Open any bird identification guide and the letter G delivers an unusual mix: a duck that steals food from coots, a cockatoo famous for acting like a fool, and a falcon built for Arctic winters. The G section of the alphabet also covers some of the most geographically scattered birds on the planet, from Angolan rainforest endemics to Galapagos seabirds found nowhere else on Earth.
This ornithology reference walks through 37 bird names that start with G, grouped loosely by family so related species sit near each other. Much like a list of birds starting with letter A moves from the familiar American Robin to the obscure Aplomado Falcon, this G-list moves between backyard regulars and birds most Americans will only ever see in a field guide.
1. Gadwall
The Gadwall (Mareca strepera) is a dabbling duck often overlooked next to flashier waterfowl. In a world where male ducks sport gleaming patches of green, red, or blue, the Gadwall’s understated elegance can make this common duck easy to overlook, with males intricately patterned in gray, brown, and black while females resemble female Mallards but with a thinner, darker bill. According to Cornell Lab’s All About Birds, Gadwall sometimes steal food from American Coots and from other ducks.
Numbers have been trending upward for decades. Gadwall have increased in numbers since the 1980s, partly because of conservation of wetlands and adjacent uplands in their breeding habitat through the Conservation Reserve Program and the North American Waterfowl Management Plan. Females are prolific layers during nesting season — a typical clutch runs 7-12 eggs with an incubation period of 24-27 days, according to the same Cornell Lab life history profile.
2. Galah
Few Australian birds carry a name as loaded with meaning as the Galah (Eolophus roseicapilla). Its pink face and breast paired with pale grey wings make it unmistakable, and it ranks among the continent’s most recognizable parrots. The Nature Australia conservation program notes that Australia’s commonest and most widespread cockatoo is the Galah.
The bird’s reputation runs deeper than plumage. The humorous antics of these iconic Australian cockatoos led to their name being applied to anyone acting the fool, and Galahs do indeed sometimes seem to be just having fun, like taking turns to slide down cables and wires. Per Wikipedia’s entry on the species, the galah readily hybridizes with several species, including the sulphur-crested cockatoo, little corella, Major Mitchell’s cockatoo, and cockatiel.
Galahs are also popular aviary birds. The Lafeber pet bird resource reports that in conservation status designation, they are considered to be of “least concern.” In the wild they tolerate harsh inland conditions better than most parrots their size, foraging across arid grassland and farmland alike.
3. Gallinule
Gallinules belong to the rail family, Rallidae, a group of secretive marsh birds known for long toes that spread their weight across floating vegetation. Most gallinule species share a similar body plan: chicken-sized, laterally compressed for slipping through reeds, and topped with a brightly colored facial shield. They swim with a distinctive head-bobbing motion rather than the smooth glide of ducks.
Two gallinule species appear regularly across the United States and Latin America, each covered individually below. Both nest among dense marsh vegetation and raise chicks that can swim and forage within hours of hatching, an adaptation shared with many rail relatives.
4. Purple Gallinule
The Purple Gallinule (Porphyrio martinica) is arguably the most colorful marsh bird in North America. Its body shows deep purple-blue feathering that shifts to iridescent green on the back, paired with a bright red-and-yellow bill and a pale blue forehead shield. Long yellow legs and oversized toes let it walk across lily pads without sinking.
This species favors freshwater marshes across the southeastern United States, Central America, and much of South America. Unlike many wading birds, Purple Gallinules will climb into shrubs and low trees to forage, using their long toes almost like hands to grip stems while reaching for fruit and seeds.
5. Common Gallinule
The Common Gallinule (Gallinula galeata) looks plainer than its purple cousin but is just as distinctive up close. Slate-gray body feathers contrast with a bright red frontal shield and matching red bill tipped in yellow. Birders scanning for identifying field marks often note the species’ reddish eyes, which stand out against the dark plumage.
Common Gallinules nest in cattail marshes and slow-moving freshwater ponds throughout much of the Americas. They are vocal birds, producing a range of clucks and whinnying calls that often give away their presence before they’re spotted swimming along a pond’s reedy edge.
6. Gannet
The Northern Gannet (Morus bassanus) is a large seabird built for high-speed plunge-diving. Adults are mostly white with black wingtips and a pale golden wash on the head, and they nest in dense, noisy colonies on coastal cliffs around the North Atlantic. When hunting, a gannet can fold its wings and drop from considerable height, hitting the water at speeds fast enough to stun small fish before they can react.
