This gem of a preserve protects lakeshore, old fields, wetlands, and a unique gorge, and the property abuts the Ulao Waterfowl Production Area, so the chances of good birds are high. Well-maintained trails, including wheelchair-accessible gravel sections, lead through the area.
The preserve’s namesake, Lion’s Den Gorge, is a coastal ravine sheltering a cedar and hardwood forest that supports a number of rare, mostly northern, relic plant species. Rainfall runoff and springs flowing from the ravine’s walls contribute to an intermittent stream running into Lake Michigan.
I can bird the 72-acre site in two or three hours. I have had incredible spring mornings, with abundant warblers, sparrows, puddle and diving ducks, raptors, and numerous other migrants. Prized species seen fairly regularly include Olive-sided and Yellow-bellied Flycatchers, Gray-cheeked Thrush, Black-throated Blue and Connecticut Warblers, and Rusty Blackbird. Large numbers of waterfowl, including mergansers, loons, Common Goldeneye, and scoters, make their way past the bluffs. On days with winds favorable for raptors, I have seen many falcons, accipiters, and buteos fly by at eye level or pop up over the bluff. — Joan Sommer
