The Southeastern US is a hotspot for birders. To promote avian tourism, the Georgia Department of Natural Resources has developed the Colonial Coast Birding Trail (http://georgiawildlife.com/ColonialCoastBirdingTrail), a list of sites where visitors can experience both Georgia history and wildlife. More than 300 species of birds have been spotted along the coast, including spring and fall migrants. As I indicated in an appendix in the book: 'Where to Go to Enjoy Georgia Coastal Wildlife', the birding trail locations are also great for observing the many other denizens of the salt marsh estuaries, as well as the plants that grow in the marshes and on the sea islands.
One of my favorite coastal birds is the beautiful painted bunting, which overwinters in Mexico and Central America and migrates in spring to breed either in a region west of Alabama, or in a smaller area along the Southeastern Atlantic Coast. Both painted and indigo buntings are often heard and seen on Georgia's sea islands during summer.
Former President Jimmy Carter, an avid birdwatcher, was thrilled to finally get a good look at a painted bunting near his hometown in Georgia in 2002, as explained in this 2012 Birdwatching magazine article: 'A Life Bird for a President.'
