 and eventually conditioning the progeny to return successfully to the wild. Establishment 

 of additional refuge areas in wintering range adjoining the Aransas Wildlife Refuge and 

 on St. Joseph and Matagorda Islands . Continuation of the publicity program to inform 

 the public on the current status of the cranes and the need for rigid protection at all 

 times . 



Number in captivity : Nineteen . 



Breeding potential in captivity : Very good.
