Direct answer: The current AviList global checklist (v2025b) recognizes 11,131 bird species in 46 orders and 252 families. “Type of bird” is an informal phrase: it can mean a species, a family, an ecological group, or even a sex or age term such as rooster or hen. This guide explains 40 familiar bird names with pictures, identification clues, habitats, diets, taxonomy, and conservation context.

Taxonomy and conservation facts last reviewed in August 2026.

Key takeaways

Birds are defined by feathers; all living species also have beaks, lay hard-shelled eggs, and descend from theropod dinosaurs.
Common names do not always match taxonomy. Pigeons and doves share one family, while Old World and New World sparrows belong to different families.
Some entries, including rooster and hen, describe sex or life stage rather than a separate species.
Conservation status should be checked at species or population level. A familiar bird group can contain both abundant and highly threatened species.

What does “type of bird” mean?

In biology, a species is a formally recognized unit, while orders and families group related species. Everyday labels such as “raptor,” “waterfowl,” “gamebird,” and “seabird” are useful because they describe ecology or body form, but they may combine birds that are not each other’s closest relatives.

This article therefore treats “type” as a reader-friendly label. Each entry identifies the most relevant scientific group and flags cases where a familiar word is informal, misleading, or shared by unrelated birds.

Main bird categories at a glance

Practical category	Typical clues	Examples in this guide
Perching birds and songbirds	Feet adapted to perching; highly varied bills and songs	Cardinal, sparrow, nightingale, goldfinch, robin
Raptors and scavengers	Hooked bills; strong feet or specialized carrion feeding	Eagle, hawk, owl, vulture
Waterfowl	Aquatic habits; webbed feet in most species	Duck, goose, swan
Wading and wetland birds	Long legs, necks, or bills for shallow-water feeding	Flamingo, spoonbill, crane
Seabirds	Marine feeding, coastal colonies, or diving adaptations	Gull, puffin, penguin, cormorant, pelican
Ground and game birds	Heavy bodies, camouflage, and short bursts of flight	Turkey, quail, pheasant, partridge
Flightless specialists	Reduced flight ability and strong swimming or running adaptations	Penguin, ostrich, kiwi

Practical bird categories overlap and do not replace formal taxonomy.

How to identify an unfamiliar bird

Begin with structure and behavior before focusing on color. Plumage can change with age, sex, season, light, and wear, while a bird’s habitat, shape, and movement often narrow the possibilities faster.

Estimate size and silhouette: Compare the bird with a familiar species and note body shape, neck length, wing shape, and tail shape.
Study the bill and feet: These structures often reveal whether a bird catches fish, cracks seeds, probes mud, climbs bark, or grips prey.
Watch behavior: Record how it flies, forages, swims, perches, walks, or interacts with other birds.
Note habitat, place, and season: Range and migration timing can eliminate many lookalikes.
Listen: Calls and songs can be more diagnostic than plumage.
Use several clues together: A single color patch is rarely enough for a reliable identification.

Tree, aerial, and nectar specialists

These birds show how wings, bills, feet, and feeding behavior can become specialized for bark, open air, water, flowers, or unusual breeding strategies.

1. Woodpecker

Two woodpeckers clinging to a tree trunk — Woodpeckers use stiff tail feathers and specialized feet to brace against tree trunks.

Woodpeckers are tree-climbing birds in the family Picidae. Most have strong, chisel-like bills, two toes pointing forward and two backward, and stiff tail feathers that support the body while climbing. They eat insects, fruit, sap, seeds, and other foods depending on the species.

Known for: Drumming, excavating nest cavities, and probing bark for food.
Representative species: Downy Woodpecker, Pileated Woodpecker, and Red-headed Woodpecker.
Conservation note: The Red-cockaded Woodpecker was reclassified from endangered to threatened under the U.S. Endangered Species Act in 2024, but it still depends on actively managed mature pine habitat.

