WHOOPING

CRANE
Named for its whooping sound, the whooping crane is the tallest North American
bird. An adult whooping crane is white with a red crown and a long, dark, pointed
bill. However, immature whooping cranes are cinnamon brown. While in flight,
their long necks are kept straight and their long dark legs trail behind. Adult
whooping cranes' black wing tips are visible during flight. Their lifespan is
estimated to be 22 to 24 years in the wild.
After being pushed to the brink of extinction by unregulated hunting and loss of
habitat to just 21 wild and two captive whooping cranes by 1941. The total number
of cranes in the surviving migratory population, plus three reintroduced flocks and
in captivity, now exceeds 800 birds.
Scientists found that although cranes lay two eggs, only one chick hatches.
Apparently, American cranes are not able to feed two chicks at once. So people
started collecting eggs and laying them on other birds. The chicks were raised in
captivity.
