Dauphin Island, a barrier island off the coast of Alabama, is renowned among birdwatchers for its rich diversity of avian species. As one of the first landfalls for migratory birds crossing the Gulf of Mexico, the island serves as a critical habitat for over 360 bird species throughout the year. Whether you’re visiting during the spring migration, fall migration, or winter, this guide will take you through the island’s top birding spots with detailed information on what you can expect at each location, seasonal highlights, and practical tips to enhance your birdwatching experience.
1. The Causeway
Location and Access:
The Causeway, a scenic drive that connects Dauphin Island to the mainland, is easily accessible and offers numerous pull-off areas where birders can stop and observe. This area spans the stretch of road leading to the island, bordered by marshlands and shallow bays, making it a prime spot for waterfowl and shorebirds.
Birding Highlights by Season:
-
- Spring: During spring migration, expect to see large flocks of shorebirds like the American Avocet and Black-necked Stilt. This time of year is also excellent for spotting herons and egrets as they wade through the marshes.
- Summer: The warmer months bring nesting birds such as the Least Tern and Black Skimmer. The waterfowl population decreases, but there are still plenty of resident species to observe.
- Fall: Shorebird migration picks up again in the fall, with species like the Red Knot and Western Sandpiper making appearances. Watch for large mixed flocks along the mudflats during low tide.
- Winter: The Causeway remains active with wintering waterfowl such as Northern Pintail, Gadwall, and various species of ducks. Raptors like the Osprey and Northern Harrier are also frequently seen hunting in the area.
Practical Tips:
-
- Best Time to Visit: Early mornings are ideal for birdwatching along the Causeway, especially during migration seasons when bird activity is highest.
- Weather Considerations: While summer can be hot and humid, fall and winter mornings can be chilly with brisk winds off the water. Dress in layers and bring a windbreaker.
- Equipment: A spotting scope is recommended for viewing distant birds on the water, but binoculars are sufficient for closer observations.
2. Shell Mound Park
Location and Access:
Located on the northeast side of the island, Shell Mound Park is steeped in history, featuring ancient shell mounds that date back over a thousand years. The park is accessible via Lemoyne Drive, with parking available near the entrance. The dense canopy of live oaks and hackberry trees makes this site a favorite among birders, especially during migration.
Birding Highlights by Season:
-
- Spring: This park is a hotspot during spring migration, attracting neotropical migrants like the Hooded Warbler, Scarlet Tanager, and Blue Grosbeak. The trees offer abundant food and shelter, making it a prime location for “fallouts” where large numbers of birds rest after their long journey.
- Summer: While migration slows, resident species such as the Northern Cardinal, Carolina Wren, and Great Crested Flycatcher are still active. The shaded paths provide a cooler environment for summer birding.
- Fall: As birds head south for the winter, Shell Mound Park sees another wave of migrants, including Swainson’s Thrush, Red-eyed Vireo, and a variety of warblers. The foliage makes it challenging to spot some species, but patience is rewarded with diverse sightings.
- Winter: Winter is quieter, but species like the Hermit Thrush, Yellow-bellied Sapsucker, and Ruby-crowned Kinglet are common. The park’s sheltered environment also attracts lingering migrants that missed their earlier departure.
Practical Tips:
-
- Best Time to Visit: Mid-morning to early afternoon is optimal, as the sunlight filters through the canopy, illuminating the birds.
- Weather Considerations: The park is well-shaded, offering relief from the summer heat, but it can be damp and chilly in the winter. Waterproof shoes are recommended if the ground is wet.
- Equipment: A camera with a zoom lens is beneficial here, as birds often perch high in the trees. A birding app or field guide will help with quick identification.
3. Goat Tree Preserve
Location and Access:
Goat Tree Preserve is a smaller, more intimate birding spot located off of Audubon Street. The preserve is named after the legend of goats that once climbed the live oaks to escape rising floodwaters. Today, these trees serve as vital stopover points for migratory birds.
Birding Highlights by Season:
-
- Spring: The preserve comes alive with the sounds of warblers, including the Prothonotary Warbler, Blackburnian Warbler, and Northern Parula. These species use the dense canopy as a rest stop during their migration.