2. Swallow

Swallows flying through the air — Swallows have streamlined bodies and pointed wings suited to catching insects in flight.

Swallows are aerial insect-eaters in the family Hirundinidae. Their slim bodies, pointed wings, and wide mouths help them catch small insects while flying over fields, wetlands, towns, and open water. Many species migrate between breeding and wintering areas.

Known for: Fast, agile flight and feeding on airborne insects.
Representative species: Barn Swallow, Tree Swallow, and Bank Swallow.
Easy comparison: Swallows can perch normally; swifts have different feet and spend even more of their lives in the air.

3. Kingfisher

Kingfisher perched on a branch — Many kingfishers hunt from perches, but not every species specializes in fish.

Kingfishers belong to the family Alcedinidae. Many species watch from a branch before diving for fish, but forest kingfishers may eat insects, lizards, frogs, or small mammals instead. Their heavy, pointed bills and compact bodies are more consistent identifiers than habitat alone.

Known for: Rapid plunge-dives, loud calls, and bright blue, green, or chestnut plumage in many species.
Representative species: Belted Kingfisher, Common Kingfisher, and Laughing Kookaburra.
Habitat: Rivers, lakes, coasts, mangroves, forests, and savannas, depending on the species.

4. Hummingbird

Hummingbird feeding from a yellow flower — Hummingbirds occur only in the Americas and can hover while feeding.

Hummingbirds are small birds in the family Trochilidae, found only in the Americas. Their shoulder joints and rapid wingbeats allow sustained hovering, backward flight, and precise movement around flowers. Nectar supplies energy, while insects and spiders provide protein and other nutrients.

Known for: Hovering flight, iridescent feathers, and long bills adapted to different flower shapes.
Representative species: Ruby-throated Hummingbird, Anna’s Hummingbird, and Bee Hummingbird.
Conservation action: Native flowering plants and pesticide reduction can improve feeding habitat for local species.

5. Cuckoo

Cuckoo perched on a tree branch — Only some cuckoo species lay their eggs in the nests of other birds.

Cuckoos form the family Cuculidae and occur on every continent except Antarctica. The group includes slender, tree-dwelling cuckoos, ground cuckoos, coucals, anis, and roadrunners. Brood parasitism is famous in the Common Cuckoo, but many cuckoos build nests and raise their own young.

Known for: Repeated calls, long tails, and varied breeding strategies.
Diet: Mostly insects, with fruit and small vertebrates taken by some species.
Representative species: Common Cuckoo, Greater Roadrunner, and Smooth-billed Ani.

Pigeons, parrots, and ornamental birds

This group includes familiar birds whose common names are often confused with formal taxonomy, especially pigeons, doves, and peafowl.

6. Pigeon

Pigeons perched along the edge of a building — Pigeons and doves belong to the same bird family, Columbidae.

Pigeons are members of Columbidae, the same family as doves. “Pigeon” often refers to larger, heavier members of the family, but there is no strict scientific boundary between the two names. Rock Pigeons are the familiar city birds from which domestic and homing breeds were developed.

Known for: Strong flight, head-bobbing walks, and the ability of some breeds to return home over long distances.
Family trait: Both parents can produce nutrient-rich crop milk for their chicks.
Representative species: Rock Pigeon, Band-tailed Pigeon, and Victoria Crowned Pigeon.

7. Dove

Two doves perched on a tree branch — The word dove usually describes smaller Columbidae, but the naming rule is informal.

Doves are also members of Columbidae. The name is commonly applied to smaller or more slender species, although common names do not follow a consistent taxonomic rule. Many doves feed on seeds and fruit and help move seeds through forests, grasslands, farms, and urban areas.

Known for: Soft cooing calls, compact bodies, and fast direct flight.
Representative species: Mourning Dove, Eurasian Collared-Dove, and Inca Dove.
Identification tip: Look at tail shape, wing pattern, neck markings, and call rather than relying on color alone.

