(Probably) Extinct subspecies of birds
Extinction of subspecies is a subject very dependent on guesswork. National and international conservation projects and research publications such as redlists usually focus on species as a whole. Reliable information on the status of threatened subspecies usually has to be assembled piecemeal from published observations such as regional checklists. Therefore, the following listing contains a high proportion of taxa that may just as well still exist, but are listed here due to any combination of absence of recent records, a known threat such as habitat destruction, or an observed decline.
The Ostrich and related ratites.
- Arabian Ostrich, Struthio camelus syriacus (Arabia,
1966) - Ostrich subspecies
Tasmanian Emu, Dromaius novaehollandiae diemenensis (Tasmania, mid-19th century) - Emu subspecies
North Island Little Spotted Kiwi, Apteryx owenii iredalei (North Island, New Zealand, late 19th century) - Little Spotted Kiwi subspecies
- Pernambuco Solitary Tinamou, Tinamus solitarius pernambucensis (E Brazil, c.1970s)
- A subspecies of the Solitary Tinamou which may not be valid but probably is.
- Huila Black Tinamou, Tinamus osgoodi hershkovitzi (Colombia, 1980s?)
- A Black Tinamou subspecies or possibly a distinct species; not seen since 1976 but might persist in Cueva de los Guácharos National Park.
- Bering Cackling Goose, Branta hutchinsii asiatica (Komandorskie and Kurile Islands, N Pacific, c.1914 or 1929)
- A subspecies of the Cackling Goose (formerly "Lesser Canada Geese") which is doubtfully distinct from the Aleutian one.
- Washington Island Gadwall, Anas strepera couesi (Teraina, Kiribati, late 19th century) - Gadwall subspecies. Controversial species, as many scientists think that it just might be a immature of the Common Gadwall Anas strepera strepera which was drifted to Teraina.
- Rennell Island Teal, Anas gibberifrons remissa (Rennell, Solomon Islands, c.1959)
- A subspecies of the Sunda Teal which disappeared due to predation on young birds by the introduced tilapia Oreochromis mossambicus.
- Niceforo's Pintail, Anas georgica niceforoi (Colombia, 1950s) - Yellow-billed Pintail subspecies
- Borrero's Cinnamon Teal, Anas cyanoptera borreroi (Colombia, late 20th century?)

Quails and relatives.
- Italian Grey Partridge, Perdix perdix italica (Italy, c.1990)
- A subspecies of the Grey Partridge whose validity has been questioned; the last purebred individuals disappeared during the late 1980s due to hybridization with introduced birds.
- Amik Gölü Black Francolin, Francolinus francolinus billypayni (S Turkey, possibly Lebanon, 1960s)
- A doubtfully distinct subspecies of the Black Francolin.
- Sicilian Black Francolin, Francolinus francolinus ssp. (Sicily, Mediterranean, c.1869)
- Another doubtfully distinct Black Francolin subspecies.
- Heath Hen, Tympanuchus cupido cupido, (New England, North America, 1932)

