By Elizabeth Pennisi Nov. 16, 2017 , 2:00 PM. [40], If the pigeon became alert, it would often stretch out its head and neck in line with its body and tail, then nod its head in a circular pattern. Furthermore, the parent pigeons that would raise the cloned passenger pigeons would belong to a different species, with a different way of rearing young. This composite description cited accounts of these birds in two pre-Linnean books. [162][164], Media related to Ectopistes migratorius at Wikimedia Commons One out of every four birds in North America was believed to have been a Passenger Pigeon. [137] The price of a barrel full of pigeons dropped to below fifty cents, due to overstocked markets. After European colonization, the passenger pigeon was hunted more intensively and with more sophisticated methods than the more sustainable methods practiced by the natives. [55], The last recorded nest and egg in the wild were collected in 1895 near Minneapolis. The last surviving Passenger Pigeon, named Martha, was a member of this [140] Public protests against trap-shooting erupted in the 1870s, as the birds were badly treated before and after such contests. They rested in a slumped position that hid their feet. In the case of the passenger pigeon, since it was very social, it is unlikely that enough birds could be created for revival to be successful, and it is unclear whether there is enough appropriate habitat left for its reintroduction. The last confirmed wild bird is thought to have been shot in 1901. Its common name is derived from the French word passager, meaning "passing by", due to the migratory habits of the species. I cannot describe to you the extreme beauty of their aerial evolutions, when a hawk chanced to press upon the rear of the flock. [22][23] While the pigeon was extant, the name passenger pigeon was used interchangeably with "wild pigeon". Specifically, the study found that between 13% and 69% of red oak seeds were too large for passenger pigeons to have swallowed, that only a “small proportion” of the seeds of black oaks and American chestnuts were too large for the birds to consume, and that all white oak seeds were sized within an edible range. [34] These large fluctuations in population may have been the result of a disrupted ecosystem and have consisted of outbreak populations much larger than those common in pre-European times. This was said to be used to attract the attention of another pigeon. [78] The female chose the nesting site by sitting on it and flicking its wings. [16], The cladogram below follows the 2012 DNA study showing the position of the passenger pigeon among its closest relatives:[16] The flocks ranged from only 1.0 m (3.3 ft) above the ground in windy conditions to as high as 400 m (1,300 ft). One of these was Mark Catesby's description of the passenger pigeon, which was published in his 1731 to 1743 work Natural History of Carolina, Florida and the Bahama Islands, which referred to this bird as Palumbus migratorius, and was accompanied by the earliest published illustration of the species. [22] In his 1831 Ornithological Biography, American naturalist and artist John James Audubon described a migration he observed in 1813 as follows: I dismounted, seated myself on an eminence, and began to mark with my pencil, making a dot for every flock that passed. [142], For many years, the last confirmed wild passenger pigeon was thought to have been shot near Sargents, Pike County, Ohio, on March 24, 1900, when a female bird was killed by a boy named Press Clay Southworth with a BB gun. [31], The passenger pigeon was sexually dimorphic in size and coloration. [110] Low-flying pigeons could be killed by throwing sticks or stones. Four billion passenger pigeons vanished. [131] In one case, 6 km2 (1,500 acres) of large trees were speedily cut down to get birds, and such methods were common. The pigeon’s fate may hold lessons for other animals under pressure from humans or other dangers, says A. Townsend Peterson, an evolutionary biologist at the University of Kansas in Lawrence who was not involved with the work. A very fast flyer, the passenger pigeon could reach a speed of 100 km/h (62 mph). These creatures were not the dinosaurs of the Jurassic period or Roman soldiers two millennia past, but the Passenger Pigeon. ", and was used to call either to its mate or towards other creatures it considered to be enemies. The primary and secondary feathers of the wing were a blackish-brown with a narrow white edge on the outer side of the secondaries. [52] Even within their range, the size of individual flocks could vary greatly. The naturalists Alexander Wilson and John James Audubon both witnessed large pigeon migrations first hand, and published detailed accounts wherein both attempted to deduce the total number of birds involved. [18][19] The passenger pigeon had no known subspecies. [93] The Ho-Chunk people considered the passenger pigeon to be the bird of the chief, as they were served whenever the chieftain gave a feast. [111] Another method of capture was to hunt at a nesting colony, particularly during the period of a few days after the adult pigeons abandoned their nestlings, but before the nestlings could fly.

