Fall Bird Migration in Louisiana

Louisiana is where the Mississippi Flyway runs out of continent: the coastal refuges of Cameron Parish take in wintering white-fronted and snow geese, and the state agency flies its waterfowl surveys from September through January.

Public viewing sites in Louisiana

Every place below is one an agency itself describes for watching the fall passage, with the agency named and linked, the species it documents there, the months it names as the peak, and the facility that exists: a tour route, a platform, a tower, a visitor centre. Where the agency wrote a sentence worth reading, it is quoted exactly.

Established in 1937 to provide wintering habitat for waterfowl, the refuge says large wintering concentrations of white-fronted and snow geese can be found here, with smaller numbers of Ross's and Canada geese and a heavy showing of puddle ducks, and that Lacassine Pool serves as a sanctuary where a large concentration of birds feeds and rests. It names fall and winter as the best times for waterfowl observation and photography and points visitors to the three mile auto tour with interpretive signs at the Pool, asking them to stay in their vehicles to limit disturbance. Refuge office at 209 Nature Road, Lake Arthur.

“Large wintering concentrations of white-fronted and snow geese can be found here, along with predominately puddle ducks, such as pintails, blue and green-winged teals, mallards, gadwalls, shovelers, and American widgeons.”
US Fish and Wildlife Service, Lacassine National Wildlife Refuge, quoted exactly.

Created in 1988 to preserve and protect wintering waterfowl, the refuge describes itself as a winter home to thousands of ducks and geese and names white-fronted and snow geese among them. It says the visitor center, exhibits and auto tour route are the primary attractions for the visiting public; the visitor center at 1428 Highway 27, Bell City, opens Tuesday to Thursday, and the refuge sits on the Creole Nature Trail All-American Road about 25 miles southeast of Lake Charles. The agency states no peak months beyond winter.

“The refuge provides a winter home to thousands of ducks and geese including green-winged teal, mallards, northern pintail, ring-necked ducks, white-fronted and snow geese.”
US Fish and Wildlife Service, Cameron Prairie National Wildlife Refuge, quoted exactly.

The coloured grid is where people have uploaded a verified sandhill crane record to iNaturalist in September, October, November and December, brighter where more have been logged. It is a map of reports rather than of birds: it thickens around refuges, car parks and towns because that is where observers stand, and it shows past reports rather than birds present today. Pins are public viewing sites an agency itself describes; grey dots are US Fish and Wildlife Service refuges and hatcheries, drawn because the refuge system is where most of the staging happens.

When

When the passage peaks in Louisiana

Louisiana Department of Wildlife and Fisheries, White Lake Wetlands Conservation Area birding trail puts the Louisiana peak at November through February. That describes a pattern across past autumns. The week itself swings with the weather: a cold front to the north moves cranes and geese south in a single night, and a warm spell holds them for weeks. Dawn and the last hour before dusk are when cranes and geese move between the fields and the water, and that movement is the spectacle the platforms are built for.

Louisiana is where the Mississippi Flyway ends, and the agencies describe fall as the season the coast fills rather than a passage overhead. The Service's Cameron Parish refuges were each established for wintering waterfowl: Lacassine documents large wintering concentrations of white-fronted and snow geese around Lacassine Pool, Cameron Prairie calls itself a winter home to thousands of ducks and geese including both species, and Sabine's Wetland Walkway tower is the best known viewing structure on the Creole Nature Trail. The state agency publishes what it counts rather than where to look: LDWF flies transect surveys of coastal Louisiana from September through January, cruise surveys of Catahoula Lake and the northeast, and takes part in the Mississippi Flyway goose count in early January. Its one designated public birding trail with a stated fall window is at White Lake, where staff say waterfowl show from November through February.

Below, one curve per species the agencies document in Louisiana: every research grade observation members of the public have uploaded to iNaturalist for the state, by calendar month across every year the platform holds, with September to December shaded. Counts of uploads, so they measure observers as well as birds, and the shape is worth reading where the absolute numbers are not.

Snow goose

297 research grade snow geese observations have been uploaded to iNaturalist for Louisiana across every year the platform holds, and 47 percent of them fall in the four shaded autumn months. The busiest month in the record is January. An autumn month carries about 1.81 times as many uploads as an average month outside autumn. People upload most of everything in April, so a bar that rises after that is the stronger signal. Counts of what people reported, measuring observers as well as birds. See the autumn records.

Ross's goose

56 research grade Ross's geese observations have been uploaded to iNaturalist for Louisiana across every year the platform holds, and 41 percent of them fall in the four shaded autumn months. With fewer than 60 records the series is too thin to summarise, so the bars stand on their own. Counts of what people reported, measuring observers as well as birds. See the autumn records.

Greater white-fronted goose

181 research grade greater white-fronted geese observations have been uploaded to iNaturalist for Louisiana across every year the platform holds, and 56 percent of them fall in the four shaded autumn months. The busiest month in the record is January. An autumn month carries about 2.53 times as many uploads as an average month outside autumn. People upload most of everything in April, so a bar that rises after that is the stronger signal. Counts of what people reported, measuring observers as well as birds. See the autumn records.

The movement is watched from the designated pullout or platform: the birds settle on shallow water for the night, and the roost itself is the one place a viewing site is never placed. “Sandhill cranes flying over Sherburne National Wildlife Refuge (24542820818)” by USFWS Midwest Region from United States, CC BY 2.0
Latest reports

What people have reported in Louisiana lately

The most recent research grade autumn observation of each species that anyone has uploaded to iNaturalist for Louisiana, as a date and the platform’s own coarse locality. Evidence that people do find snow goose and ross's goose here. Each is one bird on one past day: the flocks move with the weather, so where they are this week is what the agency page and its counts answer.