8. Parrot

Colorful parrots perched on a branch — Parrots combine hooked bills with two forward-facing and two backward-facing toes.

Parrots belong to the order Psittaciformes. They have strong curved bills, grasping feet, and flexible tongues that help them handle seeds, nuts, fruit, flowers, and other foods. Intelligence and vocal learning are well developed in many species, but behavior and care requirements vary widely.

Known for: Complex social behavior, problem-solving, and vocal mimicry in some species.
Representative species: Budgerigar, African Grey Parrot, macaws, cockatoos, and kea.
Conservation note: Habitat loss and illegal or unsustainable trade threaten many wild populations; responsible ownership requires legal sourcing and long-term care.

9. Peacock

Male Indian peafowl displaying blue and green plumage — A peacock is a male peafowl; a female is a peahen.

“Peacock” correctly refers to a male peafowl. Females are peahens, and the birds collectively are peafowl. Three living species are recognized: Indian Peafowl, Green Peafowl, and Congo Peafowl. Males use elongated upper-tail coverts, often called a train, in courtship displays.

Known for: Eye-spotted display feathers, loud calls, and strong sexual dimorphism.
Native range: South and Southeast Asia for Indian and Green Peafowl; the Congo Basin for Congo Peafowl.
Conservation note: Green Peafowl is classified as Endangered and remains vulnerable to habitat loss, hunting, and trade.

Domestic and game birds

Several entries here are domestic sex terms or informal groups rather than distinct branches on the bird family tree.

10. Rooster

Three roosters standing together — Rooster is the term for an adult male domestic chicken, not a separate species.

A rooster is an adult male domestic chicken. Roosters crow throughout the day, not only at sunrise, and may use calls and displays to advertise territory, warn the flock, and signal food. Comb shape, body size, plumage, and temperament differ among breeds.

Scientific context: Roosters and hens are domestic chickens, generally treated as the domesticated form of the Red Junglefowl.
Flock role: Males may guard hens, maintain social position, and fertilize eggs.
Conservation context: Maintaining heritage breeds helps preserve domestic genetic diversity, but husbandry should also prioritize animal welfare.

11. Hen

Hens perched on a tree branch — Hen usually means an adult female chicken, although the term can apply to females of other birds.

A hen is an adult female bird; in everyday use, the word most often means a female domestic chicken. Egg-laying age, frequency, shell color, body size, and broodiness depend on genetics, health, daylight, nutrition, and living conditions. A hen does not need a rooster to lay eggs, but a rooster is needed for the eggs to be fertilized.

Known for: Egg laying, nesting behavior, and a structured flock hierarchy.
Breed variation: Ameraucanas can lay blue eggs, while many commercial lines are selected for high production.
Care note: Clean housing, appropriate nutrition, veterinary care, and opportunities for natural behavior support welfare.

12. Turkey

Wild turkey standing in grass — Wild Turkeys are native to North America; the related Ocellated Turkey lives on the Yucatán Peninsula.

Turkeys are large gamebirds in the genus Meleagris. The Wild Turkey (M. gallopavo) is native to North America, while the Ocellated Turkey (M. ocellata) occurs on the Yucatán Peninsula and nearby areas. Domestic turkeys descend from populations of Wild Turkey.

Known for: Fan-shaped tails, bare head and neck skin, and male display structures such as the snood and wattles.
Diet: Seeds, nuts, fruit, shoots, insects, and other small animals.
Habitat: Woodlands mixed with clearings, farms, savannas, and scrub, depending on the species and region.

13. Quail

Quail walking through tall grass — Quail is a common name used for several compact, ground-dwelling bird groups.

Quail are small, round-bodied gamebirds, but the name covers more than one lineage. Old World quail belong to Phasianidae, while New World quail belong to Odontophoridae. Most stay close to cover, forage on the ground, and rely on camouflage before making a short, explosive flight.

