Waterfowl numbers begin to decline rapidly. Wood duck nesting begins. Depending on weather, fishing can be good by the end of the month.
Waterfowl numbers are low, but variety of species can still be seen. Blue-winged teal and shorebirds begin migrating. Turtles are present on sunny days. Crappie fishing is at its best.
Teal migration is at its peak. Warblers, vireos, and other small passerine birds are migrating. Migrant songbird nesting is in full progress. Wildflowers are at their peak.
Broods of wood ducks, mallards, and black ducks appear. Young songbirds and rabbits begin to appear. The last of the migrant songbirds are moving through the refuge.
With migration at an end, only resident birds and mammals are seen. Fishing for bluegill and bass is fairly good. July waterfowl activity is at its lowest ebb of the year. Songbird young are common in woods and fields.
The fall migration of songbirds begins with purple martins bunching for their southward move. Large numbers of swallows move through and some early shorebird migration begins. A few blue-winged teal begin arriving. Fishing for catfish is good.
Blue-winged teal migration is at its peak. Shorebirds and large numbers of swallows begin moving through. The first incoming geese arrive during the latter part of the month.
Sport fishing is good. Waterfowl continue to arrive with good concentrations present by the end of the month. The mass of southward bound fall songbird migration is at its peak.
Although songbird migration is at its end, waterfowl and crane numbers continue to increase. Large numbers of great blue herons can be seen congregating. Red-tailed and marsh hawks along with raptors are common.
Waterfowl and crane numbers reach their peak during the latter part of the month. Bald and golden eagles, although not common, may be present.
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 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.
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.
