43 Bird Names That Start With S: A Birdwatcher’s Identification Guide
October 24, 2026
From the sparrow hopping across a parking lot to the prehistoric-looking Shoebill Stork wading through an African swamp, bird names that start with S cover more ground than almost any other letter in the alphabet. Sparrows, swans, swifts, and skuas all share that single starting letter, yet they belong to wildly different families, habitats, and diets.
This bird identification guide walks through 43 species and groups whose common names begin with S, organized the way a field guide would: by what the bird looks like, where it lives, and how to tell it apart from its lookalikes. Whether a backyard birdwatcher is trying to separate a House Sparrow from a native sparrow or a traveler wants to recognize a Seriema on a trip to Brazil, this ornithology reference breaks down the identifying details that matter most.
Pro Tip: Keep a notebook of size, bill shape, and leg color for every unfamiliar bird you spot. Those three traits narrow down most bird names that start with S faster than color alone.
1. Sparrow
The House Sparrow (Passer domesticus) is the sparrow most Americans see daily, nesting under eaves and foraging around parking lots in nearly every city on the continent. It was introduced from Europe in the 1850s and has since outcompeted some native cavity-nesters for nesting space.
Native sparrows, such as the Song Sparrow and White-crowned Sparrow, are usually streakier and more closely tied to brushy or grassy habitat than their bold, gray-capped European cousin. Bill shape is a reliable clue: sparrows carry a short, conical bill built for cracking seeds.
2. Stork
North America’s only native stork is the Wood Stork (Mycteria americana), a large wading bird with a bald, dark gray head and a heavy, slightly downturned bill. It breeds in the swamps and wetlands of the southeastern United States, particularly Florida, Georgia, and South Carolina.
Wood Storks feed by wading through shallow water with their bill partly open, snapping it shut the instant a fish or crustacean brushes against it. This tactile hunting method lets them feed effectively even in murky water where sight is nearly useless.
3. Sandpiper
The Spotted Sandpiper (Actitis macularius) is one of the most widespread shorebirds in North America, recognizable by its constant bobbing or teetering motion while walking along shorelines. In breeding plumage, bold dark spots cover its white underside.
Sandpipers as a group range from sparrow-sized peeps to larger curlews, and many species look nearly identical outside the breeding season. Leg color, bill length, and habitat preference (mudflat versus rocky shore) help separate the lookalikes.
4. Swallow
The Barn Swallow (Hirundo rustica) is the most familiar swallow across the United States, known for its deeply forked tail and steel-blue back. It builds cup-shaped mud nests on barn rafters, bridges, and porch eaves, often returning to the same site year after year.
Swallows hunt insects on the wing, cutting tight turns low over fields, ponds, and open water. Their long, pointed wings distinguish them in flight from the stockier, more fluttery flight style of swifts.
5. Seagull
“Seagull” is not an official scientific category but a common nickname for the roughly two dozen gull species found along North American coasts and inland waterways. The Herring Gull (Larus argentatus) is one of the most widespread, with gray wings, a white body, and a red spot near the tip of its yellow bill.
Several gull species, including the Laughing Gull, develop a fully black head during the breeding season before molting back to a white or pale gray head in winter. That seasonal switch trips up a lot of beginning birders comparing field guide photos against live birds.
6. Swan
The Trumpeter Swan (Cygnus buccinator) is the largest native waterfowl species in North America, with an all-black bill and a deep, trumpet-like call that gives the species its name. The introduced Mute Swan (Cygnus olor), by contrast, carries a bright orange bill with a black knob at the base.
Both species share the unmistakable, entirely white wings and body that make swans so easy to spot from a distance, even if the orange beak coloring is the faster way to tell Mute Swans apart from native species on a pond.
7. Scaup
The Greater Scaup (Aythya marila) is a diving duck that winters along both coasts and on large inland lakes, with males showing a glossy green-black head and pale gray back. Its close relative, the Lesser Scaup, looks almost identical and is best separated by head shape and the faint purplish sheen on its crown.
Scaup dive underwater to feed on mollusks and aquatic vegetation, often forming large rafts of hundreds of birds on open water during the winter months.
8. Shearwater
The Sooty Shearwater (Ardenna grisea) spends most of its life far offshore, gliding low over ocean waves on long, stiff wings in a flight style known as dynamic soaring. It is dark brown overall with pale underwing linings visible as the bird banks.
Shearwaters nest on remote islands in the Southern Hemisphere, then migrate enormous distances across the Pacific and Atlantic to feed, making them a highlight for pelagic birding trips off the California and East Coasts.
