Poems About the Forster's Tern: Year-Round Gulf Coast Tern Poetry from Dulac, Louisiana
Forster's Tern poetry from the marsh channels and coastal bays of Dulac, Louisiana — by Mitchell Parfait, from Dulac, Louisiana, where Sterna forsteri — the Forster's Tern, the tern that never leaves — works the interior marsh channels all year long, including the cold months when every migratory bird has already gone.

Poetry from the water's edge. By someone who lived it.
The Forster's Tern is the one that stays. While the Common Tern, the Least Tern, and most of the other terns that work the Louisiana coast pull out in September and October heading for warmer latitudes, Sterna forsteri remains. It is present in the coastal marshes of Louisiana in December, in January, in February — the same bird working the same channels through the cold months when the tourists are long gone and the shrimp boats have mostly tied up and the marsh is quiet. If you see a tern over a Louisiana bayou in winter, it is almost certainly a Forster's. That is not a small fact. It is the kind of fact that means something to a man from Dulac who has built his whole life on the same ground.
The Forster's Tern & the Louisiana Bayou
Sterna forsteri — the Forster's Tern. Named for the naturalist Johann Reinhold Forster, who sailed with Captain Cook on his second voyage, but the bird itself is as close to home as any coastal species on the Louisiana Gulf. While the Common Tern arrives in spring and departs in fall, and the Least Tern follows a similar pattern, the Forster's Tern is a year-round Gulf Coast resident — breeding in the Louisiana coastal marshes in spring and summer, and remaining through winter when the migratory species have cleared out. In December over Bayou Dulac, over Timbalier Bay, over the shallow trawl channels south of town, if there is a tern working the water, it is Forster's. That permanence lives in DULAC POETRY.
In breeding plumage, the Forster's Tern is a striking bird: orange bill with a clean black tip, a deep black cap from forehead to nape, white body, pale gray back and wings, and deeply forked tail with long streamers that trail in flight. The silvery primaries — the outer flight feathers — catch the light in a way that distinguishes the bird from the Common Tern at range, especially in the low-angle morning light over marsh water. By winter, the full black cap gives way to a distinctive black mask through and behind the eye — not a full cap like summer, but a dark patch that makes the bird look masked, like it changed its appearance without changing its address. It is the same bird. It just looks different in the cold months. It stayed.
Mitchell Parfait grew up on Bayou Grand Caillou in Dulac, Terrebonne Parish — the same bayou system that drains south through the marsh toward Timbalier Bay and the outer coast. A man fishing those channels in December would know the Forster's Tern the way you know a neighbor who never leaves town — by sight, by behavior, by the fact of their continued presence when everyone else has gone. Order on Amazon and read the poems that came from that coast.
Biology & Field Identification
The Forster's Tern (Sterna forsteri) is a medium tern — 13 to 14 inches long with a wingspan of around 30 inches, nearly identical in size and structure to the Common Tern (Sterna hirundo). The two species can be genuinely difficult to separate in the field, and that difficulty is itself useful: because the Forster's stays through winter and the Common Tern does not, if you are looking at a tern over a Louisiana marsh in January, you already have your ID. The bill in breeding plumage is orange-red with a black tip — sharper and more distinctly orange than the Common Tern's slightly more red-orange bill. In winter the bill darkens, but the key winter field mark is the eye mask: where the Common Tern in winter shows a dark smudge on the nape and ear coverts, the Forster's in winter shows a distinctive black patch running through and behind the eye against a white head — the “eye mask” that gives the bird a different look from its summer self. Those field marks run through the poems.
The silvery primaries are a consistent year-round field mark: the outer flight feathers of the Forster's Tern are paler and more silvery than those of the Common Tern, catching light differently as the bird banks over the marsh. In the low, flat light of a Gulf Coast dawn, the Forster's primaries will catch the sun from above and flash white-silver against the gray sky — a bright mark that is visible at distance on a calm morning. The deeply forked tail, with long streamers in breeding plumage, is the classic tern silhouette: the bird's flight is buoyant and graceful, light on the air in a way that the heavier gulls never are.
The Forster's Tern hunts by hovering and plunge-diving for small fish in shallow water — but unlike the Common Tern, which favors open bay water and near-shore Gulf, the Forster's is more likely to work interior marsh channels, shallow tidal creeks, and bayou edges. It is a bird of the inside water, not the open coast — a marsh tern as much as a bay tern — and that preference makes it the tern most likely to be seen from a bayou boat or a levee road in any season. Its call is a harsh “kyarr” — rough, carrying, the sound of a bird that is comfortable making noise in empty country. The year-round range on the US Gulf Coast includes Louisiana's coastal marshes, Terrebonne and Lafourche parishes, the bays and barrier island channels from Timbalier Bay to the Isles Dernieres.
In the marsh, the Forster's Tern nests differently from the Least Tern and the Common Tern — both of which nest on bare sand and shell on the barrier island beaches. The Forster's builds a floating nest in the marsh vegetation itself: a platform of cordgrass, roseau cane, and debris that floats on the water surface in the marsh interior, often in the same areas where herons and egrets nest. It is a bird that commits to the marsh the way a marsh bird commits — nesting on what the marsh gives it, which is water and grass and the knowledge that what you build may float or may not.