- A subspecies of the Helmeted Guineafowl. Reportedly still kept in captivity in Morocco in late 1990s. Possibly extinct by 1950, the 3 1970s records may refer to feral domestic hybrids.
- North Island Snipe, Coenocorypha aucklandica
barrierensis (North Island, New Zealand, 1870s) - New
Zealand Snipe subspecies
South Island Snipe, Coenocorypha aucklandica iredalei (South and Stewart Islands, New Zealand, 1964) - New Zealand Snipe subspecies
Tawitawi Small Buttonquail, Turnix sylvatica suluensis (Tawitawi, Philippines, mid-20th century) - Small Buttonquail subspecies
New Caledonia Painted Buttonquail, Turnix varia novaecaledoniae (New Caledonia, Melanesia, early 20th century)
- A subspecies of the Painted Buttonquail of somewhat unclear status, it is variously considered anything between a hybrid between introduced species to a full species. Plentiful subfossil bones indicate that it was indeed a good endemic form.
- Kiritimati Sandpiper, Prosobonia cancellata cancellata (Kiritimati, Kiribati, 19th century?)
- The doubtfully distinct nominate subspecies of the Tuamotu Sandpiper, sometimes considered a distinct species, but only known from a painting.
Rails and allies.
- Goldman's Yellow Rail, Coturnicops noveboracensis
goldmani (Mexico, late 1960s) - Yellow Rail subspecies
Macquarie Island Buff-banded Rail, Gallirallus philippensis macquariensis (Macquarie Islands, SW Pacific, 1880s) - Buff-banded Rail subspecies
Raoul Island Banded Rail, Gallirallus philippensis ssp. (Raoul, Kermadec Islands, SW Pacific, late 19th century?)
- Reports of the former occurrence of the species on Raoul seem plausible enough, but they may relate to vagrant individuals of another Buff-banded Rail subspecies.
- Peruvian Rail, Rallus semiplumbeus peruvianus (Peru, 20th century?)
- A subspecies of the Bogota Rail which is known from a single specimen collected in the 1880s. It may still be extant.
- Western Australian Lewin's Rail, Lewinia pectoralis cleleandi (SW Australia, late 1930s) - Lewin's Rail subspecies
- Flores Lewin's Rail, Lewinia pectoralis exsul (Flores, Indonesia, late 19th century?)
- A Lewin's Rail subspecies known only form 4 specimens. Not seen since 1959 despite attempts to find it, it is apparently extinct.
- Assumption White-throated Rail, Dryolimnas cuvieri abbotti (Assumption, Astove and Cosmoledo, Aldabra Islands, early 20th century) - White-throated Rail subspecies.
- Jamaican Uniform Crake, Amaurolimnas concolor concolor (Jamaica, West Indies, 1890) - Uniform Crake nominate subspecies
- Intact Rail, Gymnocrex plumbeiventris intactus (Melanesia, 20th century?)

- Bornean Baillon's Crake, Porzana pusilla mira (Borneo, 20th century?)
- A subspecies of Baillon's Crake known from a single 1912 specimen and not found since; may be extinct, but species is hard to find.
- Iwo Jima White-browed Crake, Porzana cinerea brevipes (Iwo Jima and Minami Iōjima, Ogasawara Islands, early 20th century).
- A subspecies of the White-browed Crake that is often considered synonymous with the nominate.
- Moroccan Bustard, Ardeotis arabs lynesi (Morocco, 1990s)
- A subspecies of the Arabian Bustard. Last observed in 1993 at Lac Merzouga/Lac Tamezguidat.
- Luzon Sarus Crane, Grus antigone luzonica (Luzon, Philippines, late 1960s)
- A subspecies of the Sarus Crane which is not always accepted as valid, probably mainly because the specimens have never been thoroughly studied since the subspecies' description.
Herons and related birds.
- Bonin Nankeen Night Heron, Nycticorax caledonicus
crassirostris (Nakoudo-jima and Chichi-jima, Ogasawara
Islands, c.1890) - Nankeen Night Heron subspecies
Principe Olive Ibis, Bostrychia olivacea rothschildi (Principe, Gulf of Guinea, 1900s) - Olive Ibis subspecies
Cormorants and related birds.
- Tasman Booby, Sula dactylatra tasmani fide van Tets et al., 1988 (Lord Howe and Norfolk Islands, SW Pacific, c.1790?)
- This is often regarded as a distinct species, but at best it is a subspecies of the Masked Booby. Probably identical to the extant Lord Howe Island population described as S. d. fullagari, which would in this case be named S. d. tasmani fide Holdaway & Anderson, 2001.
- Levant Darter, Anhinga rufa chantrei (Middle East, early 1990s?)
- A questionable subspecies of the African Darter (Anhinga melanogaster chantrei if all Old World darters are considered one species) which ultimately seems to have become a victim of war and habitat destruction in Iraq.

- Chestnut-bellied Sandgrouse subspecies, may have survived until early 1980s.
Pigeons, doves and dodos.

