The boulder fields of Horse Pens 40 are a fascinating place to visit, at any time of year. The best times for birding are surely during spring and fall migration, when the elevation of the site turns the mountain into a notable migrant trap. The ridges are productive for hawk migration from September through November. Do not neglect to bird the farm and field habitat along US 231 and Ct. Clair County 35 while in the area.
Logan Martin Dam is notable for being one of the premier locations in the state for viewing wading birds, particularly Black-crowned Night Herons. Waders in large numbers are attracted to the rough water just below the dam, where an abundance of fish are always available near the rocky shoreline. It is also reliable for year-round sightings of Bald Eagles.
Neely Henry Dam on the Coosa River offers great opportunities to observe a variety of water-loving birds. Winter brings gulls (mostly Ring-billed, some Bonaparte’s and Herring, rarely Glaucous, Lesser Black-backed, etc.) and a few Forster’s Terns, primarily over the deep waters above the dam. Colonies of Barn Swallows and Cliff Swallows build their mud nests on the dam structure, and activity is intense from late March to September. This is also a peak time to observe large numbers of wading birds.
Ten Islands Historical Park, on the shores of Neely Henry Lake just above the dam, offers first-rate birding. Though the park itself is small, there is a vast amount of excellent habitat here – the entrance road provides shoreline access to deep water, pullout areas to check grassy edges and early second-growth pines. There is a good wooded trail from the parking lot along a finger of the lake. The park is good for songbirds, swallows, waterfowl, raptors, and more.
