Whooping cranes (Grus americana) [Figs. 1 and 2] are the rarest, most endangered cranes in the world. They numbered only 22 birds in 1937, and their breeding grounds were not discovered until 1954. The status of the whooping crane population was instrumental in the enactment of the Endangered Species Act of 1973 in the United States. From these low numbers in the 1930s and 1940s, conservation and captive breeding efforts have increased their numbers to more than 550 whooping cranes today. Half of these whooping cranes are in the historic wild flock that migrates between the Texas Gulf Coast (in the United States) and northern Alberta (in Canada).
