It is the only species for which we know the exact date of extinction. In fact, the last known bird (a female named Martha) died at the Cincinnati Zoo in 1914 at the amazing age of 29 years.  This, and the fact that the related louse C. angustus is mainly found on cuckoo-doves, further supports the relation between these pigeons, as the phylogeny of lice broadly mirrors that of their hosts.  In the same edition, Linnaeus also named C. canadensis, based on Turtur canadensis, as used by Mathurin Jacques Brisson in 1760.  It has been suggested that the passenger pigeon should be revived when available technology allows it (a concept which has been termed "de-extinction"), using genetic material from such specimens. The passenger pigeon or wild pigeon (Ectopistes migratorius) is an extinct species of pigeon that was endemic to North America.  Even within their range, the size of individual flocks could vary greatly. After feeding, the pigeons perched on branches and digested the food stored in their crop overnight.  Due to these influences, some ecologists have considered the passenger pigeon a keystone species, with the disappearance of their vast flocks leaving a major gap in the ecosystem. Its common name is derived from the French word passager, meaning "passing by", due to the migratory habits of the species. To try to figure out what happened, scientists analyzed DNA … It has been suggested that the passenger pigeon could be used as a "flagship" species to spread awareness of other threatened, but less well-known North American birds.

This bowl was then typically lined with finer twigs. , The last recorded nest and egg in the wild were collected in 1895 near Minneapolis.  The passenger pigeon roosted in such numbers that even thick tree branches would break under the strain. 1492: Passenger Pigeon population likely numbers 3-5 billion birds, or roughly 40 percent of all avian life on the continent, as Columbus arrives. By Elizabeth PennisiNov. The Seneca developed a pigeon dance as a way of showing their gratitude.  The pigeon was considered so numerous that 30,000 birds had to be killed to claim the prize in one competition. However, the 2017 study's "conservative" estimate of an "effective population size" of 13 million birds is still only about 1/300th of the bird's estimated historic population of approximately 3–5 billion before their "19th century decline and eventual extinction. The bird had a small head and neck.  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. , Today, more than 1,532 passenger pigeon skins (along with 16 skeletons) are in existence, spread across many institutions all over the world. Furthermore, the parent pigeons that would raise the cloned passenger pigeons would belong to a different species, with a different way of rearing young. Some outside the camp agree with Shapiro’s interpretation, however.  Such a number would likely represent a large fraction of the entire population at the time, or perhaps all of it.  Unlike other pigeons, courtship took place on a branch or perch. As well as these "cities", there were regular reports of much smaller flocks or even individual pairs setting up a nesting site. It was duller than the male overall, and was a grayish-brown on the forehead, crown, and nape down to the scapulars, and the feathers on the sides of the neck had less iridescence than those of the male. , The American chestnut trees that provided much of the mast on which the passenger pigeon fed was itself almost driven to extinction by an imported Asian fungus (chestnut blight) around 1905. The body is elevated, the throat swells, the eyes sparkle. Birds in the back of the flock flew to the front in order to pick over unsearched ground; however, birds never ventured far from the flock and hurried back if they became isolated. At the beginning of the 19th century, biologists estimate that there were about 3 to 5 billion passenger pigeons living in their home range of deciduous forests around eastern North America, making it the most abundant bird on the continent, and perhaps in the world. 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. 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. Proc Natl Acad Sci USA. I looked out of my bedroom window, and as I looked six wild pigeons flew down and perched on the dead branches of a tall poplar tree that stood about one hundred feet away.  It originally bred from the southern parts of eastern and central Canada south to eastern Kansas, Oklahoma, Mississippi, and Georgia in the United States, but the primary breeding range was in southern Ontario and the Great Lakes states south through states north of the Appalachian Mountains. The neck feathers had no iridescence. The continental population may have been as high as 6 billion, a number that could represent anywhere from 25 to 40 percent of all the birds in North America 350 years ago. “This study suggests that the passenger pigeon’s most distinctive feature—its immense population size—left an enduring mark on its genome,” says Benjamin Van Doren, an evolutionary ecology graduate student at the University of Oxford in the United Kingdom not involved in the work. The primary and secondary feathers of the wing were a blackish-brown with a narrow white edge on the outer side of the secondaries. Like the domestic Pigeon and other species, they caress each other by billing, in which action, the bill of the one is introduced transversely into that of the other, and both parties alternately disgorge the contents of their crop by repeated efforts. It was equally as adept and quick at flying through a forest as through open space.  The study also found that the size of the passenger pigeon population over that time period had been larger than the 2014 genetic study had found. The nesting period lasted around four to six weeks. Project Passenger Pigeon’s leaders hope that by sharing the pigeon’s story, they can impress upon adults and children alike our critical role in environmental conservation.  The price of a barrel full of pigeons dropped to below fifty cents, due to overstocked markets. , The passenger pigeon differed from the species in the genus Zenaida in being larger, lacking a facial stripe, being sexually dimorphic, and having iridescent neck feathers and a smaller clutch. During her last four years in solitude (her cage was 5.4 by 6 m (18 by 20 ft)), Martha became steadily slower and more immobile; visitors would throw sand at her to make her move, and her cage was roped off in response. When landing, the pigeon flapped its wings repeatedly before raising them at the moment of landing. In contrast to the 2010 study, these authors suggested that their results could indicate that the ancestors of the passenger pigeon and its Old World relatives may have originated in the Neotropical region of the New World. " In the 18th and 19th centuries, various parts of the pigeon were thought to have medicinal properties. The most often reproduced of these illustrations was captioned "Winter sports in northern Louisiana: shooting wild pigeons", and published in 1875. The passenger pigeon clearly was adapted to large populations. The passenger pigeon clearly was adapted to large populations. This suggests that the net effect of Native-American activities on passenger-pigeon population size was neutral. And when a new threat—like human hunters and habitat loss—came around, they suddenly found their physiology and behavior were poorly suited for their declining numbers. The next step would be to splice these genes into the stem cells of rock pigeons (or band-tailed pigeons), which would then be transformed into egg and sperm cells, and placed into the eggs of rock pigeons, resulting in rock pigeons bearing passenger pigeon sperm and eggs.
