Birds that contain O

List of Birds That Contain O

1

Albatross

Diomedea exulans

The largest flying bird by wingspan, a Southern Ocean seabird that can glide thousands of kilometers without flapping and live over 60 years.

2

Avocet

Recurvirostra avosetta

Britain's most elegant wader — a black-and-white bird with an extraordinary upturned bill that it swings from side to side through shallow water to catch invertebrates; the symbol of the RSPB, the avocet returned to breed in Suffolk in 1947 after an absence of over 100 years and is now one of British conservation's greatest success stories.

3

Booby

Sula nebouxii

A large, torpedo-shaped seabird that hunts by plunge-diving from heights of 30 metres — remarkable for its sky-blue or bright red feet used in elaborate courtship displays, and for colonial nesting on remote islands.

4

Cockatoo

Cacatuidae (family)

A loud, intelligent Australasian parrot with a distinctive crest of feathers — including the most affectionate parrot species and some of the most ecologically destructive flocks, with several species critically endangered.

5

Condor

Gymnogyps californianus (California); Vultur gryphus (Andean)

Two massive vulture species — the California condor (rescued from near-extinction in 1987 with only 27 birds remaining) and the Andean condor (the world's largest flying bird by combined wingspan and weight).

6

Cormorant

Phalacrocoracidae (family)

A diving water bird with non-waterproof feathers — visible drying with spread wings on rocks and pilings, used for centuries by Asian fishermen as living fishing tools, and now ecologically critical fish-eaters across coastal and inland waters worldwide.

7

Corn Bunting

Emberiza calandra

The largest British bunting — a large, streaky, plain-brown bird of arable fields with no distinctive markings but an utterly unmistakable song, often described as jangling keys; the corn bunting has declined severely across Britain as intensive farming reduced the cereal stubble, rough grassland, and insect-rich field margins on which it depends; polygamous males may mate with up to 18 females in a season.

8

Crossbill

Loxia curvirostra

A finch with a uniquely crossed bill — the upper and lower mandibles overlap like a pair of scissors, allowing it to prise open pine and spruce cones and extract the seeds inside with precision; crossbills can breed in the depths of winter when cones are ripe, sometimes nesting in snow.

9

Crow

Corvus brachyrhynchos

A large, all-black corvid widespread across North America — among the most intelligent of all birds, with sophisticated tool use, problem-solving, and individual face recognition.

10

Cuckoo

Cuculus canorus (common cuckoo)

A medium-sized bird famous for its distinctive call (the basis of cuckoo clocks) and brood parasitism — laying eggs in other species' nests to be raised by unwitting foster parents.

11

Dove

Columba livia (rock dove); also Streptopelia, Zenaida, others

A small to medium-sized bird of the pigeon family — peace symbol across cultures, the white morph used in religious imagery, and the common name shared with the genus including the rock pigeon of every city worldwide.

12

Falcon

Falco peregrinus (peregrine falcon)

A swift, sharp-winged raptor — including the peregrine, the fastest animal on Earth — with extraordinary diving speeds and a long history as a hunting partner in royal falconry traditions.

13

Flamingo

Phoenicopterus roseus

A long-legged wading bird whose pink color comes from carotenoid pigments in its food, famous for filter-feeding upside-down and standing on one leg.

14

Goldcrest

Regulus regulus

Britain's smallest bird — the goldcrest weighs as little as a 10-pence coin, and at 4–7 g is the joint-smallest bird in Europe alongside the firecrest; a tiny olive-green bird with a bright stripe on the crown — yellow in females, orange-red in males, displayed when excited; common in coniferous woodland and one of the most abundant British birds despite suffering severe losses in cold winters.

15

Goldfinch

Carduelis carduelis

A brilliantly coloured small finch with a crimson face, black and white head, and gleaming yellow wingbars — a specialist seed-eater that uses its narrow bill to extract seeds from thistles and teasels; one of Britain's most beloved garden birds.

16

Goose

Branta canadensis

A large migratory waterfowl with a black neck and white chinstrap, abundant across North America and increasingly resident in suburban parks where milder winters and grass lawns allow year-round survival.

17

Grouse

Tetraonidae (subfamily, sometimes treated as family)

A family of plump ground-dwelling birds adapted to cold climates — including iconic species like ruffed grouse, sage grouse, and ptarmigan, with elaborate dramatic mating displays in many species.

