The Calgary Zoo has received a conservation award for its working to protect the endangered whooping crane.
The North American Conservative Award is handed out annually by the U.S. based Association of Zoos and Aquariums.
The Calgary Zoo is being recognized along with the International Crane Foundation, the San Antonio Zoo and the Audubon Nature Institute.
The association says award recipients have helped the birds recover by breeding them, protecting key habitat and engaging the public in protection efforts.
In 1944 just 21 whooping cranes were left in the wild, but conservation efforts have seen the number climb to about 450.
