Ecology and Behavior
Though not much is known about this shelduck, it is believed to be migratory, traveling from Siberia in the breeding season to Korea, southern Russia, and Japan for the winter. The Crested Shelduck is believed to eat aquatic vegetation, agricultural crops, algae, invertebrates, mollusks, crustaceans, carrion, and garbage. It has been suggested that this shelduck may be a nocturnal feeder. While its nest has not been described, similar shelducks nest in burrows and cavities; it has also been suggested that this species may nest in tree cavities. It has been proposed that this species lays less than ten eggs which the female alone incubates. It is believed to breed from May to July. The shelduck has been observed in flocks of two to eight birds.

Famous quotes containing the words ecology and/or behavior:
“... the fundamental principles of ecology govern our lives wherever we live, and ... we must wake up to this fact or be lost.”
—Karin Sheldon (b. c. 1945)
“He is not a true man of science who does not bring some sympathy to his studies, and expect to learn something by behavior as well as by application. It is childish to rest in the discovery of mere coincidences, or of partial and extraneous laws. The study of geometry is a petty and idle exercise of the mind, if it is applied to no larger system than the starry one.”
—Henry David Thoreau (1817–1862)
