Flocks of sandhill cranes passed over Chicago yesterday during their fall migration, filling the air with their raspy, raucous calls. As some of the largest birds in North America and with some of the widest wingspans of all the birds on the North American continent their migration is particularly striking. To learn more about sandhill cranes, check out some of the resources available from the web and in the Library.

Among the thousands of sandhill cranes seen over Chicago yesterday, observers also reported seeing a few whooping cranes, an endangered species. Efforts are underway to re-establish a migratory flock of these birds.