Lord Howe Metallic Pigeon, Columba vitiensis godmanae (Lord Howe Island, Southwest Pacific, 1853)- Metallic Pigeon subspecies
Tongan Metallic Pigeon, Columba vitiensis ssp. (Vava'u, Tonga, late 18th century?)
- This subspecies of the Metallic Pigeon is only known from a footnote in John Latham's "General History of Birds", and seems to have died out some time before 1800; possibly, the location is erroneous and the note really refers to the extant population of Fiji.
- Catanduanes Bleeding-heart, Gallicolumba luzonica rubiventris (Catanduanes, Philippines, late 20th century?)
- A subspecies of the Luzon Bleeding-heart known from a single specimen collected in 1971. It is either near extinction or already extinct.
- Basilan Bleeding-heart, Gallicolumba crinigera bartletti (Basilan, Philippines, mid-20th century?)
- A subspecies of the Mindanao Bleeding-heart, it was last reported in 1925 and given the massive habitat destruction is likely extinct.
- Vella Lavella Ground Dove, Gallicolumba jobiensis chalconota (Vella Lavella, Makira and Guadalcanal, Solomon Islands, late 20th century?)
- A subspecies of the White-bibbed Ground Dove or possibly a distinct species. Known from only 4 specimens, there are no recent records and the local population report it has disappeared.
- White-headed Polynesian Ground-dove, Gallicolumba erythroptera albicollis (Central Tuamotu Islands, 20th century)
- The Central Tuamotu subspecies of the Polynesian Ground-dove, often referred to as G. e. pectoralis, disappeared at an undetermined date, but might still exist on some unsurveyed atolls. The identity of Northern Tuamotu populations, possibly still extant, is undetermined.
- Ebon Purple-capped Fruit Dove, Ptilinopus porphyraceus marshallianus (Ebon, Marshall Islands?, late 19th century?)
- Known from a single specimen collected in 1859, it is not certain whether this bird actually occurred on Ebon. All that can be said is that this subspecies is no longer found anywhere.
- Mauke Fruit Dove, Ptilinopus rarotongensis "byronensis" (Mauke, Cook Islands, mid-/late 19th century)
- A subspecies of the Rarotonga Fruit Dove, known only from the description of a now-lost specimen. the prehistorically extinct population on Mangaia is likely to belong to another distinct subspecies too.
- Negros Grey-necked Imperial-pigeon, Ducula carola nigrorum (Negros and probably Siquijor, late 20th century) - Grey-necked Imperial Pigeon subspecies
- Norfolk Island Kererū, Hemiphaga novaeseelandiae spadicea (Norfolk Island, Southwest Pacific, mid-19th century)
- A subspecies of the Kererū or New Zealand Pigeon. Similar birds were reported from Lord Howe Island; these seem to represent another extinct subspecies but are undescribed to date.
- Raoul Island Kererū, Hemiphaga novaeseelandiae ssp. nov. (Raoul, Kermadec Islands, 19th century)
- Another undescribed subspecies (or possibly species) of the Kererū, known from bones and a brief report.
- Sangir Red and Blue Lory, Eos histrio histrio (Sangir Archipelago, Indonesia, c.1997)
- The nominate subspecies of the Red and Blue Lory was hybridized out of existence by escaped trade individuals of the subspecies talautensis, the last purebred individuals disappearing in the 1990s or even much earlier.
- Challenger's Lory, Eos histrio challengeri (Nenusa Islands, Talaud Archipelago, early 20th century?)
- A supposed subspecies of the Red and Blue Lory, but probably invalid.

c.1891) - Subantarctic Red-crowned Parakeet nominate
Lord Howe Island Red-fronted Parakeet, Cyanoramphus novaezelandiae subflavescens (Lord Howe Island, SW Pacific, c.1870) - Red-crowned Parakeet subspecies
Westerman's Eclectus Parrot, Eclectus roratus westermani (Indonesia, 20th century?)
- Known only from 16 captive birds specimens and last recorded in 1899, this enigmatic subspecies of the Eclectus Parrot is often considered an aviary hybrid. However, it may has well have occurred on islands at the northern or eastern end of the Banda Sea, becoming extinct some time in the 20th century - or might even still exist in a little-surveyed location.
- Réunion Parakeet, Psittacula eques eques (Réunion, Mascarenes, mid-18th century)
- Known only from a painting and descriptions; if it is accepted as valid, it would become the nominate subspecies of the Echo Parakeet, extant on Mauritius, which would then have to be called P. eques echo.
- Siquijor Colasisi, Loriculus philippensis siquijorensis (Siquijor, Philippines, 1990s)