"Keeho" was a soft cooing that, while followed by louder "keck" notes or scolding, was directed at the bird's mate. [55] The early colonists thought that large flights of pigeons would be followed by ill fortune or sickness. [67], For fifteen thousand years or more before the arrival of Europeans in the Americas, passenger pigeons and Native Americans coexisted in the forests of what would later become the eastern part of the continental United States. Passenger pigeon was North American species of pigeon that lived in deciduous forests during the mating season, and in the pine forests and swamps during the winter. These birds numbered in the billions, an estimated 3 to 5 billion passenger pigeons graced the skies in the mid-1800s. This sound was described as "kee-kee-kee-kee" or "tete! The bird seems to have been slowly pushed westwards after the arrival of Europeans, becoming scarce or absent in the east, though there were still millions of birds in the 1850s. [22][30], Two parasites have been recorded on passenger pigeons. The passenger pigeon or wild pigeon (Ectopistes migratorius) is an extinct species of pigeon that was endemic to North America. [22][80], Upon hatching, the nestling (or squab) was blind and sparsely covered with yellow, hairlike down. In 2003, the Pyrenean ibex (Capra pyrenaica pyrenaica, a subspecies of the Spanish ibex) was the first extinct animal to be cloned back to life; the clone lived for only seven minutes before dying of lung defects. [117][118] The flavor of the flesh of passenger pigeons varied depending on how they were prepared. As many as thirty billion trees are thought to have died as a result in the following decades, but this did not affect the passenger pigeon, which was already extinct in the wild at the time. The undertail coverts also had a few black spots. The English common name "passenger pigeon" derives from the French word passager, which means "to pass by" in a fleeting manner. The specimens came from throughout the bird’s range. Yet human exploitation drove this species to extinction over the course of a few decades. It was especially fond of salt, which it ingested either from brackish springs or salty soil. The passenger pigeon clearly was adapted to large populations. Beth Shapiro, a paleogenomicist at the University of California, Santa Cruz, and colleagues sequenced the complete genomes of two passenger pigeons, and analyzed the mitochondrial genomes—which reside in structures that power cells—of 41 individuals. It is almost impossible to imagine that the passenger pigeons’ population, which in the early 1800’s contained more individuals than all other North American birds combined, was reduced to just one individual, Martha, who died in captivity at the Cincinnati Zoo in 1914. [124] After being opened up to the railroads, the town of Plattsburgh, New York is estimated to have shipped 1.8 million pigeons to larger cities in 1851 alone at a price of 31 to 56 cents a dozen. It is believed that the pigeons used social cues to identify abundant sources of food, and a flock of pigeons that saw others feeding on the ground often joined them. [80] A whole colony was known to re-nest after a snowstorm forced them to abandon their original colony. In captivity, a passenger pigeon was capable of living at least 15 years; Martha, the last known living passenger pigeon, was at least 17 and possibly as old as 29 when she died. [151] In 1902, Whitman gave a female passenger pigeon to the zoo; this was possibly the individual later known as Martha, which would become the last living member of the species. [48], These flocks were frequently described as being so dense that they blackened the sky and as having no sign of subdivisions. Conservationists were ineffective in stopping the slaughter. [56][57] Some early accounts also suggest that the appearance of flocks in great numbers was an irregular occurrence. 1492: Passenger Pigeon population likely numbers 3-5 billion birds, or roughly 40 percent of all avian life on the continent, as Columbus arrives. [91] Genetic research may shed some light on this question. The authors found evidence of a faster rate of adaptive evolution and faster removal of harmful mutations in passenger pigeons compared to band-tailed pigeons, which are some of passenger pigeons' closest living relatives. One observer described the motion of such a flock in search of mast as having a rolling appearance, as birds in the back of the flock flew overhead to the front of the flock, dropping leaves and grass in flight. Roosts ranged in size and extent, from a few acres to 260 km2 (100 sq mi) or greater. The legs and feet were dull red, and the iris was brownish, and surrounded by a narrow carmine ring. [14] Most estimations of numbers were based on single migrating colonies, and it is unknown how many of these existed at a given time. [22][51] The pigeon had no site fidelity, often choosing to nest in a different location each year. The juvenile was similar to the female, but without iridescence. The blood was supposed to be good for eye disorders, the powdered stomach lining was used to treat dysentery, and the dung was used to treat a variety of ailments, including headaches, stomach pains, and lethargy. The study concluded that earlier suggestion that population instability contributed to the extinction of the species was invalid. The brown mutation is a result of a reduction in eumelanin, due to incomplete synthesis (oxidation) of this pigment. The passenger pigeon was once the most abundant bird in North America, with a