Featured Species

Wheeler National Wildlife Refuge provides excellent habitat for many species of native wildlife. A total of 300 species of birds, 47 species of mammals, 75 species of reptiles and amphibians, 115 species of fish, 38 species of freshwater mussels, and 26 species of freshwater snails have been documented on the refuge.

Sandhill Crane

Sandhill crane numbers are increasing at Wheeler NWR. Prior to 1997, Sandhill cranes occurred in small numbers on the refuge. In 1997, 26 Sandhill cranes were observed and by 2002 the number wintering on the refuge had increased to almost 400. In 2017/2018 the number peaked at 20,000. The cranes begin arriving in late November and numbers peak in early January. The best place to view them is from the Observation Building where they can be seen in large numbers feeding in the crop fields.

Whooping Crane

The Whooping Crane Eastern Partnership was formed in 1999 to restore a self-sustaining migratory population of whooping cranes in eastern North America. In January of 2006, two Whoopers from one of the Operation Migration cohorts were discovered on the refuge. Since then, Whooping Cranes have wintered each year on the refuge. During the winter of 2017-2018, up to 29 Whoopers spent a portion of their winter on the refuge. In recent years, they have frequented areas around the visitor center and wildlife observation building, allowing thousands of refuge visitors the opportunity to view them and learn their amazing story.