Breeding colonies can hold tens of thousands of pairs packed onto narrow cliff ledges, each pair defending just enough space to avoid pecking range from its neighbors. Gannets mate for life and perform an elaborate bill-fencing greeting ritual whenever a partner returns to the nest site.
7. Galapagos Penguin
The Galapagos Penguin (Spheniscus mendiculus) holds a geographic record among its family: it is the only penguin species found north of the equator, thanks to the cool, nutrient-rich Cromwell Current that flows through the islands. Standing barely over a foot tall, it is also one of the smallest penguin species anywhere.
Because it lives in the tropics rather than polar seas, this penguin has adapted unusual heat-coping behaviors, including panting, holding its flippers away from its body, and seeking shade during the hottest hours. Its population is considered vulnerable, closely tied to the health of the Galapagos marine ecosystem and fluctuations linked to El Niño events.
8. Galapagos Hawk
The Galapagos Hawk (Buteo galapagoensis) sits at the top of the islands’ food chain, filling a role similar to eagles or large owls elsewhere. Dark brown overall with a hint of rufous in the tail, it preys on everything from lava lizards and young iguanas to insects and carrion left behind by larger animals.
One of the species’ more unusual traits is cooperative polyandry: a single female may mate with and raise young alongside several male partners at once, an uncommon breeding system among raptors. Having evolved with few natural predators, Galapagos Hawks show little fear of humans, often allowing close observation.
9. Galapagos Petrel
The Galapagos Petrel (Pterodroma phaeopygia) is a seabird that spends most of its life far offshore, only returning to land to breed in burrows dug into the highland soils of a handful of Galapagos islands. Dark gray-brown above and white below, it is built for gliding long distances over open ocean on stiff, narrow wings.
This species faces real conservation pressure. Introduced predators such as rats, cats, and pigs raid ground nests, while habitat loss from agriculture on the inhabited islands has shrunk available nesting ground. Conservation groups now manage predator control programs around key breeding colonies to protect remaining nesting sites.
10. Gabar Goshawk
The Gabar Goshawk (Micronisus gabar) is a small, agile African raptor found across savanna and dry woodland south of the Sahara. Most individuals are gray above with a barred gray-and-white chest, though a less common all-black color morph also occurs in some populations. Adults show bright red eyes, bare red facial skin, and red legs that stand out against the gray plumage.
This goshawk hunts small birds and reptiles, often ambushing prey from a concealed perch rather than chasing in open flight. It will also raid the nests of weaver birds, sometimes taking over an entire colonial nest structure for its own breeding use.
11. Gabela Bushshrike
The Gabela Bushshrike (Laniarius amboimensis) ranks among the more obscure entries on any list of birds with unusual or little-known names, and for good reason: it is restricted to a small patch of montane forest near Gabela, Angola. Olive-green above with a yellow belly, it skulks low in dense undergrowth, making sightings genuinely rare even for dedicated birders who travel specifically to find it.
Habitat loss from agricultural clearing has pushed this species onto conservation watch lists. Its entire known range covers only a few forest fragments, which makes the Gabela Bushshrike one of the most range-restricted birds whose name starts with G.
12. Gabela Akalat
The Gabela Akalat (Sheppardia gabela) shares the same tiny Angolan forest range as the bushshrike above and faces similarly steep conservation challenges. This small, rust-and-olive robin-like bird forages on the forest floor and in low shrubs, feeding mainly on insects and small invertebrates turned up in leaf litter.
Like many Angolan forest endemics, the Gabela Akalat suffered from decades of civil conflict that limited research access to its habitat. Recent surveys suggest the population remains small and fragmented, and ongoing deforestation continues to threaten the handful of forest patches it depends on.
13. Gambel’s Quail
Gambel’s Quail (Callipepla gambelii) is an unmistakable desert bird, sporting a comical black top-knot plume that curves forward over its forehead. Males show a bold black face patch outlined in white, a rufous cap, and a scaled gray-and-chestnut body pattern that provides effective camouflage against desert rock and scrub.
This species thrives across the arid Southwest, often seen running in tight family groups called coveys rather than flying when disturbed. Readers curious about other members of the quail family, including birds whose names start with Q, will find Gambel’s Quail sits alongside several close relatives adapted to similarly dry habitats.
14. Goldfinch
The American Goldfinch (Spinus tristis) is a familiar backyard visitor across much of the United States, instantly recognizable in summer when males turn brilliant lemon-yellow with a black cap and wings. Winter brings a drab olive plumage that often confuses casual birdwatchers unfamiliar with the seasonal molt.