9. Spoonbill
The Roseate Spoonbill (Platalea ajaja) is one of the most colorful wading birds in the southeastern United States, with bright pink plumage and a flat, spoon-shaped bill it sweeps side to side through shallow water. That bill shape, unique among American wading birds, is what gives the whole family its name.
Young spoonbills are pale pink and gradually deepen in color over several years as they mature, with the brightest pink concentrated on the wings and shoulders of breeding adults.
10. Swamphen
The Purple Swamphen (Porphyrio porphyrio) is a chicken-sized marsh bird with deep purple-blue plumage, a bright red bill and frontal shield, and oversized red legs. Native to the Old World, it has established a growing population in South Florida wetlands after escaping captivity.
Swamphens walk on floating vegetation using long toes that spread their weight, letting them cross lily pads and reed mats that would sink a heavier wading bird. For anyone curious about other oddly named marsh and wetland birds, the birds that start with Q list includes several equally obscure species.
11. Snowcock
The Himalayan Snowcock (Tetraogallus himalayensis) is a large, partridge-like bird native to the mountains of Central Asia. A small population was introduced to the Ruby Mountains of Nevada in the 1960s and 1970s, and it remains the only place to find this species in North America.
Snowcocks live at high elevation among alpine meadows and rocky slopes, feeding on seeds, bulbs, and shoots, and they are considered one of the most challenging upland game birds to hunt because of the steep terrain they prefer.
12. Snowfinch
The White-winged Snowfinch (Montifringilla nivalis) lives at high altitude across the mountains of Europe and Central Asia, far above the treeline, where it forages for seeds and insects near snowfields and alpine huts. Despite the name, it is a sparrow relative rather than a true finch.
Snowfinches often become remarkably tame around mountain ski resorts and refuges, where visitors regularly feed them crumbs, making them one of the easier high-altitude birds to observe up close.
13. Snipe
Wilson’s Snipe (Gallinago delicata) is a stocky, long-billed shorebird that favors wet meadows and marsh edges rather than open mudflats. Its mottled brown plumage provides excellent camouflage among grass and reeds, and the bird typically stays motionless rather than flee when approached.
During courtship flights, male snipe produce an eerie, winnowing sound using specialized tail feathers that vibrate in the wind, a display heard more often than the bird itself is seen.
14. Sandgrouse
The Namaqua Sandgrouse (Pterocles namaqua) lives in the arid regions of southern Africa, where it has adapted to some of the harshest desert conditions any bird tolerates. Males fly dozens of miles each morning to reach water holes, sometimes crossing significant desert distances for a single drink.
Sandgrouse chicks cannot drink on their own, so adult males soak their belly feathers at the water hole and fly them back to the nest, letting chicks drink directly from the wet plumage.
15. Swift
The Chimney Swift (Chaetura pelagica) spends nearly its entire life airborne, only landing to nest or roost, typically inside chimneys and hollow trees across the eastern United States. Its cigar-shaped body and stiff, fluttering wingbeats make it easy to separate from swallows sharing the same sky.
Swifts cannot perch on flat surfaces like most birds because their feet are adapted only for clinging to vertical walls, a trait that shapes everywhere the species can roost or nest.
16. Swiftlet
The Edible-nest Swiftlet (Aerodramus fuciphagus) builds its nest almost entirely from hardened saliva, glued to cave walls across Southeast Asia. That nest is harvested commercially to make bird’s nest soup, a delicacy that has driven significant demand for cave-nesting swiftlet colonies.
Swiftlets navigate the pitch-black interiors of limestone caves using echolocation, a rare ability among birds that is otherwise found mainly in a small number of cave-dwelling species.
17. Shrike
The Loggerhead Shrike (Lanius ludovicianus) is a songbird-sized predator with a hooked bill built for tearing apart insects, lizards, and small rodents. Lacking the strong talons of true raptors, it impales prey on thorns, barbed wire, or sharp twigs to hold it steady while feeding.
This habit has earned shrikes the nickname “butcher bird,” and a shrike’s hunting larder of impaled prey scattered along a fence line is one of the more memorable sights in American grassland birding. Anyone building out a full alphabetical list might also enjoy the birds that start with X, a much shorter but equally strange roster.
18. Starling
The European Starling (Sturnus vulgaris) was introduced to New York’s Central Park in 1890 and has since spread across nearly all of North America, now numbering among the continent’s most abundant songbirds. Its glossy black plumage takes on an iridescent purple-green sheen in good light, speckled with white in winter.
Starlings are gifted mimics and form massive, swirling flocks known as murmurations, a behavior that creates some of the most striking shapes seen in the autumn and winter sky.
