White Swan
The white swan is also called whooper swan. It can grow up to 1.5 m high and about 6 kg. It has long necks, nearly half of the body length. They usually stretch their necks when they are swimming with their two wings closed. From ancient to modern times, the white swan has been regarded as the symbol of purity and honest because of their graceful and elegant posture. The swan usually eats the seeds, rhizomes and leaves of water plants as well as the seeds of weeds, and pecks few mollusks, aquatic insects, earthworms, etc. It has a big mouth good at finding food. It can dig out the food 0.5 m under the sludge. The swan is a symbol of “Loyal Love”, and it is monogamous. They forage or rest in pairs. The female swan usually lays two or three eggs in May every year. Then the female swan broods the eggs while the male swan guards around. They will flap their wings to fight against the enemy bravely when they facing the hostile animals. They stay in pairs and help each other during the breeding period. Moreover, if one of the couple died, the other will “preserve chastity” and live a lonely life to death.