Goldfinches are strict vegetarians among North American songbirds, feeding almost entirely on seeds even when raising chicks, an unusual diet choice compared to most insect-feeding songbird relatives. Gardeners hoping to attract them should check which backyard plants are safe, since some common ornamentals fall on lists of plants that are poisonous to birds.
15. Goldcrest
The Goldcrest (Regulus regulus) is one of Europe’s smallest birds, weighing barely more than a modern coin. Olive-green overall with a bold yellow-and-black crown stripe, it moves through conifer canopies at a near-constant flicker, gleaning tiny insects and spider eggs from needle clusters.
Despite its tiny size, the Goldcrest tolerates remarkably cold winters across northern and central Europe, relying on a high metabolism and near-constant feeding to survive long nights. Some populations undertake surprising migratory journeys across open sea, a feat that seems improbable given the bird’s small stature.
16. Golden-Cheeked Warbler
The Golden-cheeked Warbler (Setophaga chrysoparia) breeds exclusively in central Texas, making it one of the few bird species with a breeding range confined entirely within a single U.S. state. Males show a striking black-and-yellow face pattern with a black throat and back, contrasting sharply against white underparts.
This warbler depends on mature Ashe juniper trees, stripping bark specifically from older trees to build its nest. Because suitable juniper-oak woodland has shrunk due to development and land clearing, the species is federally listed and remains a conservation priority for Texas Hill Country land managers.
17. Golden Eagle
The Golden Eagle (Aquila chrysaetos) is one of the largest and most powerful raptors in North America, with a wingspan that can stretch beyond six feet. Dark brown overall, adults show a golden-brown wash across the back of the head and neck that gives the species its name.
Golden Eagles hunt rabbits, ground squirrels, and other small to medium mammals, often working mountainous terrain and open grassland where they can spot prey from considerable altitude. Pairs frequently reuse the same massive stick nest for years, adding new material each breeding season until some nests reach enormous size.
18. Goliath Heron
The Goliath Heron (Ardea goliath) earns its name honestly: it is the largest heron species in the world, standing nearly five feet tall with a correspondingly massive dagger-like bill. Chestnut-colored head and neck contrast with slate-gray wings and back, making this African wetland bird unmistakable even at a distance.
Despite its size, the Goliath Heron hunts with the same patient, motionless stance used by smaller herons, waiting for fish to swim within striking range before stabbing downward. Birders who enjoy wading-bird identification might also appreciate exploring bird names that start with I, since several ibis species share similar wetland habitat with the Goliath Heron across African river systems.
19. Goose
Geese occupy a middle ground between ducks and swans within the waterfowl family, generally larger than dabbling ducks but more terrestrial in their feeding habits, often grazing on grass in open fields rather than staying strictly on water. Most species form strong pair bonds that can last a lifetime, and many undertake long seasonal migrations in the familiar V-formation flight pattern.
Several goose species show striking white wing plumage, most notably the Snow Goose, which breeds in the high Arctic and winters in huge flocks across the central and southern United States. Family groups tend to stay together through the first migration, with young geese learning flight routes directly from their parents.
20. Greylag Goose
The Greylag Goose (Anser anser) holds a special place in ornithological history as the ancestor of most domestic goose breeds raised today. Wild birds are gray-brown overall with a stout pink or orange bill, and they breed across much of northern Europe and Asia before migrating south for winter.
This species became famous through the imprinting research of ethologist Konrad Lorenz, whose studies on Greylag goslings following the first moving object they saw after hatching helped establish the modern field of animal behavior science. Wild populations remain widespread and stable across much of their European range.
21. Gull
Gulls, placed in the family Laridae, include dozens of species ranging from small, tern-like forms to large, heavy-bodied scavengers common along coastlines and inland waterways alike. Most species show a similar basic pattern: white or gray body plumage, darker wings, and a stout bill adapted for an opportunistic diet of fish, invertebrates, and scavenged food.
Many gull species develop distinctive red bill markings during the breeding season, a feature chicks instinctively peck at to trigger a feeding response from parents, a behavior studied extensively in classic animal behavior research. Gulls are highly adaptable, thriving equally well around fishing harbors, landfills, and urban parking lots far from any coastline.
22. Grouse
Grouse belong to the pheasant family and are built for life on the ground, with feathered legs and feet that provide insulation in cold climates where many species live. Most grouse rely on camouflage rather than flight to avoid predators, flushing explosively into short, powerful bursts of flight only when a threat gets close.
Courtship displays rank among the most elaborate in the bird world, with many grouse species gathering at communal display grounds called leks, where males perform synchronized dances, inflate colorful air sacs, or drum their wings to attract females. These rituals have made grouse a favorite subject for wildlife documentary footage for decades.