Known for: Short tails, mottled plumage, and whistled or repeated calls.
Representative species: Common Quail, Northern Bobwhite, and California Quail.
Conservation note: Grassland conversion, intensive agriculture, and loss of field edges can reduce suitable habitat.

14. Pheasant

Male pheasants with colorful plumage — Male pheasants are often more colorful than females, which benefit from camouflage while nesting.

Pheasants are mostly ground-dwelling birds in the family Phasianidae. The Common Pheasant originated in Asia but has been introduced widely in Europe and North America. Many species show strong sexual dimorphism, with ornate males and cryptically colored females.

Known for: Long tails, short bursts of flight, and elaborate male displays.
Representative species: Common Pheasant, Golden Pheasant, and Reeves’s Pheasant.
Conservation note: Status varies sharply; some introduced populations are abundant, while species such as Reeves’s Pheasant face habitat loss and hunting pressure.

15. Partridge

Three partridges resting in grass — Partridge is an informal name for several compact gamebirds, mainly in the pheasant family.

Partridges are medium-sized, ground-oriented gamebirds, mainly within Phasianidae. They tend to have plump bodies, short rounded wings, and camouflage suited to grassland, scrub, farmland, or rocky slopes. The name describes a practical group rather than one single evolutionary branch.

Representative species: Gray Partridge, Chukar, and Red-legged Partridge.
Diet: Seeds, leaves, shoots, and insects, especially for growing chicks.
Conservation note: Some populations decline where intensive farming removes hedges, field margins, and insect-rich cover.

Raptors and scavengers

Birds of prey and scavengers occupy different feeding niches. Hooked bills are common, but hunting style, foot structure, and evolutionary history vary.

16. Vulture

Black vultures soaring in flight — New World and Old World vultures evolved similar scavenging roles in separate lineages.

Vultures are large scavenging birds that locate and consume carcasses. New World vultures belong to Cathartidae, while Old World vultures are part of Accipitridae. Their ecological role is unusually important: rapid carcass removal can limit access for feral dogs and other animals that may spread disease.

Known for: Broad soaring wings, bare or sparsely feathered heads in many species, and highly acidic digestive systems.
Representative species: Turkey Vulture, Black Vulture, Griffon Vulture, and Bearded Vulture.
Conservation note: Poisoning, veterinary drugs, collisions, reduced food, and persecution have caused severe declines; the White-rumped Vulture is Critically Endangered.

17. Eagle

Eagle standing on a rock — Eagle is a common name for several large raptor lineages in the family Accipitridae.

Eagles are generally large, powerful birds of prey in Accipitridae. The name is used across several lineages, including sea eagles, booted eagles, snake eagles, and harpy eagles, so there is no single body plan shared by every bird called an eagle. All have strong talons and hooked bills for handling prey or carrion.

Known for: Broad wings, strong feet, and sharp distance vision.
Representative species: Bald Eagle, Golden Eagle, Harpy Eagle, and White-bellied Sea-Eagle.
Conservation note: Major threats include habitat loss, poisoning, electrocution, collisions, and direct persecution, depending on the species.

18. Owl

Owl perched in a tree at night — Most owls are active at night, but some species hunt during daylight or at dawn and dusk.

Owls belong to the order Strigiformes, divided into barn owls and typical owls. Their forward-facing eyes, facial discs, flexible necks, and quiet flight support hunting in low light. Some species have asymmetrical ear openings that help pinpoint sound, although this feature is not universal.

Known for: Silent flight, powerful feet, regurgitated pellets, and head rotation of up to about 270 degrees.
Representative species: Barn Owl, Great Horned Owl, Elf Owl, and Great Gray Owl.
Ecological role: Owls regulate populations of rodents, insects, and other prey and depend on suitable habitat for nesting and hunting.

19. Hawk

Hawk flying above a mountain landscape — Hawk is a broad common name, not a formal taxonomic category.