- Crested Coua subspecies, known only from a single specimen taken in 1950
- Timor Pheasant Coucal, Centropus phasianinus mui (Timor, Indonesia, late 20th century?)
- A very distinctive Pheasant Coucal subspecies or possibly a distinct species which is mysteriously only known from one specimen.
- Assumption Island Coucal, Centropus toulou assumptionis (Assumption Island, Seychelles, c.1920s)
- A Madagascar Coucal subspecies often considered synonymous with the Aldabra form insularis, which has recolonized Assumption Island at a later date.
- Cabo San Lucas Groove-billed Ani, Crotophaga sulcirostris pallidula (Mexico, c.1940)
- A weakly differentiated and probably invalid subspecies of the Groove-billed Ani
- Bahía Rufous-vented Ground Cuckoo, Neomorphus geoffroyi maximiliani (E Brazil, mid-20th century) - Rufous-vented Ground Cuckoo subspecies
- Cape Verde Kite, Milvus milvus fasciicauda (Cape Verde Islands, E Atlantic, 2000)
- Considered either a subspecies of the Red Kite, a distinct species, the validity of this taxon has recently being questioned based on molecular analysis. However, hybridization and a confusing molecular phylogeny of Red Kite populations coupled with the distinct phenotype of the Cape Verde birds suggest that the taxonomic status of this form is far from resolved.
- Anjouan Island Sparrow Hawk, Accipiter francesii pusillus
- This subspecies of Frances' Goshawk from Ndzouani (Anjouan), Comoros, was last seen in 1978; given that few habitat remains, it is probably extinct.
- Car Nicobar Sparrowhawk, Accipiter butleri butleri (Car Nicobar, Nicobar Islands, 20th century?)

- Sulu Reddish Scops Owl, Otus rufescens burbidgei (Sulu, Philippines, mid-20th century)
- A subspecies of the Reddish Scops Owl. Known from a single questionable specimen and may not be valid.
- Virgin Islands Screech Owl, Otus nudipes newtoni

- Socorro Elf Owl, Micrathene whitneyi graysoni (Socorro, Revillagigedo Islands, c.1970)
- A subspecies of the Elf Owl; the last specimen was taken in 1932, but there apparently still was a large population in 1958.

- Peleng Masked Owl, Tyto rosenbergii pelengensis (Peleng, Banggai Islands, mid-20th century)
- Subspecies of Sulawesi Owl or separate species. Possibly extant, but only specimen known taken in 1938 and no further records.
- Samar Bay Owl, Phodilus badius riverae (Samar, Philippines, mid-20th century)
- Subspecies of Oriental Bay Owl or possibly distinct species. Taxonomy doubtful but only specimen lost in 1945 bombing raid so validity cannot be verified; no population exists on Samar today.
Nightjars and allies.
- New Caledonian White-throated Eared-Nightjar, Eurostopodus mystacalis exsul (New Caledonia, Melanesia, mid-20th century)
- This distinct subspecies of the White-throated Eared-Nightjar is possibly a separate species. It was found only once; due to its cryptic habits, it possibly still exists, but this is now considered unlikely.
- Alejandro Selkirk Firecrown, Sephanoides fernandensis leyboldi (Alejandro Selkirk Island, Juan Fernandez Islands, Southeast Pacific, 1908) - Juan Fernandez Firecrown subspecies
- Luzon Whitehead's Swiftlet, Collocalia whiteheadi whiteheadi (Luzon, Philippines, 20th century?)
- The nominate subspecies of Whitehead's Swiftlet is only known from four specimens collected at Mount Data in 1895 and from the lack of further records and the massive habitat destruction, it is usually considered extinct. Given the size of the island, it might still exist though.
Kingfishers and related birds.
- Sangihe Dwarf-kingfisher, Ceyx fallax sangirensis (Sangihe, Indonesia, 1998?)
- This subspecies of the Sulawesi Kingfisher was last seen in 1997 but not during a thorough survey one year later; it is either close to extinction or already extinct. Sometimes it is said to occur on Talaud Islands also, but this is erroneous.
- Rarotonga Kingfisher, Todiramphus cf. tuta (Rarotonga, Cook Islands, mid-1980s?)
- There exist reports of locals that kingfishers - probably a subspecies of the Chattering Kingfisher which is found on neighboring islands, but possibly vagrants from there - were found until around 1979, and there is a last record from 1984. Presently, no kingfishers are known to exist on Rarotonga.
- Mangareva Kingfisher, Todiramphus gambieri gambieri (Mangareva, Gambier Islands, late 19th century)
- Only known from a single 1844 specimen, the nominate subspecies of the Tuamotu Kingfisher was not found anymore when it was next searched for in 1922.
- Javan Blue-banded Kingfisher, Alcedo euryzona euryzona (Java, Indonesia, mid-20th century)
- The nominate subspecies of the Blue-banded Kingfischer; the last specimen was taken in 1937 and the last unconfirmed records are from the 1950s.