- Summer: Resident birds such as the Eastern Wood-Pewee and Red-eyed Vireo dominate the area. The thick underbrush also shelters ground-nesting species like the Eastern Towhee.
- Fall: The fall migration brings back many of the spring species, along with additional surprises like the Painted Bunting and Rose-breasted Grosbeak.
- Winter: Winter months are quieter, but species like the Yellow-rumped Warbler and Eastern Phoebe are still present, taking advantage of the preserve’s sheltered environment.
Practical Tips:
-
- Best Time to Visit: Early mornings are best when the birds are most active, especially during spring and fall migrations.
- Weather Considerations: The preserve is more exposed to wind, so it can feel colder than other areas on the island, especially in the winter. A hat and gloves may be necessary on particularly chilly mornings.
- Equipment: Binoculars are essential for spotting birds in the high canopy. Consider bringing a small portable stool if you plan to sit and watch for extended periods.
4. Audubon Bird Sanctuary
Location and Access:
The Audubon Bird Sanctuary, located at the eastern end of the island, is the largest protected area on Dauphin Island. This 137-acre sanctuary features a variety of habitats, including a freshwater lake, maritime forest, marshes, and dunes, making it a prime destination for birdwatchers. The sanctuary is accessible from Bienville Boulevard, with ample parking and well-maintained trails.
Birding Highlights by Season:
-
- Spring: During spring migration, the sanctuary is teeming with life. Look for species like the Indigo Bunting, Orchard Oriole, and the elusive Swainson’s Warbler along the forest trails. The lake and marsh areas attract waders such as the Snowy Egret and Glossy Ibis.
- Summer: The sanctuary remains active with resident species, including the Great Blue Heron, Osprey, and Clapper Rail. The lake often hosts Black-bellied Whistling-Ducks and the occasional Wood Stork.
- Fall: Fall migration mirrors spring, with additional species like the Yellow Warbler, Black-throated Green Warbler, and various sparrows passing through. The sanctuary’s diverse habitats offer different birding experiences depending on where you focus your attention.
- Winter: Winter brings a mix of waterfowl, raptors, and songbirds. The lake area is ideal for observing Bufflehead, Red-breasted Merganser, and Ruddy Duck. Keep an eye out for Bald Eagles and Northern Harriers soaring overhead.
Practical Tips:
-
- Best Time to Visit: Early morning is recommended for both the variety of species and the chance to see birds feeding before the heat of the day.
- Weather Considerations: The sanctuary’s maritime forest provides some shelter from wind, but the open areas near the dunes and lake can be chilly and windy in the winter months. Bring layers and a windproof jacket.
- Equipment: A field guide specific to Alabama or the Gulf Coast region can be helpful for identifying the diverse species seen here. A camera with a good zoom will allow you to capture the many photographic opportunities the sanctuary offers.
5. Pelican Peninsula and West End

You may spot species like the Sanderling, Red Knot, and even the occasional Jaeger skimming over the waves. The shorelines are often teeming with activity, particularly during high tides when birds are pushed closer to the beach.
- Winter: Winter months bring a different set of visitors to the coast. Look for species such as the Dunlin, Ruddy Turnstone, and various gulls including the Laughing Gull and Ring-billed Gull. The colder weather often brings brisk winds, so be prepared for a more rugged birding experience.
Practical Tips:
-
- Best Time to Visit: Late afternoon is an excellent time to visit, as the setting sun can provide beautiful light for photography and the birds are often more active as they prepare to roost for the night.
- Weather Considerations: While summer can be hot, the breeze off the Gulf usually provides some relief. However, in winter, the winds can be quite strong and chilly, so dress warmly and consider bringing a windproof jacket.
- Equipment: A good pair of binoculars is essential, and a camera with a telephoto lens is highly recommended to capture the action from a distance. A field guide or birding app can help identify the many seabird species you may encounter.
6. Airport Marsh and Cedar Point
Location and Access:
Airport Marsh and Cedar Point are located on the eastern side of Dauphin Island, near the airport. These wetland areas are less frequented by tourists, making them ideal for birders looking for a quieter experience.
