Appearance characteristics Red-crowned crane has the characteristics of cranes, that is, three lengths-long mouth, long neck and long legs. Adult birds are all white except the neck and the back end of flight feathers, and the skin on the top of their heads is bare and bright red. The legendary poisonous crane top red (also known as crane top blood) is here, but it is purely a rumor that crane top blood is nontoxic. What the ancients called "crane top red" is actually arsenic, which is impure arsenic trioxide. Hedinghong is an obscure statement about arsenic in ancient times. The fat glands on the tail of red-crowned crane are covered with powder (natural feathers). Young birds have brown feathers and a yellow beak. The feather color of the sub-adult is dim, and the red color of the exposed area on the top of the head becomes more vivid after 2 years old.
