Alabama has the shortest coastline on the Gulf of Mexico, and that turns out to be the reason its wildlife is worth a trip rather than a footnote. A short coast that points south into open water behaves like a funnel. Everything crossing the Gulf has to arrive somewhere, and a great deal of it arrives here.
The clearest version of this happens every April. Songbirds wintering in Central America and the Caribbean launch north across six hundred miles of open water in a single flight, and the first land they meet is the Fort Morgan peninsula — a narrow finger of scrub oak and pine with Mobile Bay on one side and the Gulf on the other. In good weather they carry straight on inland and you barely notice them. When a north wind or a line of rain meets them halfway across, they arrive exhausted and drop into the first cover they can find, and Fort Morgan fills with warblers, tanagers, buntings and orioles in numbers that stop conversations. Birders call it a fallout. It is not scheduled, it cannot be booked, and for people who care about such things it is the single best natural event on this coast.
The second reason is negative space. Thirty-two miles of Alabama Gulf front is mostly condominium towers, and the exception is Bon Secour National Wildlife Refuge: roughly seven thousand acres protecting what is left of the state's undeveloped coastal dune system, set aside by Congress in 1980 precisely because there was so little of it. Behind the dunes there is scrub, maritime forest, freshwater at Gator Lake and salt marsh on the Bon Secour Bay side. It is the most complete surviving cross-section of what this coast looked like before the road.
Inside that dune system lives an animal found nowhere else on Earth. The Alabama beach mouse is federally endangered, nocturnal, pale enough to disappear against the sand, and entirely dependent on sea oats and the seeds they drop. Bon Secour holds one of the densest populations that remains. You will almost certainly never see one. The reason to know about it is that it explains every rope, every sign and every request to stay off the dunes between here and Fort Morgan.
Then there is the state park, which does the everyday work. Gulf State Park counts more than 370 species of birds, mammals, reptiles and amphibians across its ecosystems, and its paved trail network puts almost all of them within reach of a bicycle. Alligators along the Lake Shelby shore, ospreys overhead, gopher tortoise burrows in the sandy verges, armadillos in the leaf litter, and — with early starts and some luck — bobcats and coyotes on the dune-scrub segments.
What this coast does not have is a guided nature industry to match any of it. There are dolphin cruises out of Orange Beach and very little else. The good news is that almost everything on this page is free, self-guided and within twenty minutes of the beach.
