The Ice Age Trail crosses here. The south trail leads into a lowland habitat where Alder Flycatcher and Chestnut-sided Warbler are found. On the trail north is a Red Pine plantation where Red-breasted Nuthatch, Pine Warbler, and Cooper’s Hawk are found.
Past the plantation and the ridge of an esker that provides nice views of the surrounding forest habitat, the trail descends to a stream and a footbridge where Louisiana Waterthrush might be found. Crossing the bridge you enter a mature climax forest. Here Red-shouldered Hawk, Cerulean Warbler, and Yellow-throated Vireo are possible.
Past the contact station take the first left to the boat landing. At this intersection, there is a small stand of Red Pines where Red-breasted Nuthatch and Pine Warbler can be found. From here to the small stream crossing, the south side of the road often has American Woodcock (early spring), Veery, Winter Wren (uncommon early spring/rare summer), Brown Creeper, Mourning Warbler, and Northern Waterthrush. Red-shouldered and Broad-winged Hawk are often seen or heard. From the stream crossing to the boat landing look for Eastern Wood-Pewee, Wood Thrush, Blue-gray Gnatcatcher, Cerulean Warbler, and Scarlet Tanager. In the vicinity of the boat landing look for Virginia Rail, Osprey, Bald Eagle, both Willow and Alder Flycatchers, Marsh Wren, and Swamp Sparrow.
In late March-April a good variety of migrating waterbirds can be found from the boat landing including Common Loon. The picnic area is often the best spot to find Yellow-throated Vireo, Pine, and Cerulean Warbler. The bottomlands across the road from the picnic pavilion may have Black-and-white and Mourning Warbler.
Along the road to the trash recycling area Broad-winged Hawk, both cuckoos, Black-throated Green Warbler, and Hooded Warbler are possible.
Other birds that can be found at any time on the property are Barred Owl and Pileated Woodpecker.
