1967 the flock had 48 birds. Cranes
normally lay two eggs, but it is rare to raise two chicks. Scientists
began taking one of the eggs from a few whooper nests, leaving
for the birds to hatch. They took six eggs in all.
took the eggs to a special place to be hatched. The plan was
a captive flock of Whooping Cranes. Those cranes
would lay more eggs that could be released back into the wild.
This would help grow
the endangered Aransas/Wood Buffalo flock — the world's
only natural wild Whooping crane flock.