“Hawk” is applied to many medium-sized raptors in Accipitridae. In North America, broad-winged soaring species such as the Red-tailed Hawk are often called buteos, while forest hunters such as Cooper’s Hawk are accipiters. Common names differ by region, so identification should rely on shape, flight style, plumage, voice, and range.

Known for: Hooked bills, gripping talons, and strong vision.
Representative species: Red-tailed Hawk, Cooper’s Hawk, and Sharp-shinned Hawk.
Conservation note: Threats can include habitat change, poisoning, vehicle strikes, and collisions with windows or infrastructure.

Songbirds and corvids

Passerines make up the largest bird order. This section includes seed-eaters, thrushes, Old World flycatchers, and highly adaptable corvids.

20. Cardinal

Two northern cardinals perched on branches — Male Northern Cardinals are bright red; females are warm brown with red accents.

Cardinals are songbirds in the family Cardinalidae, a broader group that also contains grosbeaks, buntings, and other birds. The Northern Cardinal is the best-known example: males are red, females are mostly brown, and both sexes have a crest and thick seed-cracking bill.

Known for: Clear whistled songs, territorial pairs, and year-round residence across much of the range.
Representative species: Northern Cardinal, Vermilion Cardinal, and Pyrrhuloxia.
Habitat: Woodland edges, scrub, gardens, parks, and dense suburban vegetation.

21. Magpie

Magpies perched in a tree — Not every magpie is black and white; the common name spans several corvid genera.

Magpies are long-tailed members of the crow family, Corvidae, but the name covers several genera in Europe, Asia, Africa, and North America. Many are black and white, while green and blue magpies can be brightly colored. They are adaptable omnivores with complex social behavior.

Known for: Long tails, varied calls, food caching, and problem-solving.
Representative species: Eurasian Magpie, Black-billed Magpie, and Taiwan Blue Magpie.
Diet: Insects, seeds, fruit, carrion, eggs, and small animals, depending on season and opportunity.

22. Sparrow

Three sparrows perched on a tree branch — Old World and New World sparrows look similar but belong to different bird families.

“Sparrow” refers to two major groups that are not close relatives. Old World sparrows are in Passeridae; New World sparrows are in Passerellidae. Both include many small brown or streaked birds with conical bills, but plumage, song, habitat, and behavior provide better identification clues.

Representative species: House Sparrow, Eurasian Tree Sparrow, Song Sparrow, and White-crowned Sparrow.
Diet: Seeds, buds, fruit, and insects; nestlings often receive protein-rich invertebrates.
Identification tip: Compare head stripes, breast markings, tail length, song, and geographic range.

23. Crow

Black crow perched on a tree branch — Crows and ravens share the genus Corvus, and their common names do not create a precise scientific split.

Crows are intelligent, social birds in the genus Corvus. Many live successfully in farms, forests, coasts, and cities, where they exploit varied foods and learn from other birds. Tool use has been documented in some crow species, but abilities differ among populations and contexts.

Known for: Harsh calls, communal roosts, food caching, and flexible problem-solving.
Representative species: American Crow, Carrion Crow, and Hooded Crow.
Identification tip: Voice, bill shape, tail shape, flight style, and local range are usually more reliable than size alone.

24. Raven

Three ravens perched together — Common Ravens usually look heavier than nearby crows and often show a wedge-shaped tail in flight.

Ravens are large members of Corvus. The Common Raven has a heavy bill, shaggy throat feathers, long wings, and a wedge-shaped tail, but these field marks should be considered together. Ravens are strong fliers that soar, tumble, cache food, and use a wide range of natural and human-altered habitats.

Known for: Deep croaking calls, aerial play, pair bonds, and sophisticated social learning.
Representative species: Common Raven, Chihuahuan Raven, and Australian Raven.
Comparison: Use the detailed crow versus raven identification guide for side-by-side field marks.

25. Nightingale

Nightingale perched on a branch under a full moon — The Common Nightingale is visually understated but produces a powerful, varied song.

