lower pitch, longer quack than the hen mallard. This call is often used while feeding and when a mallard drake is landing. It gives the other birds a heads up. The quack of a mallard drake requires voice and is replicated by humming into a special whistle-like call. In teals, the drakes make a call of short bursts of a high pitch whistle. The "teet! (pause) teet! (pause) teet!-teet!" or any other order of repetition. This call can be made by blowing short bursts of air into the whistle. The majority of duck sounds such as quacking people have heard and are familiar with comes from female, or hen, mallards. Hen mallards are extremely vocal and this is probably why the number one call for duck hunting in North America is a hen mallard call. By making your call sound similar to that of a hen mallard, almost all other ducks will respond to it, and have their curiosity piqued by the calling.
