The Louisiana Department of Wildlife and Fisheries says 14 young whooping cranes are expected to arrive soon in southwest Louisiana.
That will double the number in a flock being reintroduced near the area where the state's last wild flock once lived.
Twenty-six whoopers have been brought to Louisiana, but predators and disease killed nearly half of them.
Biologists say deaths are expected, since the birds must learn to live in the wild. But teenage hunters killed two. The department is working to teach people why the birds need protection.