The Common Nightingale (Luscinia megarhynchos) is an Old World flycatcher rather than a thrush. It breeds in parts of Europe, North Africa, and western Asia, then migrates to sub-Saharan Africa. Males may sing by day or night, using repeated whistles, trills, and rising or falling phrases.

Known for: Complex song and secretive behavior in dense vegetation.
Appearance: Warm brown upperparts, a reddish tail, and pale underparts.
Diet: Mostly insects and other invertebrates, with berries and fruit taken seasonally.

26. Goldfinch

American goldfinch perched near sunflowers — American Goldfinches are seed specialists and often feed from thistles and sunflowers.

Goldfinch is a common name used for several finches, including the American Goldfinch in genus Spinus and the European Goldfinch in genus Carduelis. In the United States, American, Lesser, and Lawrence’s Goldfinches can be separated by head pattern, back color, wing markings, range, and call.

Known for: Undulating flight, small conical bills, and a strong preference for seeds.
Seasonal change: Male American Goldfinches molt from bright breeding plumage into duller winter colors.
Habitat: Weedy fields, open woodland, gardens, roadsides, and areas with seed-producing plants.

27. Robin

European robin standing among autumn leaves — The pictured European Robin is not closely related to the larger American Robin.

“Robin” is a shared common name, not a single taxonomic group. The American Robin (Turdus migratorius) is a large thrush with gray-brown upperparts and a warm orange belly. The smaller European Robin (Erithacus rubecula), shown here, is an Old World flycatcher with an orange-red face and breast.

American Robin: A North American thrush common on lawns, parks, farms, and woodland edges.
European Robin: An Old World flycatcher common in gardens, parks, hedges, and woodland across much of Europe.
Why the shared name: European settlers applied “robin” to the American species because both birds have orange-red underparts, despite being unrelated at the family level.

Waterfowl and wetland birds

Aquatic birds use different parts of the water column and shoreline. Protecting wetland ecosystems therefore supports feeding, nesting, migration, and water quality for many species at once.

28. Duck

Ducks resting in a wetland — Ducks include dabbling, diving, sea, and perching species with different feeding strategies.

Ducks are waterfowl in the family Anatidae, alongside geese and swans. “Duck” is a practical common-name group rather than a single formal branch. Species range from surface-feeding dabblers to deep-diving sea ducks, and some spend substantial time in forests or grasslands.

Known for: Waterproofed plumage, webbed feet in most species, and bills adapted to different foods.
Representative species: Mallard, Wood Duck, Common Eider, and Canvasback.
Conservation note: Wetland drainage, pollution, invasive species, lead exposure, and unsustainable harvest can affect populations.

29. Pelican

Pelicans swimming on a lake — A pelican’s throat pouch helps scoop prey and drain water before swallowing.

Pelicans are large waterbirds in the family Pelecanidae. Their expandable throat pouch is a fishing tool, not a long-term storage bag. Feeding methods differ: Brown Pelicans plunge-dive from the air, while several white pelican species herd fish cooperatively in shallow water.

Known for: Long bills, large pouches, broad wings, and communal roosting or nesting.
Species count: Eight living pelican species are recognized.
Habitat: Coasts, estuaries, rivers, lakes, lagoons, and reservoirs.

30. Spoonbill

Spoonbills wading along a riverbank — Spoonbills sweep their flattened bills through shallow water to detect prey by touch.

Spoonbills are six species of long-legged wading birds in genus Platalea, within the ibis family Threskiornithidae. They feed by moving the partly open bill from side to side through shallow water. Sensitive structures in the bill help detect fish, crustaceans, insects, and other small prey.

Known for: Flat, spoon-shaped bill tips and sweeping foraging movements.
Representative species: Roseate Spoonbill, Eurasian Spoonbill, and African Spoonbill.
Conservation note: Healthy wetlands require suitable water levels, clean water, feeding areas, and secure nesting sites.