18

Guillemot

Uria aalge

A sea-going auk that nests by the million on vertical sea cliffs, packing shoulder-to-shoulder in dense colonies — it flies underwater using its wings to pursue fish to depths of 180 metres, and its pear-shaped egg rolls in a circle rather than off the cliff edge if knocked.

19

Heron

Ardea herodias (great blue heron)

A long-legged wading bird that stands motionless in shallow water, then strikes with neck-spear precision — the great blue heron a familiar sight at North American wetlands.

20

Hobby

Falco subbuteo

A dashing, long-winged falcon — sleek and swift, with the silhouette of a large swift, the hobby is one of Britain's most aerial predators, specialising in catching dragonflies and swallows in flight at speed; adults have slate-grey upperparts, heavily streaked underparts, and vivid rusty-red thighs and undertail; a summer visitor from Africa, arriving in late spring when dragonflies emerge.

21

Hoopoe

Upupa epops

A cinnamon-orange bird with a dramatic black-tipped crown that fans open into a bold crest — found across Africa, Europe, and Asia, the national bird of Israel, and known in many cultures as a messenger between the worlds.

22

Hornbill

Bucerotidae (family; 55 species)

A large tropical bird defined by its enormous brightly colored bill topped with a casque — a forest frugivore and icon of African and Asian biodiversity, and the subject of one of the most unusual nesting behaviors in the bird world.

23

House Martin

Delichon urbicum

A familiar summer visitor that builds its distinctive mud nest under the eaves of houses — arriving from southern Africa each April, house martins construct domed cup nests from hundreds of individual pellets of mud gathered from puddle edges; the white rump is the key identification feature separating it from the swallow.

24

Junco

Junco hyemalis

A small, ground-foraging sparrow nicknamed the "snowbird," common in winter across North America with regional color forms so different they were once classified as separate species.

25

Little Owl

Athene noctua

Britain's smallest owl and the only one to be diurnal — this compact, flat-headed owl perches in the open on fence posts, telegraph poles, and old walls, staring at passers-by with intense yellow eyes and bobbing its head in indignation; introduced to Britain from the Continent in the 1870s and 1880s, it is now a naturalised and widely distributed species.

26

Loon

Gavia immer

A primitive-looking diving bird of northern lakes with a haunting yodeling call, awkward on land but exceptional underwater — the official bird of Ontario and a symbol of northern wilderness.

27

Mockingbird

Mimus polyglottos (Northern); various other Mimus and Mimidae species

A medium-sized gray songbird famous for mimicking dozens of other species — capable of imitating 200+ songs and sounds across a lifetime, with the northern mockingbird as Harper Lee's literary symbol of innocence.

28

Oriole

Icterus galbula (Baltimore); other Icterus species

A vivid orange-and-black North American songbird with elaborate woven hanging nests — closely related to blackbirds, with multiple species across the Americas including the iconic Baltimore oriole that gave the city's baseball team its name.

29

Ostrich

Struthio camelus

The world's largest living bird — flightless, two-toed, capable of running at 70 km/h, laying the largest eggs of any bird, and producing meat increasingly farmed across the globe.

30

Owl

Tyto alba

A heart-faced, ghostly nocturnal raptor found on every continent except Antarctica, and one of the most efficient rodent-controllers in the natural world.

31

Oystercatcher

Haematopus ostralegus

A boldly pied coastal wader with a long, bright orange bill used as a hammer and lever to open bivalves — conspicuous, loud, and one of the most recognisable shorebirds of rocky coastlines worldwide.

32

Parrot

Psittacus erithacus

A medium-sized grey parrot widely regarded as the most cognitively gifted bird species, capable of imitating human speech and demonstrating reasoning beyond simple mimicry.

33

Peacock

Pavo cristatus

A large pheasant native to South Asia whose male sports a vivid iridescent train and elaborate fan display, the textbook example of sexual selection in evolution.

34

Pigeon

Columba livia

A globally ubiquitous urban bird descended from the rock dove of Mediterranean cliffs — domesticated for over 5,000 years for food, communication, racing, and ornamentation, with feral populations in nearly every city worldwide.

35

Plover

Charadrius and Pluvialis spp.

A family of compact, fast-running shorebirds found on beaches, mudflats, and grasslands worldwide — famous for the killdeer's broken-wing distraction display that lures predators away from the nest.