19. Shortwing
The White-browed Shortwing (Brachypteryx montana) is a small, secretive songbird found in the dense mountain forests of South and Southeast Asia. True to its name, it has notably short, rounded wings suited to quick, low flights through thick undergrowth rather than long-distance travel.
Shortwings spend most of their time foraging on or near the forest floor, making them a difficult but rewarding find for birders exploring Himalayan foothill trails.
20. Stonechat
The European Stonechat (Saxicola rubicola) is a small, upright perching bird named for its sharp, clicking call, which resembles two stones being tapped together. Males display a striking black head, white neck patch, and orange-washed chest during the breeding season.
Stonechats favor open heathland, hedgerows, and scrubby fields, where they perch conspicuously on low branches or fence posts while scanning the ground for insects.
21. Sunbird
The Scarlet-chested Sunbird (Chalcomitra senegalensis) is one of hundreds of sunbird species across Africa and Asia that fill a similar ecological role to hummingbirds, feeding on nectar with a long, curved bill. Males flash iridescent, orange-tinged wing and throat patches that shift color depending on the angle of the light.
Unlike hummingbirds, sunbirds typically perch while feeding rather than hover, clinging to a flower stem while probing deep into the blossom for nectar and small insects.
22. Silverbill
The African Silverbill (Euodice cantans) is a small, pale brown finch-relative with a distinctive silvery-gray, cone-shaped bill that gives the species its name. It lives in dry grasslands and scrub across sub-Saharan Africa, often in tight, chattering flocks.
Pro Tip: If you keep backyard feeders for finches, silverbills, or siskins, double-check your landscaping against a list of plants that are poisonous to birds before planting new shrubs nearby.
Silverbills feed almost exclusively on grass seed, foraging on the ground in loose, mobile flocks that constantly shift position as they search for fresh seed heads.
23. Sage Grouse
The Greater Sage-Grouse (Centrocercus urophasianus) is the largest grouse species in North America, famous for its elaborate breeding display in which males inflate bright yellow air sacs on their chest while fanning spiky tail feathers. These communal display grounds, called leks, draw multiple males competing for female attention each spring.
Sage-grouse depend entirely on sagebrush habitat across the western United States, both for food and shelter, which makes the species a key indicator of rangeland health across the Great Basin and Rocky Mountain states.
24. Shoebill Stork
The Shoebill Stork (Balaeniceps rex) is instantly recognizable by its enormous, pale yellow bill shaped like a wooden clog, ending in a sharp, curved hook. Wikipedia notes that the species was first described by naturalist John Gould in 1850 and remains the only living member of its own family, Balaenicipitidae, separate from true storks.
The bird stands roughly 110 to 140 centimeters tall and lives in the papyrus swamps of east-central Africa, including South Sudan, Uganda, and Zambia. Its feet feature long, unwebbed toes that spread the bird’s weight evenly across floating vegetation, letting it stand motionless for long stretches while stalking fish. Few birds with weird names live up to the label quite like this one, whose scientific classification is still a bit of a puzzle to ornithologists.
The Shoebill Stork is currently rated Vulnerable by the IUCN, with an estimated wild population of only a few thousand individuals.
25. Snowy Owl
The Snowy Owl (Bubo scandiacus) breeds on the Arctic tundra and occasionally ventures far south into the northern United States during winters when lemming populations crash in its usual range. Adult males are almost pure white, while females and juveniles carry heavy dark barring across the back and wings.
- Large, rounded head with no visible ear tufts
- Bird with big eyes adapted for low-light Arctic hunting
- Bright yellow eyes and a dark, almost hidden bill
- Often hunts during daylight, unlike most owl species
Unlike most owls, Snowy Owls frequently hunt in open daylight, a habit tied to the nearly continuous daylight of Arctic summers where they breed.
26. Smith’s Longspur
Smith’s Longspur (Calcarius pictus) is a sparrow-sized songbird that breeds on the Arctic tundra of northern Canada and Alaska, then winters in short-grass prairies of the south-central United States. Breeding males show a bold black-and-white face pattern against a buffy-orange underside.
This species has an unusual mating system in which females often mate with several males in a single season, and multiple males may help provision the same nest, a rare arrangement among North American songbirds.
27. Smooth-Billed Ani
The Smooth-billed Ani (Crotophaga ani) is an all-black, long-tailed bird related to cuckoos, found in South Florida and throughout much of Central and South America. Its thick, curved bill looks almost comically oversized for its body, giving the species an unmistakable silhouette.
Anis are unusually social nesters, with several breeding pairs sometimes sharing a single nest and taking turns incubating a combined clutch of eggs, a cooperative strategy rarely seen outside this genus.