31. Crane

Cranes flying over a shoreline at sunset — Cranes use loud calls and ritualized movements to communicate and reinforce pair or family bonds.

Cranes are tall birds in the family Gruidae. Unlike herons, they usually fly with their necks extended. They use wetlands, grasslands, agricultural areas, and open woodland, depending on the species, and many make long seasonal migrations.

Known for: Trumpeting calls, synchronized dances, long legs, and extended-neck flight.
Diversity: There are 15 crane species worldwide.
Conservation note: The International Crane Foundation reports that 10 of the 15 species are threatened with extinction, with habitat loss, poisoning, hunting, and infrastructure among the pressures.

32. Cormorant

Cormorant holding its wings open above the water — Cormorants often spread their wings after diving, a posture linked to feather drying and heat balance.

Cormorants and shags form the family Phalacrocoracidae. They pursue fish underwater, propelled mainly by their feet, and surface with a low profile. Many have dark plumage, but color, facial skin, crests, and body size vary considerably among the 34 recognized species.

Known for: Hooked bill tips, strong swimming, colony nesting, and wing-spreading postures.
Habitat: Coasts, estuaries, rivers, lakes, and reservoirs.
Conservation note: Fishing-gear entanglement, disturbance, pollution, and conflict with fisheries can affect local populations.

33. Swan

Two swans swimming on a lake — Swans often form long-term pair bonds, but “mate for life” is not an absolute rule.

Swans are the largest waterfowl in genus Cygnus, within Anatidae. Their long necks help them reach aquatic plants and invertebrates below the surface. Adults of several northern species are white, while Black Swans and Black-necked Swans show that swans are not uniformly white.

Representative species: Trumpeter Swan, Tundra Swan, Whooper Swan, Mute Swan, and Black Swan.
Known for: Powerful flight, strong territorial behavior during breeding, and long-term pair bonds in many pairs.
Conservation context: Management needs differ by region; a native protected species in one place may be introduced or invasive in another.

34. Flamingo

Flamingos gathered beside a lake at sunset — Flamingo color comes from carotenoid pigments obtained through food.

Flamingos are six species of filter-feeding waders in Phoenicopteridae. They feed with the bill held upside down, using comb-like structures called lamellae to separate food from water and mud. Their pink, orange, or crimson color develops from carotenoids in algae and small aquatic animals.

Known for: Long legs and necks, bent bills, synchronized group displays, and large colonies.
Representative species: Greater Flamingo, American Flamingo, Lesser Flamingo, and Andean Flamingo.
Conservation note: Water diversion, mining, disturbance, pollution, and changing lake conditions can threaten breeding and feeding sites.

35. Goose

Flock of geese flying in formation — Many geese migrate in formations, although some species or populations remain resident.

Geese are medium-to-large waterfowl in Anatidae. The common name covers several genera rather than one single lineage. They often graze on grasses and aquatic plants, but diets may also include seeds, roots, insects, and other small animals.

Known for: Loud calls, strong family groups, seasonal movements, and formation flight.
Representative species: Canada Goose, Snow Goose, Brant, Greylag Goose, and Barnacle Goose.
Conservation context: Some populations have recovered or expanded, while others depend on protected Arctic breeding grounds, wetlands, and migration stopovers.

Seabirds and flightless specialists

This final group includes marine birds and birds that traded powered flight for stronger running or swimming. For another ocean specialist, see the Wandering Albatross.

36. Gull (often called a seagull)

Gulls taking flight above the water — “Seagull” is informal: many gull species live and feed far inland.

Gulls are adaptable waterbirds in the family Laridae. “Seagull” is a familiar but imprecise name because many species regularly occupy lakes, rivers, farmland, parking lots, and cities. Plumage changes with age and season, which can make gull identification difficult even for experienced birders.

