The Grey Crested or Crown Crane is the national bird of Uganda, adorning their flag. “They are considered to be ‘living fossils’ among cranes, having flourished in the Eocene period some 54 to 38 million years ago and surviving the ice age. During their mating dance, two cranes hop and jump gracefully with each other, their wings partly spread. Then they open their wings fully, bow to each other, and jump several feet in the air. When they land, they run around each other and start all over again.” Read more from SwitchZoo here.
