Migrating waterfowl and shorebirds.

From I-380, turn west on F-28 until you get to Greencastle Ave. Go north on Greencastle and turn west at the first 4-way intersection. This intersection is near the Gun Club Ponds. Go west and Round Pond will be on the north side just past the power lines.

This area has a large concentration of waterfowl and pelicans during migration. When water levels are right, large concentrations of shorebirds are found here during migration. The woodlands in the area produce significant numbers of migrating songbirds. Bald Eagle and Double-crested Cormorants nest in the area. There are large numbers of raptors in the area, some during migration and following the shorebirds, some nesting, and some wintering, such as Long and Short-eared Owls, Northern Harrier, and Rough-legged Hawk. There are heron rookeries, and large numbers of wading birds use the area during post breeding dispersal. The number of rare birds that have been found here over the years is quite large.