population possibly up to five billion. The pigeon bathed in shallow water, and afterwards lay on each side in turn and raised the opposite wing to dry it. Because of this — along with the breaking of tree limbs under their collective weight and the great amount of mast they consumed — passenger pigeons are thought to have influenced both the structure of eastern forests and the composition of the species present there. Hawks of the genus Accipiter and falcons pursued and preyed upon pigeons in flight, which in turn executed complex aerial maneuvers to avoid them; Cooper's hawk was known as the "great pigeon hawk" due to its successes, and these hawks allegedly followed migrating passenger pigeons. [33] The wing of the male measured 196 to 215 mm (7.7 to 8.5 in), the tail 175 to 210 mm (6.9 to 8.3 in), the bill 15 to 18 mm (0.59 to 0.71 in), and the tarsus was 26 to 28 mm (1.0 to 1.1 in). A slow decline between about 1800 and 1870 was followed by a rapid decline between 1870 and 1890. It is the only species for which we know the exact date of extinction. These migrating flocks were typically in narrow columns that twisted and undulated, and they were reported as being in nearly every conceivable shape. Many eggs were laid by his pigeons, but few hatched, and many hatchlings died. It preferred to winter in large swamps, particularly those with alder trees; if swamps were not available, forested areas, particularly with pine trees, were favored roosting sites. John James Audubon rode the 55 miles from Henderson, Kentucky, to Louisville one day in autumn 1813, and through the whole long day, he rode under a sky darkened from horizon to horizon by a cloud of passenger pigeons. Drastic population fluctuations explain the rapid extinction of the passenger pigeon Chih-Ming Hunga,1, Pei-Jen L. Shanera,1, Robert M. Zinkb, Wei-Chung Liuc, Te-Chin Chud, Wen-San Huange,f,2, and Shou-Hsien Lia,2 aDepartment of Life Science and dDepartment of Computer Science and Information Engineering, National Taiwan Normal University, Taipei 116, Taiwan; The passenger pigeon was once the most abundant bird in the world, with a population size estimated at 3-5 billion in the 1800s; its abrupt extinction in 1914 raises the question of how such an abundant bird could have been driven to extinction in mere decades. Pigeon feather beds were so popular that for a time in Saint-Jérôme, Quebec, every dowry included a bed and pillows made of pigeon feathers. The bird was described as a "perfect scourge" by some farming communities, and hunters were employed to "wage warfare" on the birds to save grain, as shown in another newspaper illustration from 1867 captioned as "Shooting wild pigeons in Iowa". But “I am persuaded by [Shapiro’s] argument, given this in-depth analysis of massive data resources.”. In the 1960s populations of the dickcissel, a sparrow-like neotropical migrant, began crashing, and some ornithologists predicted its extinction by 2000. Incidentally, the last specimen of the extinct Carolina parakeet, named "Incus," died in Martha's cage in 1918; the stuffed remains of that bird are exhibited in the "Memorial Hut". [50] John James Audubon described the courtship of the passenger pigeon as follows: Thither the countless myriads resort, and prepare to fulfill one of the great laws of nature. 16, 2017 , 2:00 PM. Few offenders were prosecuted, mainly some poor trappers, but the large enterprises were not affected. When comparing the population history of the PAssenger Pigeon to changes in forests it becomes clear that not only was the Passenger Pigeon a superbly adaptable species, but it was the major ecosystem engineer of eastern N. American forests – this discovery reveals the true value of returning Passenger Pigeon flocks to eastern N.American forests, the details of are summarized here. Pigeon meat was commercialized as cheap food, resulting in hunting on a massive scale for many decades. As I gazed at them in delight, feeling as though old friends had come back, they quickly darted away and disappeared in the fog, the last I ever saw of any of these birds in this vicinity. By 1855 passenger pigeons were still the most abundant bird in North America. Martha was on display for many years, but after a period in the museum vaults, she was put back on display at the Smithsonian's National Museum of Natural History in 2015. A flock was also adept at following the lead of the pigeon in front of it, and flocks swerved together to avoid a predator. Nests were built between 2.0 and 20.1 m (6.6 and 65.9 ft) above the ground, though typically above 4.0 m (13.1 ft), and were made of 70 to 110 twigs woven together to create a loose, shallow bowl through which the egg could easily be seen. [44] They regularly flew 100 to 130 km (62 to 81 mi) away from their roost daily in search of food, and some pigeons reportedly traveled as far as 160 km (99 mi), leaving the roosting area early and returning at night. [40] One of the primary causes of natural mortality was the weather, and every spring many individuals froze to death after migrating north too early. [160] Speaking on May 11, 1947, Leopold remarked: Men still live who, in their youth, remember pigeons. [67] The passenger pigeon sexually matured during its first year and bred the following spring. In these almost solid masses, they darted forward in undulating and angular lines, descended and swept close over the earth with inconceivable velocity, mounted perpendicularly so as to resemble a vast column, and, when high, were seen wheeling and twisting within their continued