About Gulls
Here’s a fact that will either delight you or ruin your next beach vacation: there is no such thing as a seagull. Not scientifically, not taxonomically, not in any field guide published by anyone who knows what they’re talking about. "Seagull" is a folk name — a catch-all term that people use the way they use "bug" for any arthropod or "deer" for any large brown animal standing in a field at dusk. The birds people call seagulls are gulls, and gulls are a diverse family of waterbirds that show up in places far removed from any sea. Including, regularly and in significant numbers, North Louisiana.
If you’ve ever stood in a Walmart parking lot in Monroe after a rainstorm and watched a flock of white-and-gray birds wheeling overhead, screaming at each other like they’re arguing about whose turn it is to dive-bomb the abandoned french fries, you’ve seen gulls. Not seagulls. Gulls. And if you’ve ever driven across a bridge over the Ouachita River and spotted a sleek, fork-tailed bird hovering over the water before plunging headfirst after a fish, you’ve seen a tern. Both groups show up in North Louisiana, both groups are chronically misidentified, and both groups deserve more attention than the average "oh look, seagulls" dismissal they usually get.
Gulls vs. Terns: The Basics
Gulls and terns are both members of the order Charadriiformes, which they share with shorebirds, skimmers, and auks. They’re related, they overlap in habitat, and they’re both associated with water — but they’re built for very different lifestyles, and learning to separate them at a glance is one of the more useful birding skills you can develop in North Louisiana.
Gulls are the generalists. They’re stocky, broad-winged, and built for versatility — soaring, walking, swimming, and scavenging with equal competence. Their bills are heavy and slightly hooked at the tip, designed for tearing, grabbing, and generally eating whatever presents itself. Gulls are opportunistic feeders in the truest sense. They eat fish, invertebrates, garbage, other birds’ eggs, road-killed animals, fast food remnants, and anything else that holds still long enough. They’re the raccoons of the bird world — intelligent, adaptable, and completely unbothered by human proximity.
Terns are the specialists. They’re slimmer, more angular, and built for precision — long pointed wings, forked tails, and sharp, straight bills designed for plunge-diving after small fish. Where a gull will stand on a parking lot eating a discarded hamburger bun, a tern hovers over open water, spots a minnow from 30 feet up, and drops like a feathered missile to snatch it from below the surface. Terns are elegant in a way that gulls simply aren’t. They’re also significantly less interested in your french fries.
The quick field separation works like this: if the bird is stocky, walking around on the ground, and eating garbage, it’s probably a gull. If the bird is sleek, hovering over water, and diving headfirst after fish, it’s probably a tern. If the bird is standing on a parking lot light pole screaming at nothing, it could be either one, but odds favor gull.
Why North Louisiana?
People who associate gulls and terns exclusively with coastal beaches are missing a huge part of these birds’ ecology. Gulls are among the most widespread and adaptable bird families on the planet, and many species use inland waterways, agricultural fields, and urban areas as readily as they use coastline. North Louisiana’s major rivers — the Ouachita, Red, Mississippi (along our eastern border), and their tributaries — provide travel corridors that funnel gulls and terns into the region during migration and winter.
The large reservoirs and lakes in our coverage area also draw them. Lake Bistineau, Lake Claiborne, Poverty Point Reservoir, Toledo Bend (northern end), and the various oxbow lakes along the river corridors all provide the open water, fish populations, and loafing areas that gulls and terns need. During winter, ring-billed gulls are genuinely common across North Louisiana — common enough that most people stop noticing them, which is a shame, because a mixed gull flock on a winter lake is an identification challenge worth engaging with.
Agricultural land plays a role too. Freshly plowed or flooded fields attract gulls in numbers that would surprise anyone who thinks of them as strictly water birds. Gulls follow tractors the way cowbirds follow cattle — picking off invertebrates, worms, and insect larvae exposed by the plow. A flooded soybean field in Morehouse Parish in January might have 200 ring-billed gulls working the mud alongside the ibises and killdeer. They’re not lost. They know exactly where they are and exactly what they’re doing.
Seasonal Patterns
The gull and tern calendar in North Louisiana follows a clear seasonal rhythm, and understanding it will save you a lot of confusion about why you’re seeing (or not seeing) certain species at certain times. Winter is gull season. Ring-billed gulls arrive in October and November and remain through March, sometimes into April. They’re the default gull — the one you’ll see in parking lots, on lakes, over rivers, and in agricultural fields. Herring gulls are less common but regular, particularly around larger water bodies. Bonaparte’s gulls pass through during migration (November and March-April) and occasionally linger through winter in smaller numbers.
Summer is tern season, at least for Forster’s terns, which breed in the region and are present from spring through fall. Summer is also the quietest period for gulls — most have headed north to breed, and the parking lots and lakes are temporarily gull-free. Enjoy it while it lasts.
Migration periods (October-November and March-April) are the most interesting times, because that’s when species diversity peaks and unusual visitors are most likely. A diligent birder scanning a gull flock on Lake Bistineau in November might pick out Bonaparte’s gulls, ring-billed gulls, and the occasional herring gull all in the same scope view. Rarities — laughing gulls, Franklin’s gulls, lesser black-backed gulls — show up occasionally during migration and keep the dedicated gull-watchers on their toes.
The Species in North Louisiana
North Louisiana’s regular gull and tern cast is small but reliable. We cover four species in this section, each with its own article diving into identification, behavior, habitat, and where to find them across our 26 parishes.
Ring-billed gulls are the bread and butter — the most common and widespread gull in the region, present in large numbers from fall through spring. If you see a gull in North Louisiana between October and March, start with ring-billed and work from there. Bonaparte’s gulls are the small, elegant migrants that pass through in impressive numbers during November and again in March-April, often found on larger lakes and reservoirs. Herring gulls are the big ones — less common than ring-billeds but regular on larger water bodies during winter, and the species most likely to make you reconsider your assumptions about how large a gull can be. Forster’s terns round out the section as the resident tern — a fish-hunting specialist found along rivers, lakes, and marshes primarily during the warmer months.
Together, these four species give North Louisiana a year-round gull-and-tern presence that most people don’t realize exists. The next time someone tells you that gulls are coastal birds, invite them to stand in a Walmart parking lot in Monroe in January and count.
Accessibility
Gull and tern watching might be the most accessible birding in North Louisiana. Gulls live on parking lots, boat ramps, and lake beaches — the paved, flat, drive-up-and-watch habitats that require exactly zero trail access. You can identify ring-billed gulls from a fast-food drive-through without unbuckling your seatbelt.
The sounds are half the experience. A winter gull flock on a parking lot generates a constant, argumentative soundtrack — high-pitched laughing calls, squabbling squeals, and the heavy thwap of wings when two birds dispute a french fry. Forster’s terns hunting over a lake produce a harsh "kyarr" that cuts through wind noise like a siren. Herring gulls have a deep, wailing cry that carries across open water and sounds like the ocean showed up in Ouachita Parish. Roll down the windows at any lake boat ramp in January, and the gulls will introduce themselves by voice before you’ve parked.