23. Grackle
The Common Grackle (Quiscalus quiscula) is a large, glossy blackbird found across much of the eastern and central United States. In good light, its black plumage reveals iridescent purple, blue, and bronze tones across the head and body, a quality easy to miss when the bird is seen only in silhouette.
Grackles are highly adaptable omnivores, feeding on insects, grain, small fish, and even the eggs or nestlings of other birds when the opportunity arises. Large winter roosts can number in the thousands, and their loud, creaky calls often announce a flock’s presence well before it comes into view.
24. Greenfinch
The European Greenfinch (Chloris chloris) is a stocky finch with olive-green plumage brightened by yellow flashes on the wings and tail. Its thick, pale bill is built for cracking seeds, and the species readily visits garden feeders stocked with sunflower hearts across much of Europe.
Greenfinch populations experienced significant declines in parts of the United Kingdom following outbreaks of trichomonosis, a parasitic disease spread at communal feeding stations. Conservation groups now recommend regular feeder cleaning as a simple way backyard birders can help limit disease transmission among finches and other feeder visitors.
25. Great Hornbill
The Great Hornbill (Buceros bicornis) is one of Asia’s most striking forest birds, dominated by a massive yellow-and-black casque sitting atop an already oversized bill. This casque is largely hollow, made of lightweight keratin rather than solid bone, but it still contributes to one of the most recognizable silhouettes in the hornbill family.
Breeding pairs display an extraordinary nesting strategy: the female seals herself inside a tree cavity using mud and droppings, leaving only a narrow slit through which the male passes food for weeks. Birders fascinated by unusual bill coloration might also enjoy browsing birds with orange beaks, since the hornbill’s casque often carries a similar warm orange-yellow wash depending on age and diet.
26. Great Horned Owl
The Great Horned Owl (Bubo virginianus) is among the most widespread and powerful owls in the Americas, instantly recognized by its prominent ear tufts and deep, resonant hooting call. Mottled brown-and-gray plumage provides effective camouflage against tree bark, while enormous, forward-facing eyes give it exceptional night vision for hunting.
These owls take an unusually broad range of prey for a raptor, including skunks, which most predators avoid entirely. Anyone interested in the adaptations behind that striking stare should take a look at birds with notably large eyes, a trait that defines most nocturnal owl species.
27. Green Woodpecker
The Green Woodpecker (Picus viridis) stands apart from most woodpeckers in its feeding habits, spending more time foraging on the ground than hammering tree trunks. Olive-green body plumage, a bright red crown, and a distinctive laughing call, often described as “yaffling,” make this species easy to identify across its European range.
Ants form the bulk of this woodpecker’s diet, and its unusually long, sticky tongue allows it to probe deep into anthills for prey. Lawns and open parkland riddled with small excavated holes are often a sign that a Green Woodpecker has been hunting for ants nearby.
28. Greater Flamingo
The Greater Flamingo (Phoenicopterus roseus) is the largest and most widespread flamingo species, found across parts of Africa, southern Europe, and Asia. Its pale pink body plumage intensifies with age and diet, while orange-red wing coverts become visible in flight, framed by contrasting black flight feathers.
That rosy coloration comes directly from pigments called carotenoids found in the algae and small crustaceans these birds filter-feed from shallow, saline lakes. Greater Flamingos nest in massive colonies on mudflats, building cone-shaped mud nests that help keep eggs safe from flooding.
29. Great Egret
The Great Egret (Ardea alba) is a tall, elegant white heron found on wetlands across nearly every continent except Antarctica. During breeding season, adults grow long, delicate plumes called aigrettes along the back, feathers that were once so prized by the millinery trade that hunting nearly drove the species to collapse in North America.
That near-extinction crisis helped launch the modern conservation movement in the United States, directly inspiring the formation of the National Audubon Society in the late 1800s. Today Great Egret populations have recovered substantially and the species remains a common sight along marshes, rivers, and coastal shallows.
30. Grey Heron
The Grey Heron (Ardea cinerea) is the Eurasian counterpart to North America’s Great Blue Heron, sharing a similar tall, patient hunting style along riverbanks and lake margins. Pale gray body plumage contrasts with a white head marked by a bold black stripe extending back from the eye into a short crest.
This heron is remarkably adaptable, nesting in large colonies called heronries built high in trees, sometimes far from the water where adults actually hunt. Grey Herons will take almost any prey small enough to swallow, including fish, amphibians, small mammals, and even the occasional small bird.