(Guadalcanal, Solomon Islands) - Little Kingfisher
Malaita Variable Kingfisher, Ceyx lepidus malaitae (Malaita, Solomon Islands) - Variable Kingfisher subspecies
Sakarha Pygmy Kingfisher, Ispidina madagascariensis dilutus (Southwest Madagascar, late 20th century?)

- Ticao Tarictic Hornbill, Penelopides panini ticaensis (Ticao, Philippines, 1970s)
- A subspecies of the Tarictic Hornbill of somewhat uncertain status - possibly a distinct species, possibly a color morph -; the last confirmed report was in 1971 and it became extinct shortly thereafter.
Woodpeckers and related birds.
- Guadalupe Flicker, Colaptes cafer rufipileus (Guadalupe, East Pacific, c.1910)
- A subspecies of the Red-shafted Flicker (or the Northern Flicker, as C. auratus rufipileus), it was last recorded in 1906 and not found anymore in 1911 and 1922. Recently, vagrant birds of a mainland subspecies have begun recolonizing the island as the habitat improves after the removal of feral goats.
- Javan Buff-rumped Woodpecker, Meiglyptes tristis tristis (Java, Indonesia, c.1920)
- The nominate subspecies of the Buff-rumped Woodpecker became rare during the 19th century due to destruction of habitat. The last confirmed record was in 1880, and it obviously became extinct in the early 20th century.
- Northern White-mantled Barbet, Capito hypoleucus hypoleucus (Colombia, mid-20th century)
- The nominate subspecies of the White-mantled Barbet has not been seen since the late 1940s and its habitat has been almost completely destroyed.

- A subspecies of the Scale-throated Earthcreeper, it is only known from 2 specimens taken in the early 1950s at Puno, Peru, and has never been found since. It might still exist, or have become extinct due to habitat destruction in the meantime.
- Northern Stripe-crowned Spinetail, Cranioleuca pyrrhophia rufipennis (N Bolivia, late 20th century?)
- A Stripe-crowned Spinetail subspecies known from a few specimens and not recorded since the 1950s; may be endangered or even extinct.
Formicariidae - Antpittas and antthrushes
- Northern Giant Antpitta, Grallaria gigantea lehmanni (Colombia, late 20th century?)
- A Giant Antpitta (or possibly Great Antpitta) subspecies apparently not recorded since the 1940s. Might still survive in Puracé National Park.
- Narińo Giant Antpitta, Grallaria gigantea hylodroma (Colombia, c.1990?)
- Another Giant Antpitta subspecies, or possibly a distinct species, probably last recorded in 1989, but not anymore some years later. might still persist in La Planada Nature Reserve, but searches were unsuccessful.

- Hiva Oa Monarch, Pomarea mendozae mendozae (Hiva Oa and Tahuata, Marquesas, late 1970s) - Marquesas Monarch nominate subspecies
- Manu'a Shrikebill, Clytorhynchus vitiensis powelli (Manu'a Islands, Samoa, 1990s?)
- Usually treated as a subspecies of the Fiji Shrikebill but probably a distinct species, the American Samoan population declined due to habitat destruction and may have become extinct following the cyclones Ofa and Val.
- Nendo Shrikebill, Clytorhynchus nigrogularis sanctaecrucis (Nendo, Santa Cruz Islands, mid-20th century?)
- A subspecies of the Black-throated Shrikebill or more probably a distinct species that was only once found, in 1927. Due to lack of research it is not known whether this bird still exists; it was not found during the single thorough survey in recent times and it can be presumed to be affected by habitat destruction and typhoons.
- Lord Howe Fantail, Rhipidura fuliginosa cervina (Lord Howe Island, Southwest Pacific, c.1925) - Grey Fantail subspecies

Callaeidae - New Zealand wattlebirds
- South Island Kōkako, Callaeas cinerea cinerea (South Island, New Zealand, 1960s?)

Cinclidae - Dippers
- Cyprus Dipper, Cinclus cinclus olympicus (Cyprus, Northeast Mediterranean, 1950s)
- A subspecies of the White-throated Dipper of questionable validity.
Ploceidae - Weavers
- Ruwet's Masked-Weaver, Ploceus reichardi ruweti (D.R. Congo, late 20th century?)