28. Sedge Wren
The Sedge Wren (Cistothorus platensis) is a tiny, secretive songbird of wet meadows and sedge marshes, far more often heard than seen as it scurries low through dense grass. Its song is a dry, staccato chatter quite different from the louder, more melodic song of its close relative, the Marsh Wren.
Sedge Wrens are unusually nomadic for a songbird, frequently shifting breeding territory from one year to the next depending on how wet a given meadow is that season.
29. Semipalmated Plover
The Semipalmated Plover (Charadrius semipalmatus) is a small, round shorebird with a single dark breast band, named for the partial webbing between its toes that aids walking on soft mud. It breeds across the Canadian Arctic and migrates through beaches and mudflats on both US coasts.
Like many plovers, it hunts using a run-stop-peck pattern, dashing forward across open mud before freezing to snatch up a worm or small crustacean it has spotted.
30. Snowy Plover
The Snowy Plover (Charadrius nivosus) is a pale, sand-colored shorebird that nests directly on open beaches and alkaline flats across the western and Gulf Coast United States. Its coloring blends almost seamlessly with dry sand, which also makes its nests highly vulnerable to foot traffic and off-leash dogs.
Key Insight: Beach-nesting species like the Snowy Plover rely on roped-off dune areas during spring and summer. Giving posted nesting zones a wide berth is one of the simplest ways beachgoers can protect the species.
Because of ongoing habitat loss along developed coastlines, several Snowy Plover populations are protected under state and federal conservation programs.
31. Siskin
The Pine Siskin (Spinus pinus) is a small, heavily streaked finch with a thin, pointed bill and flashes of yellow in the wings and tail. It travels in unpredictable, nomadic flocks that can show up in large numbers at feeders one winter and disappear entirely the next.
Birders tracking the full range of small songbird names often cross-reference the bird names that start with I, since several Icterid relatives share similar feeder habits with siskins.
32. Seriema
The Red-legged Seriema (Cariama cristata) is a tall, long-legged bird of South American grasslands that looks and behaves something like a small, terrestrial raptor. It rarely flies, preferring to run down lizards, snakes, and large insects across open savanna.
Seriemas are considered the closest living relatives of the extinct “terror birds,” giant flightless predators that once dominated South America, making this species a living link to a very different era.
33. Sapphire
“Sapphire” is the common name given to several hummingbird species in the genus Hylocharis, found throughout Central and South America. The White-chinned Sapphire displays brilliant, iridescent blue-green plumage that shifts dramatically depending on the viewing angle, a trait shared across most sapphire hummingbirds.
Like other hummingbirds, sapphires feed almost continuously throughout the day, visiting hundreds of flowers to meet the extreme metabolic demands of hovering flight.
34. Sanderling
The Sanderling (Calidris alba) is the small, pale shorebird most people picture when they think of birds chasing waves up and down a beach. It breeds in the High Arctic but spends most of the year running along sandy shorelines on nearly every continent except Antarctica.
- Watch the wave line, not the open sand, where Sanderlings concentrate their feeding
- Look for the pale, almost white winter plumage compared to the rustier breeding colors
- Note the stout, black bill and legs, which help separate it from other small “peep” sandpipers
35. Secretary Bird
The Secretary Bird (Sagittarius serpentarius) is a large African raptor named for the crest of long feathers on the back of its head, which resemble the quill pens 19th-century clerks once tucked behind their ears. Its scientific name translates to roughly “the archer of snakes,” reflecting its reputation as a skilled hunter of venomous snakes across sub-Saharan Africa.
Unlike nearly every other raptor, the Secretary Bird hunts almost entirely on foot, striding across open grassland and savanna to stomp prey to death with its powerful legs. The Peregrine Fund notes that Secretarybirds have the longest legs of any living bird of prey, a trait that forces the bird into an awkward crouch whenever it needs to feed or drink.
Important Note: Conservation assessments for the Secretary Bird vary by source. National Geographic lists the species as Vulnerable, while the Peregrine Fund classifies it as Endangered, reflecting rapid population declines tied to habitat loss across its African range.
36. Saker Falcon
The Saker Falcon (Falco cherrug) is a powerful, long-winged falcon of the open steppe and semi-desert regions of Central Asia and Eastern Europe. It is larger and paler than the more familiar Peregrine Falcon, with a build adapted for chasing prey over long, open stretches of grassland rather than diving from great heights.
Saker Falcons have held major cultural importance in falconry across the Middle East and Central Asia for centuries, and that demand has contributed to population pressure on wild populations in parts of its range.