31. Greater Prairie-Chicken
The Greater Prairie-Chicken (Tympanuchus cupido) is a grassland grouse famous for its booming courtship display, performed each spring at traditional lek sites across the American Midwest. Males inflate bright orange air sacs on the neck while stamping their feet and raising specialized neck feathers called pinnae, producing a low, resonant booming sound audible from considerable distance.
Historic grassland loss across the Great Plains has sharply reduced this species’ range, and some subspecies, including the Attwater’s Prairie-Chicken, now survive only through intensive captive breeding and reintroduction programs. Readers who enjoy tracking grassland and prairie species might also explore bird names that start with K, several of which share similar open-country habitat preferences.
32. Gyrfalcon
The Gyrfalcon (Falco rusticolus) is the largest falcon species in the world, built for hunting across open Arctic tundra where few trees exist for cover. Plumage varies dramatically by region, ranging from nearly pure white morphs in the high Arctic to dark gray and even near-black forms found farther south.
This falcon relies on raw speed and power rather than the near-vertical stoop used by its smaller relative, the Peregrine Falcon, often pursuing prey such as ptarmigan in extended, low-level chases across open ground. Falconers have prized Gyrfalcons for centuries, and historically only royalty were permitted to fly them in medieval Europe.
33. Glistening-Green Tanager
The Glistening-green Tanager (Chlorochrysa phoenicotis) is a small, vividly colored songbird found in humid cloud forests of Colombia and Ecuador. As its name suggests, iridescent emerald-green plumage covers most of the body, set off by a contrasting black mask and a warm chestnut patch on the ear coverts.
This tanager typically forages in mixed-species flocks moving through the forest canopy, a common strategy among Andean tanagers that improves foraging efficiency and predator detection. Fruit makes up a large portion of its diet, supplemented with insects gleaned from leaves and moss-covered branches.
34. Glittering-Bellied Emerald
The Glittering-bellied Emerald (Chlorostilbon lucidus) is a small hummingbird widespread across much of central and southern South America. Males show brilliant emerald-green throat and underparts that flash with iridescence depending on the angle of light, a feature typical of many emerald hummingbird species.
Like most hummingbirds, this species maintains an extremely high metabolism, feeding on nectar from a wide variety of flowering plants throughout the day to sustain near-constant flight. It readily adapts to gardens and parks, making it one of the more commonly observed hummingbirds across urban areas of its range.
35. Green-Backed Firecrown
The Green-backed Firecrown (Sephaniodes sephaniodes) is a hummingbird native to Chile and Argentina, notable for being one of the southernmost hummingbird species in the world. Males display a brilliant coppery-red crown that can appear nearly fluorescent in direct sunlight, contrasting against iridescent green upperparts.
This species tolerates cooler temperatures better than most hummingbirds, surviving in temperate forest habitats far from the tropics typically associated with the family. During particularly cold nights, Green-backed Firecrowns can enter torpor, a temporary state of reduced metabolism that conserves energy until temperatures rise again.
36. Green-Backed Flycatcher
The Green-backed Flycatcher (Ficedula elisae) is a small East Asian songbird that breeds in forested areas of northern China before migrating south to spend winters in Southeast Asia. Olive-green upperparts and a yellow throat and breast distinguish it from several closely related flycatcher species with overlapping ranges.
This species was only formally separated from the similar Narcissus Flycatcher in recent decades, following closer study of plumage and vocal differences between populations. Its secretive forest habits and relatively recent taxonomic recognition mean comparatively little is documented about its detailed breeding behavior compared to more extensively studied flycatchers.
37. Green-Backed Gerygone
The Green-backed Gerygone (Gerygone chloronota) is a small Australasian warbler found across northern Australia, New Guinea, and nearby islands. Olive-green upperparts and pale underparts give it a subtle, understated appearance compared to many of the more colorful species covered on any bird names that start with Z list, yet its song carries a delicate, descending quality that stands out in the forest canopy.
This gerygone builds a distinctive domed, hanging nest with a side entrance, often suspended from a thin branch or vine. Insects make up the bulk of its diet, gleaned actively from leaves and twigs as the bird moves restlessly through mid-canopy foliage.
Thirty-seven species, six continents, and almost every habitat type imaginable: that is the range covered by bird names that start with G. Some, like the Gadwall and Greylag Goose, turn up on ponds across entire continents, while others, like the Gabela Bushshrike and Gabela Akalat, survive in forest patches small enough to walk across in an afternoon. For birders building out a personal checklist, the letter G rewards patience with real diversity, and pairs naturally with other alphabet guides, including birds that start with X, for anyone working through the full A-to-Z of bird identification.
