My list from last week's Georgia trip, as I can best recall. The experts identified quite a few more than I could and went home with longer lists.
The mix of habitats is the key. The 7 mile-long island's habitats include ocean beach and dunes, salt marsh, a 30-acre fresh water marsh impoundment, Wax Myrtle scrub, and maritime forest.
A few comments for you bird people: There is no big warbler migration down there. I don't know why. It must be fly-over country for them. Also, there are no ducks now - they headed north a couple of months ago. There are no Bob White Quail and essentially no Wild Turkey. Seems perfect for them, but they are not there. Snakes are tough on ground-nesting birds.
That's not my photo. That's a Painted Bunting, quite common down there.
Birding is, I read, the fastest-growing hobby in the US. It gets people outdoors and moving and it can be as challenging as you desire. Expertise in anything knows no limit.
My list below the fold for those interested. An asterisk means a first for me.
