphere to remain aware while the other half sleeps, was first demonstrated in mallards, although it is believed to be widespread among birds in general.