Known for: Long wings, webbed feet, varied calls, and opportunistic feeding.
Representative species: Herring Gull, Ring-billed Gull, Laughing Gull, and Great Black-backed Gull.
Identification tip: Record body size, bill color, leg color, wingtip pattern, head streaking, age, and location.

37. Puffin

Atlantic puffin standing on coastal rocks — The Atlantic, Horned, and Tufted Puffins are the three true puffin species.

Puffins are compact seabirds in genus Fratercula, within the auk family Alcidae. Their wings power both flight in air and pursuit underwater. Bright bill plates develop for the breeding season and become duller after the outer layers are shed.

True puffin species: Atlantic Puffin, Horned Puffin, and Tufted Puffin.
Nesting: Burrows or rock crevices on islands and sea cliffs, often in dense colonies.
Conservation note: The Atlantic Puffin is globally Vulnerable; warming seas, prey shifts, extreme weather, fishing pressure, pollution, and introduced predators can reduce breeding success.

38. Penguin

Group of penguins standing on snow — Penguins are Southern Hemisphere birds; wild penguins do not live in the Arctic.

Penguins are 19 species of flightless seabirds in Spheniscidae. Their wings have become stiff flippers, their dense bones reduce buoyancy, and their streamlined bodies support efficient underwater pursuit. Most penguin species live outside Antarctica, including temperate and subtropical coasts.

Known for: Countershaded plumage, upright movement on land, and strong underwater swimming.
Representative species: Emperor Penguin, Little Penguin, African Penguin, and Northern Rockhopper Penguin.
Conservation note: Threats vary by species and include food-web change, warming seas, fisheries interactions, disease, oil pollution, and disturbance at colonies.

39. Ostrich

Group of ostriches walking across open ground — The Common Ostrich and Somali Ostrich are the two living ostrich species.

Ostriches are the largest living birds and the only members of Struthionidae. The Common Ostrich (Struthio camelus) and Somali Ostrich (S. molybdophanes) are separate species. Both are flightless runners with long legs, two toes on each foot, and wings used for display, balance, and maneuvering.

Known for: Exceptional running speed, large eggs, powerful kicks, and open-country adaptations.
Habitat: Savannas, grasslands, shrublands, and semi-arid landscapes in Africa.
Diet: Mostly plants and seeds, supplemented with insects and other small animals.

40. Kiwi

Brown kiwi foraging on the ground — Kiwi are nocturnal, flightless birds found only in New Zealand.

Kiwi are five flightless species in the genus Apteryx, endemic to New Zealand. They have hair-like feathers, small hidden wings, strong legs, and nostrils near the tip of the bill. Smell, touch, and hearing help them locate worms, insects, and other food in leaf litter and soil.

Five species: Brown Kiwi, Great Spotted Kiwi, Little Spotted Kiwi, Rowi, and Tokoeka.
Population context: New Zealand’s Department of Conservation estimates about 70,000 kiwi remain, with status varying by species.
Main threats: Introduced predators, dogs, habitat change, vehicle strikes, and the vulnerability of small isolated populations.

Why bird conservation cannot be reduced to one status

A group such as “eagle,” “sparrow,” or “penguin” can contain species with very different population trends. BirdLife International’s 2025 global assessment reported 1,256 bird species as globally threatened and found that 61% of assessed species had declining populations. The most useful response is species-specific: protect the places a bird needs, reduce preventable mortality, and monitor whether management is working.

Across the birds in this guide, recurring pressures include habitat loss and degradation, invasive predators, unsustainable hunting or trade, pollution, fishing interactions, collisions, and climate-driven changes to food and breeding conditions. Learning about different ecosystem types helps explain why the same threat affects species in different ways.

A clearer way to think about bird diversity

The 40 names above are useful starting points, not equal taxonomic units. Some represent families, some combine unrelated lineages, and some describe sex or life stage. The most reliable way to understand a bird is to connect its common name with its scientific group, field marks, behavior, range, and species-level conservation status.