Forster's Tern Country: Dulac & the Louisiana Coast
The Forster's Tern in Terrebonne Parish is everywhere the water is. Timbalier Bay to the south of Dulac. The marsh channels that drain out of Bayou Dulac and the surrounding wetlands. The trawl cuts and spoil bank edges where boats have worked the shallows for generations. The Isles Dernieres barrier chain at the outer edge of the parish, where the bay meets the Gulf. Unlike the Least Tern or the Common Tern, which concentrate on the outer barrier beaches for nesting and work the open bay water for food, the Forster's is comfortable all the way into the interior — up the channels, over the marsh flats, in the narrow cuts between the cordgrass where a boat barely has room to turn. It is the tern of the inside water. That landscape is what DULAC POETRY is written from.
If you fished the marsh channels south of Dulac in winter — set crab traps in December, ran trotlines in January, worked the flounder flats in February — the Forster's Tern was there. Not because you went looking for it. Because it was always there. It was the tern you grew up knowing the way you know a cousin or a neighbor: not by formal introduction but by constant presence, the fact that it was always in the same place you were. Every other tern you might see on those channels was a visitor. The Forster's was a resident. That is a different kind of relationship to a place.
The Forster's Tern relationship with the shrimp fleet is real and practical. The bird follows working boats — not out of sentiment but out of efficiency. Trawling disturbs the bottom and churns up baitfish and shrimp that flush toward the surface, and the Forster's Tern is fast enough and agile enough to work that disturbance the way a fisherman works a running tide: you put yourself where the conditions favor you, and you work what is moving. A shrimp boat dragging a channel is making food available to anything fast enough to take it, and the Forster's knows that.
The same land loss story that threatens the Least Tern's barrier island nesting beaches threatens the Forster's Tern's interior marsh nesting habitat. The marshes where it builds its floating nests are subsiding — converting from marsh to open water at a documented rate across coastal Louisiana. A floating nest on cordgrass requires the cordgrass to still be there. The same coast that has lost a foot of beach from the outer barrier islands has also lost acres of interior marsh per year for the past several decades. The Forster's Tern comes back to Dulac's marsh every spring and finds what is still there — and builds on it. That's Mitchell Parfait's coast too. Order DULAC POETRY.
Why Bayou Poets Write About the Forster's Tern
The tern that doesn't leave is the subject. Not the flashier birds, not the one with the cleanest dive or the loudest colony — the one that is still there in December when the tourists are gone and the migrants have cleared out and the marsh goes quiet in a way it only does in winter. The Forster's Tern working the same channel you are working, in the same cold, with no audience, for the same reasons it was there in July — that is a different kind of bird. Year-round presence is a statement about a place. It says: this is where I belong. Not this is where I came to find food. This is where I am from. Read the poems that came from that attention.
The winter eye mask is a detail worth staying with. In summer, the Forster's Tern has the full black cap of a breeding tern — the same cap the Common Tern and the Least Tern wear in the warm months. But in winter, when the migrants are gone and the Forster's is the only tern left, the cap recedes to a black mask through the eye. The bird changes its appearance for winter without changing its address. It becomes something slightly different to get through the cold season — quieter, more anonymous, the mask rather than the crown — and then in spring it comes back into full plumage and the colony begins again. That is a particular kind of transformation: the kind that happens in place, without departure. You stay, and winter changes you, and spring brings you back to what you were.
The floating nest is the other thing. The Forster's Tern builds a nest on what is moving, on what is unstable, on what is, in the case of coastal Louisiana, sinking. A platform of marsh grass floating on the surface of water that is slowly converting from marsh to open bay — the nest literally floating on the change. And the bird comes back to the same marsh channel and builds again, on whatever the marsh gives. There is no fixed point. There is only the work of building on what's still there and trusting it will hold long enough. Find that world in DULAC POETRY.
December, and I am running the channel south of Dulac with no particular reason to be running it except that it is mine, it has always been mine, and the marsh on either side is smaller than it was the December before.
The Forster's Tern is working the same water, twenty yards ahead of the bow, hunting the same way it hunts in June — hover, read, drop, come up with fish.
Everyone else is gone. The other terns cleared out in September. The tourists never made it past October. Half the shrimp boats tied up before Thanksgiving.
The tern doesn't know it stayed. It just didn't leave. That is the whole difference between us and the migrants — not that we are braver, not that we chose it.
We just never left, and after enough years that becomes the same thing as belonging.
I have been on this bayou my whole life. The tern is here every December. I don't know what else there is to say about a place except that you keep going back to it, and after a while it stops being a choice.

The Forster's Tern working a marsh channel south of Dulac in December — the only tern left, the silvery primaries catching the winter light, the black eye mask marking the season without marking a departure. The floating nest in the cordgrass, built on what is sinking, rebuilt the next spring when the bird comes back to the same spot and finds what is still there. The winter channel, the quiet marsh, the man in the boat who is also still there because he never left and after a while that stops being a fact and becomes an identity. DULAC POETRY is the record of that staying — the coastal marsh, the working water, the creatures and the people whose whole lives are organized around a place that the rest of the world keeps saying is disappearing. The tern comes back. Mitchell comes back. The poems are from that return. The book is available on Amazon in paperback and Kindle.
If you are looking for poems about the Forster's Tern — or for poetry about the Louisiana Gulf Coast, the interior marsh channels and winter bays where the year-round tern works the same water through every season, the man from Dulac who has watched that marsh and those birds his whole life — this is where that work lives. DULAC POETRY is available in paperback and Kindle on Amazon: amazon.com/dp/B0FXVZDLZG. Written from the same coast where Sterna forsteri stays through the winter, wearing its black eye mask in the cold, building its floating nest in the cordgrass in spring, the only tern left when the channel goes quiet — poetry from the water's edge.