lines, which then resembled the coils of a gigantic serpent... Before sunset I reached Louisville, distant from Hardensburgh fifty-five miles. [94], French explorer Jacques Cartier was the first European to report on passenger pigeons, during his voyage in 1534. The decimation of the passenger pigeon population started in earnest when hunting them for sale as meat became an industry. DNA samples are often taken from the toe pads of bird skins in museums, as this can be done without causing significant damage to valuable specimens. This was proven inaccurate in 1999 when C. extinctus was rediscovered living on band-tailed pigeons. When the last passenger pigeon died at a zoo in 1914, the species became a cautionary tale of the dramatic impact humans can have on the world. The surviving adults attempted a second nesting at new sites, but were killed by professional hunters before they had a chance to raise any young. [32] There were also records of stragglers in Scotland, Ireland, and France, although these birds may have been escaped captives, or the records incorrect. [22][45] It took advantage of cultivated grains, particularly buckwheat, when it found them. Robert W. Shufeldt found little to differentiate the bird's osteology from that of other pigeons when examining a male skeleton in 1914, but Julian P. Hume noted several distinct features in a more detailed 2015 description. The extinction of this abundant bird in a mere five decades is a poignant reminder that even a bird numbering in the billions can be driven to extinction within a human lifetime ( 8 , 12 , 13 ). The normally black spots are brown, and it is pale gray on the head, lower back, and upper-tail covert feathers, yet the iridescence is unaffected. Nearly every tree capable of supporting nests had them, often more than 50 per tree; one hemlock was recorded as holding 317 nests. The Passenger Pigeon’s population then went into free fall, picking up dizzying speed on its inexorable downward spiral, until it finally crashed. Brisson's description was later shown to have been based on a female passenger pigeon. In the early 19th century, commercial hunters began netting and shooting the birds to sell as food in city markets, and even as pig fodder.

The time spent at one roosting site may have depended on the extent of human persecution, weather conditions, or other, unknown factors. Passenger Pigeon. [54] Such a number would likely represent a large fraction of the entire population at the time, or perhaps all of it. [107] Native Americans ate pigeons, and tribes near nesting colonies would sometimes move to live closer to them and eat the juveniles, killing them at night with long poles. [10] Its closest living relatives were long thought to be the Zenaida doves, based on morphological grounds, particularly the physically similar mourning dove (now Z. [148] A memorial statue of Martha stands on the grounds of the Cincinnati Zoo, in front of the "Passenger Pigeon Memorial Hut", formerly the aviary wherein Martha lived, now a National Historic Landmark. Scientists have long blamed hunting and deforestation for the passenger pigeon’s disappearance—the birds destroyed the very trees in which they nested—but biologists still couldn’t make sense of why they declined so quickly and completely. The combined effects of intense hunting and deforestation has been referred to as a "Blitzkrieg" against the passenger pigeon, and it has been labeled one of the greatest and most senseless human-induced extinctions in history. 1, 2020. [36] The rapid decline of the passenger pigeon has influenced later assessment methods of the extinction risk of endangered animal populations. How could the passenger pigeon be extinct when it was the most abundant bird species on Earth no so long ago? In contrast, very small populations of nearly extinct birds, such as the kakapo (Strigops habroptilus) and the takahe (Porphyrio hochstetteri), have been enough to keep those species extant to the present. [99] The centennial of its extinction was used by the "Project Passenger Pigeon" outreach group to spread awareness about human-induced extinction, and to recognize its relevance in the 21st century. The sheer number of juveniles on the ground meant that only a small percentage of them were killed; predator satiation may therefore be one of the reasons for the extremely social habits and communal breeding of the species. [14], The passenger pigeon wintered from Arkansas, Tennessee, and North Carolina south to Texas, the Gulf Coast, and northern Florida, though flocks occasionally wintered as far north as southern Pennsylvania and Connecticut. The male assumes a pompous demeanor, and follows the female, whether on the ground or on the branches, with spread tail and drooping wings, which it rubs against the part over which it is moving.

[123] In 1871, a single seller of ammunition provided three tons of powder and 16 tons (32,000 lb) of shot during a nesting. What's unclear is what the minimum viable population size would be for the species. [22][33], The tail pattern was distinctive as it had white outer edges with blackish spots that were prominently displayed in flight. The pigeon migrated in enormous flocks, constantly searching for food, shelter, and breeding grounds, and was once the most abundant bird in North America, numbering around 3 billion, and possibly up to 5 billion. [67] The egg was incubated by both parents for 12 to 14 days, with the male incubating it from midmorning to midafternoon and the female incubating it for the rest of the time.
