The tea tree duck can feed on the surface of the water, also can dive to feed under the water, and sometimes to the water to feed on the ground for grass. The food is mainly plant food such as rice, crop seedlings, grasses and aquatic plants, but also animal food such as insects, snails, mollusks, frogs and small fish. Tree ducks usually fly in groups of a few to a few dozen at dusk to feed in nearby rice paddies and return to their daytime waters before dawn.

The brown tree ducks stand upright when they rest, and often a few look around from time to time, and take off first when people or enemies are near, followed by other trees and ducks, and are extremely alert. Often in groups of a few to dozens of activities and foraging, there are many to hundreds of large groups. It is weak in flight and not as fast as other ducks.
