Diet / Feeding:
Teals usually feed by dabbling, upending (feeding upside down in water) or grazing on land. They may submerge the head and on occasion even dive to reach food. In the breeding season, they eat mainly aquatic invertebrates, such as crustaceans, insects and their larvae, mollusks and worms.
In winter, they shift to a largely granivorous diet, feeding on seeds of aquatic plants and grasses, including sedges and grains.
Diurnal throughout the breeding season, in winter they are often crepuscular or even nocturnal feeders.