37. Scrub Jay
The Florida Scrub-Jay (Aphelocoma coerulescens) is found nowhere else on Earth, restricted to the shrinking scrub oak habitat of central Florida. Its western counterpart, the California Scrub-Jay, is more widespread but shares the same bright blue head, wings, and tail against a gray-brown back.
Scrub-jays live in cooperative family groups, with young birds often staying near their parents for a year or more to help defend territory and raise the next brood, an unusually social arrangement for a jay.
38. Skua
The Great Skua (Stercorarius skua) is a heavily built, aggressive seabird that breeds on subarctic and Arctic islands and is infamous for stealing food directly from other birds, a behavior called kleptoparasitism. It will even attack birds many times its own size to force them to drop a freshly caught fish.
Skuas also prey directly on the eggs and chicks of nesting seabirds, making them one of the more feared predators around any coastal colony. Readers tracking species by letter sometimes pair this entry with the bird names that start with K, since several seabird relatives share the same aggressive foraging habits.
39. Screech Owl
The Eastern Screech-Owl (Megascops asio) is a small, compact owl found in woodlands, parks, and even suburban yards across the eastern United States. It comes in two main color variations, gray and reddish-brown, and both can occur in the same local population regardless of habitat.
Despite its name, the Eastern Screech-Owl’s actual call is a soft, descending trill or whinny rather than a true screech, often mistaken by beginning birders for a completely different species.
40. Sora
The Sora (Porzana carolina) is a small, chicken-shaped marsh bird with a short yellow bill and a habit of staying hidden among dense cattails and reeds. It is far more often heard than seen, giving a distinctive, descending whinny call across wetlands throughout much of North America.
Soras are surprisingly strong migrants for such a small, secretive bird, traveling thousands of miles between northern marshes and wintering grounds as far south as northern South America.
41. Skimmer
The Black Skimmer (Rynchops niger) has one of the most unusual bills in the bird world, with a lower mandible noticeably longer than the upper one. Its bright red bill, tipped in black, is unmistakable as it flies low over calm water.
Skimmers feed by flying just above the water’s surface and dragging the lower half of their bill through it, snapping shut the instant it contacts a small fish, a feeding method unique among North American birds.
42. Spinetail
Spinetails are a large group of small, active songbirds in the genus Synallaxis, found throughout Central and South America in dense scrub and forest undergrowth. Most species are brownish or rufous overall, with the stiff, pointed tail feathers that give the group its common name.
Spinetails tend to stay low and well hidden, more often identified by their sharp, repetitive call notes than by a clear visual sighting, which makes them a frequent challenge for birders working through South American checklists.
43. Sooty Tern
The Sooty Tern (Onychoprion fuscatus) is a striking black-and-white seabird that nests in enormous colonies on tropical islands, including the Dry Tortugas off the Florida Keys. Adults have a sharply defined black cap and upperparts against a crisp white forehead and underside.
Young Sooty Terns spend their first several years almost entirely at sea without ever landing, a behavior that keeps juveniles airborne or resting on water for an extraordinarily long stretch before they return to breed. Anyone who has worked through this entire list might round things out with the bird names that start with Z for a quick change of pace.
| Bird | Typical Habitat | Notable Feature |
|---|---|---|
| Sparrow | Urban areas, grasslands, brush | Short, conical seed-cracking bill |
| Starling | Cities, farmland, open country | Iridescent plumage, flock murmurations |
| Swallow | Open fields, barns, bridges | Forked tail, aerial insect hunting |
| Swift | Chimneys, hollow trees, open sky | Cannot perch on flat surfaces |
| Swan | Lakes, rivers, ponds | All-white body with long neck |
| Species | Range | Primary Diet |
|---|---|---|
| Sage Grouse | Western US sagebrush steppe | Sagebrush leaves, insects |
| Secretary Bird | Sub-Saharan Africa | Snakes, rodents, insects |
| Saker Falcon | Central Asia, Eastern Europe | Small mammals, birds |
| Snowy Owl | Arctic tundra, winters south | Lemmings, small mammals, birds |
| Screech Owl | Eastern US woodlands | Insects, small rodents |
Forty-three species is a lot of ground to cover, but a few patterns repeat throughout this list: bill shape almost always signals diet, leg length tracks habitat, and plumage color often shifts dramatically between breeding and winter season. Those three checkpoints apply just as well to bird names that start with S as they do to any other letter in the alphabet.
Birders building a complete reference often branch out from here, comparing this list against birds starting with the letter A or working letter by letter through a full A bird species list to round out their identification skills across every habitat and family.