36

Razorbill

Alca torda

A cliff-nesting seabird with a distinctive laterally flattened "razor" bill, banded in white — the closest living relative of the extinct great auk; it dives deep for fish by flying underwater with its wings, nests on cliff ledges in large colonies alongside guillemots and puffins, and is an excellent indicator of North Atlantic fish stocks.

37

Ring Ouzel

Turdus torquatus

The mountain blackbird of Britain's uplands — a stocky thrush resembling a blackbird with a distinctive white crescent bib, breeding on moorland and mountain slopes above 250 metres; a migratory species that arrives from Africa in late March and departs by October, its far-carrying, melancholy song one of the definitive sounds of the wild uplands.

38

Roadrunner

Geococcyx californianus (greater roadrunner)

A long-legged ground cuckoo of southwestern North America that runs fast rather than flies — eats lizards, snakes (including rattlesnakes), and forms the basis for the Looney Tunes character chasing Wile E. Coyote.

39

Robin

Turdus migratorius

A large, orange-breasted thrush common across North American lawns and gardens, an early sign of spring and the most numerous land bird on the continent.

40

Roller

Coracias garrulus

A brilliant blue and chestnut European and African bird named for its spectacular rolling display flight — one of the most colourful birds of open Mediterranean and African habitats.

41

Sparrow

Passer domesticus (house sparrow); various Passerellidae species

A small, brown, ubiquitous songbird — the house sparrow following human settlements globally, the native New World sparrows often confused with it, all unfussy about food and habitat.

42

Spoonbill

Platalea leucorodia

A tall, all-white wading bird with a spatula-shaped bill that sweeps side to side through shallow water — one of Europe's most spectacular wetland birds, and a conservation success story after near-extinction in northwestern Europe.

43

Stonechat

Saxicola rubicola

A compact, upright chat of heathland and coastal scrub — the male has a striking black head, white collar, and bright orange breast, and sits prominently on gorse or bramble stems making a harsh "wheet-tsak-tsak" call like two pebbles being knocked together; year-round resident on British heathland, it is one of the first birds to establish territories in January.

44

Stork

Ciconiidae (family)

A large long-legged wading bird famous in folklore for delivering babies — about 19 species worldwide ranging from the white stork's chimney-top nests to the marabou's massive 3 m wingspan.

45

Swallow

Hirundo rustica (barn swallow); Hirundinidae family

A graceful, fast-flying songbird that catches insects on the wing — the barn swallow nesting in human structures across the Northern Hemisphere, performing transcontinental migrations.

46

Toucan

Ramphastos toco

The largest toucan species, a Central and South American fruit-eater with a striking oversized orange bill that serves as a thermal radiator as well as a feeding tool.

47

Vireo

Vireonidae (family)

Small olive-green songbirds of American forests known for persistent singing — especially the red-eyed vireo, which holds the record for most songs sung in a day at over 22,000 individual songs.

48

Whitethroat

Sylvia communis

A scratchy, energetic warbler of bramble scrub and overgrown hedgerows — the male has a white throat that puffs out during his jerky song-flight display, in which he rises a few metres into the air and parachutes back down singing; a common summer visitor that suffered a catastrophic population crash in 1969 due to Sahel drought.

49

Willow Tit

Poecile montanus

Britain's most rapidly declining resident bird — the willow tit has lost over 90% of its British population since the 1970s, one of the steepest declines of any British species; virtually identical to the marsh tit but distinguishable by its duller black cap, pale wing panel, and very different nasal buzzing call; it excavates its own nest hole in rotten wood, an unusual behaviour for a tit.

50

Woodcock

Scolopax rusticola

The forest phantom of the twilight — the woodcock is almost never seen by day, relying on extraordinary cryptic plumage of dead-leaf brown, chestnut, and black bars to become invisible on the woodland floor; it emerges at dawn and dusk to probe soft ground for earthworms with its long, sensitive bill; males perform a distinctive display flight called roding over woodland in the breeding season.

51

Woodpecker

Dryocopus pileatus

A large, crow-sized woodpecker with a vivid red crest, the model for Woody Woodpecker; chisels rectangular holes deep into wood with a series of head-snapping impacts.

52

Yellowhammer

Emberiza citrinella

A bright yellow European bunting whose distinctive song is often transcribed as "a little bit of bread and no cheeeese" — a familiar farmland bird in the British Isles, declining with the loss of mixed agriculture.
