More facts about the migratory animals
The Siberian Cranes nest in western Siberia and migrate to India. Their plumage is pure white, except for some wing feathers, which are black. The eastern populations migrate during winter to China while the western population migrates in Iran, India and Nepal during winter.
Salmon migrate from the Pacific Ocean or the Atlantic Ocean to the rivers where they are born every year. If calculated, the journey made by salmon can reach more than 1,000 kilometers. Many scientists say that the salmon migration is the heaviest migration in the animal kingdom.
Killer whales migrate up to 7,000 miles roundtrip. Their skin is often colored with a yellow algae (海藻). Scientists think they swim to warmer water to slough off dead skin cells. Even killer whales need a little spa treatment now and then.
