I realize that there are some bird nuts on this forum, and so here is some information from the Calgary Zoo's latest quarterly newsletter. Whooping cranes are quite impressive looking birds, but apparently their wild population in 1945 dipped to only 21 individuals. With conservation programs and breeding grounds set up the overall number in the wild is now closer to 500. The Calgary Zoo as of 2008 has 25 whooping cranes, and has a single pair of birds (named Hope and Chinook) that have been responsible for 85 eggs in the past 11 years. Of those babies, 16 have been released back into the wild in Florida. It seems as if this single zoo has contributed to a substantial increase in the saving of a particular species of bird. The Calgary Zoo has a separate, 320 acre (129 hectare) area south of the city called the Devonian Wildlife Conservation Centre that breeds rare and endangered animals such as the whooping crane, Grevy's zebra, the mongolian wild horse, and Vancouver Island marmots.
