"Kennesaw Mountain offers the best inland migration birding for warblers, vireos, and other landbirds in Georgia, if not the Southeast. Warbler counts of more than 20 species in a morning are not uncommon during peak migration, and this is one of the best spots in the East to see a migrant Cerulean Warbler. Hawk migration is scattered, but over a season ten or more raptor species can be seen, including all the falcons. It is very easy to bird here: Just walk up a paved road for 1.5 miles to the summit, and you may find birds anywhere along the road; the road gets a little steep in places.
The mountain is also heavily birded, which means that there is a good database being built of migration records and that there are usually other birders here during migration. The park also has several other lower-elevation trails with interesting breeding species. Key birds: Mountain: Raptor and landbird migrants. Forest Trails: Hooded and Kentucky Warblers, Wood Thrush, Summer Tanager. Marsh: Red-headed Woodpecker, Sedge Wren, Brown Creeper, Lincoln’s Sparrow."
