As winter settles over the Tennessee River, the sky above Wheeler National Wildlife Refuge transforms as thousands of sandhill cranes descend on the wetlands and valley. These elegant, slate-grey birds with their distinctive crimson caps alter the refuge into a bustling sanctuary of social bugling and synchronized dances.
Witnessing the sheer scale of this migration is a reminder of the vital importance these protected waters play. While cranes start arriving in late autumn, the peak numbers gather between December and February. We visited in mid-January 2026 – refuge workers told us they had counted over 23,000 sandhill cranes, 38,000 ducks, 2,000 geese, and 23 whooping cranes for the season.
The refuge is a mosaic of bottomland hardwoods, pine uplands, agricultural fields, and tupelo swamps, tied together by river channels and tributary creeks. Local farmers cultivate crops in the fields and leave a portion behind after the harvest, creating a vital, reliable food source for wintering wildlife. For visitors, these open fields provide some of the best opportunities to see large concentrations of birds refueling in plain sight.
Several sites in Wheeler National Wildlife Refuge are designated Alabama Birding Trails. We explored three areas on the icy January morning.
Flint Creek Trail
We started at Flint Creek Day Use Area. In the field next to the parking area, we caught our first glimpse of dozens of sandhills cranes. Their loud bugles calling back and forth.
We hiked the Flint Creek Trail, an easy 1.28-mile double loop of boardwalks and dirt paths. It began over the water, giving us a view of the Flint Creek backwaters before heading into the forest. From the second loop, there were some great spots to stop and look out over the creek.
Beyond the sandhill cranes, we spotted a variety of locals like Carolina chickadees, Carolina wrens, killdeer, and tufted titmice. We even caught red-bellied woodpeckers, white-breasted nuthatches, and yellow-bellied sapsuckers busy at work in the trees.
Wildlife Observation Building and Atkeson Cypress Trail
Next, we moved to the visitor center. Here there are several birding options including the observation building, two photo blinds, and a hiking trail.
Wildlife Observation Building
The Wildlife Observation Trail is a short, 200-yard path from the visitor center to the two-story observation building. Both the trail and the first floor of the observation building are universally accessible.
If you’re visiting on a chilly winter day, the temperature-controlled observation building is easily the best viewpoint. We spent quite a while there, soaking up the landscape from different angles. It’s a great way to watch wildlife without having to brave the wind.
The water and surrounding fields were teeming with activity. We saw multiple waterfowl, including Canada geese, greater white-fronted geese, and snow geese, alongside green-winged teals, mallards, and northern pintails. We had great views of the sandhill cranes and even caught a northern harrier patrolling the area.
Between one beat and the next, there would be more cranes flying overhead, their shadows dancing on the water.
One of my favorite memories was watching sandhills walk, or try to land, on ice and slip – their wings quickly flapping to balance again.
Note: Since the refuge is a major hub for learning about migration, don’t be surprised if you run into a few school groups during your visit. Two different tours came through the building while we were there, and as you can imagine, a crowd of excited students can quickly change the vibe if you’re looking for a quiet moment with the birds.
Photo Blind
The main photo blind is a simple structure tucked at the edge of the swamp and field. There are 12 open-air windows set at different heights; opening the panels allows for a variety of angles and views of the landscape.
During my visit, a group of sandhill cranes fed in the field nearby. I stayed to watch them for as long as possible, even with the biting wind hitting me in the face the whole time.
Atkeson Cypress Trail
On the south side of the visitor center, the half-mile Atkeson Cypress Trail begins as a boardwalk through a cypress swamp and continues as a loop through the woods. The boardwalk and hard-packed crushed stone surface are universally accessible.
Atkeson also acts as a StoryWalk® trail in collaboration with the Decatur Public Library. During our visit, the book was Together: Animal Partnerships in the Wild by Isabel Otter.
Along the loop, a well-placed bench overlooks the agricultural fields – a perfect spot for visitors to relax and listen to the songbirds. In addition to squirrels, there was a flurry of movement and chirping in the trees. We found multiple species, from bold blue jays, northern cardinals, and northern mockingbirds to smaller visitors like Carolina chickadees, Carolina wrens, golden-crowned and ruby-crowned kinglets, white-throated sparrows, and winter wrens.
Visitor Center
While in the area, the visitor center serves as an essential jumping-off point, offering a deeper look into the ecology of the Tennessee River Valley. The interpretive exhibits provide context on the refuge’s diverse residents including the differences between sandhill and whooping cranes.
There is also a beautiful quote on the wall from E.O. Wilson, a biologist, naturalist, ecologist, and entomologist from Alabama.
Beaver Dam Boardwalk
Also called Beaverdam Swamp Boardwalk, this trail is on the eastern edge of the refuge. It takes visitors into Alabama’s largest tupelo swamp, recognized as a National Natural Landmark.
Water tupelo and bald cypress trees towered above the boardwalk, creating an atmosphere that felt like another world. The Beaverdam Creek Swamp was alive with sound, echoing with a mix of frog calls and bird songs.
Acoustics in the cypress swamp made it easy to track activity. The sharp drumming of pileated and red-bellied woodpeckers stood out, along with the distinct songs of Carolina wrens, winter wrens, and white-throated sparrows. Movement led to sightings of eastern bluebirds, hermit thrushes, and yellow-rumped warblers. Rounding out the morning were the familiar calls of tufted titmice, Carolina chickadees, white-breasted nuthatches, and golden-crowned kinglets.
The sight of thousands of sandhill cranes remains my strongest impression of Wheeler National Wildlife Refuge. Whether exploring the quiet corridors of Beaverdam Creek Swamp or watching these massive birds gather in open fields, the refuge offers an incredible front-row seat to these vital ecosystems.
