What Pelicans Eat in Louisiana: A Field Guide to Their Diet
Pelicans in Louisiana mainly eat fish, with menhaden and mullet topping the menu. They scoop up prey in coastal marshes and nearshore waters. If you want to see them feed, head to the Gulf Coast or Lake Pontchartrain at dawn or dusk.

1. What is the main food source for pelicans in Louisiana?
Louisiana's brown and American white pelicans rely heavily on small, schooling fish. The most common are menhaden (also called pogy), mullet, and anchovies. They also eat shrimp, crabs, and occasionally small birds like ducklings, but fish makes up over 90% of their diet. Menhaden are especially important because they're abundant in the state's estuaries.

2. How do pelicans hunt for food in Louisiana waters?
Brown pelicans dive from as high as 60 feet, plunging headfirst to catch fish below the surface. American white pelicans use a method called cooperative feeding: they line up in the water and herd fish into shallow areas before scooping them up in their pouch. In Louisiana, you'll often see white pelicans working together in groups, particularly in wetlands nearGrand Isle.
3. Where are the best places to see pelicans feeding in Louisiana?
Coastal marshes and barrier islands are prime spots.Grand Isle State Parkand theSt. Bernard Parish wetlandsoffer reliable sightings. Lake Pontchartrain's Causeway area also draws pelicans chasing mullet. Near passes likeSouth Pass, you'll see them working the tidal rips. For the best experience, visit during low tide when fish are concentrated.

4. When do pelicans feed and how does their diet change seasonally?
Pelicans feed most actively in early morning and late afternoon. In spring and summer, brown pelicans eat more menhaden because the fish spawn nearshore. White pelicans, present mainly in winter, switch to mullet and shrimp as those become available. During breeding season, adults prioritize high-energy fish like anchovies. If you're watching in fall, expect them to target mullet runs along the coast.

5. What field sign should you look for to identify pelican feeding behavior?
A practical field note: when you see a brown pelican hover and then drop like a stone, it's hunting. Watch for a splash and a pouch full of water. White pelicans give away their location by the V-shaped formation they form when herding fish. Also check for gulls circling overhead: they often steal prey from pelicans, so a gull mob means a feeding event is happening below.
6. How does pelican diet connect to their role in Louisiana's ecosystem?
Pelicans are indicator species for fish stocks. When menhaden are plentiful, pelican numbers stay healthy. In the 20th century, DDT caused eggshell thinning and nearly wiped out Louisiana's brown pelicans. Since their recovery, they've become a symbol of coastal health. Their diet reflects the productivity of local waters, so tracking what they eat helps biologists monitor the estuary.
