Cameron Parish.
Due to its large size and location, it has a wide variety of habitat types, including prairie, gallery woods, hardwood swamps, freshwater and saltwater marshes, cheniers (oak woods on old ridges of the gulf beach), beach, and open gulf. It is also very sparsely populated. For songbirds and migration, coastal locations such as the Holleyman-Sheely Migratory Bird Sanctuary and the Jetty Woods (private property) are optimal. For freshwater marsh birds, the Sabine NWR boardwalk, the Cameron Prairie NWR, and the Gibbstown Bridge are accessible, birder-friendly stops. For viewing beaches and mudflats, Highway 82 near Holly Beach, the East Jetties at Cameron, and Broussard and Rutherford Beaches are outstanding birding areas.
Grand Isle.
One of the top birding sites on the Gulf coast, this barrier island at the mouth of Barataria Bay may have more birds per capita than anywhere else in the US during a spring migration fallout, with warblers in abundance. Sureway Woods has a seventeen acre remnant of the maritime live oak forest that once blanketed the islands that protect Barataria Bay. Grand Isle's cheniere forest is unique, the only place in the world where this habitat still grows on a barrier island. Besides during the height of migration, you should be able to find shorebirds, ducks, gulls, terns, wading birds and many songbirds in the spring and fall.
Sabine National Wildlife Refuge.
Located on LA-27, this is a recommended birding stop. The walkway here has an observation tower, offering panoramic views of miles of the level marsh terrain. During April and May, visitors are sure to see migrating warblers as well as other migrants that stay to nest including barn and tree swallows, kingbirds, kingfishers, orchard orioles, and yellow-billed cuckoos. White-fronted and white ibis nest on the refuge as do purple gallinules, roseate spoonbills, great egrets, and great blue herons. Large numbers of migrating shorebirds also visit the refuge in spring and fall. In winter, thousands of ducks including Blue-winged Teal, American Widgeon, Gadwall and as many as 50,000 Common Moorhens congregate here. White Pelicans over-winter as do some 10,000 or more Snow Geese.
The Peveto Woods Bird and Butterfly Sanctuary
A part of the Creole Nature Trail, Peveto Woods Bird and Butterfly Sanctuary is located on two major bird migration routes: the Central and Mississippi Flyways. Species of migratory waterfowl, such as ducks and geese, are the most common, along with water birds such as the laughing gull, royal tern, black skimmer and Louisiana's state bird - the brown pelican. The most common birds found in the marshes include marsh wren, seaside sparrow, redwinged blackbird and sandpipers, etc. At one time, a single refuge pool can host more than 800,000 ducks and geese. At its peak during spring and fall migration, sightings of 250 species of birds have been recorded here. The Sanctuary is located 8 miles west of Holly Beach.
