List of North American animals extinct in the Holocene

From Wikipedia, the free encyclopedia

Map of North America

This is a list of North American animals extinct in the Holocene that covers extinctions from the Holocene epoch, a geologic epoch that began about 11,650 years before present (about 9700 BCE)[A] and continues to the present day.[1]

Recently extinct animals in the West Indies and Hawaii are in their own respective lists.

Many extinction dates are unknown due to a lack of relevant information.

Common name Scientific name Range Comments Pictures
California grizzly bear Population of the grizzly bear (Ursus arctos horribilis) California Last recorded at Sequoia National Park in 1924.[32] Though once named as the subspecies U. a. californicus, DNA evidence shows that it is not different enough to warrant separate status.[33]

[edit]
Common name Scientific name Range Comments Pictures
Mexican horse Equus conversidens Western North America A small non-caballine species that coexisted in North America with the caballine horse (E. ferus).[40] The most recent remains were dated to 8965-8875 BCE.[4]
Locally extinct
[edit]
Common name Scientific name Range Comments Pictures
Wild horse Equus ferus Eurasia and North America Environmental DNA last detected in permafrost of central Yukon dated to 3979-2640 BCE.[41] The Yukon population has been identified at times as a different species of caballine horse (Equus lambei) and a wild ass (both Equus hemionus and Equus africanus) on morphological grounds, but ancient mtDNA studies confirms caballine affiliation.[40] Domestic horses were introduced to the Americas by the Spanish in 1493 and a feral population was established in Querétaro, Mexico by 1553.[42]

Atlantic gray whale Population of the gray whale (Eschrichtius robustus) North Atlantic Ocean and Mediterranean Sea Last recorded in 1760. The same species survives on the Pacific Ocean.[43] A single individual, presumably dispersed over the Arctic, was observed off Florida in 2023 and Nantucket, Massachusetts in 2024.[44]

Common name Scientific name Range Comments Pictures
Stag-moose Cervalces scotti Great Lakes Region Most recent remains dated to 9230-8930 BCE.[4]
Eastern elk Population of the North American wapiti (Cervus canadensis canadensis) Eastern North America Traditionally considered the nominate subspecies, but genetic research indicates that there are not enough differences to consider separate subspecies of C. canadensis in North America, and the taxon C. c. canadensis is not extinct as a result.[45][46] The last confirmed individual was killed near the Clarion River of central Pennsylvania in 1867, though there were unconfirmed sightings in 1869-1870, and ten claimed killings in northern Pennsylvania in 1878. Western elk were reintroduced for hunting purposes in the same state in 1912.[47]
Merriam's elk Population of the North American wapiti (Cervus canadensis canadensis) New Mexico, Arizona, and West Texas Named as the species Cervus merriami in 1902 on the basis of a single skull; in 1978, an anatomical review of a dozen individuals found just enough of a case to consider it a subspecies of Cervus elaphus (later C. canadensis). Further anatomical and genetic research suggest that all American wapiti likely belong to the same subspecies and that the taxon C. c. merriami is a synonym of C. c. canadensis. Wapiti from other regions have been reintroduced to the purported distribution area of Merriam's elk.[46]
Queen Charlotte Islands caribou Population of the caribou (Rangifer tarandus) Graham Island, British Columbia Described as the subspecies R. t. dawsoni in 1900 due to its isolated location and anatomical differences, but mtDNA studies in 2002 showed not enough differences to warrant separate status.[48] The last known herd was found in 1908, comprising two adult males, one female, and one calf; all but the calf were killed.[49]

[edit]

Pigeons and doves (family Columbidae)

[edit]
Common name Scientific name Range Comments Pictures
Passenger pigeon Ectopistes migratorius Eastern North America One of the most numerous birds at the beginning of the 19th century, it declined dramatically as a result of hunting, Newcastle disease, and the clearance of hardwood trees in which it fed, until the last individual in the wild was shot in 1900.

Extinct in the wild
[edit]
Common name Scientific name Range Comments Pictures

[edit]
Common name Scientific name Range Comments Pictures
Eskimo curlew Numenius borealis Americas Last confirmed record in Nebraska in 1987; an unconfirmed sighting happened in Manitoba in 1996. Declined due to hunting, conversion of prairies for agriculture, and the suppression of the fire regime. The breeding grounds in the Arctic have since been taken over by the larger Hudsonian whimbrel.[62] Another factor may have been the extinction of the Rocky Mountain locust.[63]

Northern storm petrels (family Hydrobatidae)

[edit]
Possibly extinct
[edit]
Common name Scientific name Range Comments Pictures
Guadalupe storm-petrel Hydrobates macrodactylus Guadalupe Island, Mexico Last recorded in 1912. Likely extinct due to breeding habitat degradation by introduced feral goats and predation by feral cats and dogs; however the natural difficulty of its detection, lack of thorough surveys in the breeding season after 1906 and reports of unidentified storm-petrel calls at night may indicate that it is still extant.[65]

Common name Scientific name Range Comments Pictures
Painted vulture Sarcoramphus sacra Florida Hypothetical species known from a 1774 description by William Bartram. Though traditionally dismissed as a hoax or incorrect description of a king vulture from Central and South America (S. papa), which it resembled in everything except the tail's coloration and more predatory behavior, a 1734 account of the same bird and painting by Eleazar Albin, and a 1786 depiction of the tail feathers as part of a standard used by the Muscogee king Mico Chlucco suggest that it was an actual extirpated Floridan population of the king vulture, subspecies, or related species.[66]

Dusky seaside sparrow Ammospiza maritima nigrescens Merritt Island and Titusville, Florida Declined due to DDT use in marshes and habitat loss caused by dam construction. In 1981 the last five individuals, all male, were captured and taken into captivity.[56] However, a proposed plan to hybridize them with Scott's seaside sparrow and select the offspring with most dusky ancestry wasn't allowed because of legal restrictions against hybridizing endangered taxa.[74] The last individual died in Walt Disney World's Discovery Island Zoological Park in Orlando, Florida in 1987.[56]

  1. ^ The source gives "11,700 calendar yr b2k (before CE 2000)". But "BP" means "before CE 1950". Therefore, the Holocene began 11,650 BP. Doing the math, that is c. 9700 BCE.
