The time of the spring migration depended on weather conditions. During feeding, some individuals would give alarm calls when facing a threat, and the rest of the flock would join the sound while taking off. The last known individual of the passenger pigeon species was "Martha" (named after Martha Washington). The two central tail feathers were brownish gray, and the rest were white. However, this did not seem to seriously diminish the total number of birds. , The passenger pigeon was one of the most social of all land birds.  At least one trapper used alcohol-soaked grain as bait to intoxicate the birds and make them easier to kill. , The colonies, which were known as "cities", were immense, ranging from 49 ha (120 acres) to thousands of hectares in size, and were often long and narrow in shape (L-shaped), with a few areas untouched for unknown reasons. 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 pigeon could eat and digest 100 g (3.5 oz) of acorns per day.  A whole colony was known to re-nest after a snowstorm forced them to abandon their original colony. The one valuable result of the extinction of the passenger pigeon was that it aroused public interest in the need for strong conservation laws.  Another louse, Campanulotes defectus, was thought to have been unique to the passenger pigeon, but is now believed to have been a case of a contaminated specimen, as the species is considered to be the still-extant Campanulotes flavus of Australia. In general, juveniles were thought to taste the best, followed by birds fattened in captivity and birds caught in September and October. 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. tete!  The entire nesting cycle lasted about 30 days. For instance, while the passenger pigeon was extant, forests were dominated by white oaks. Naturalist Aldo Leopold paid tribute to the vanished species in a monument dedication held by the Wisconsin Society for Ornithology at Wyalusing State Park, Wisconsin, which had been one of the species' social roost sites. The Passenger Pigeon also known as Ectopistes migratorius is an extinct bird which was endemic to North America. It mainly inhabited the deciduous forests of eastern North America and was also recorded elsewhere, but bred primarily around the Great Lakes.  The wings had more spotting than those of the male. Authorities differ as to how many times the passenger pigeon nested in a season. The brown mutation is a result of a reduction in eumelanin, due to incomplete synthesis (oxidation) of this pigment. The nests were loosely constructed of small sticks and twigs and were about a foot in diameter. , In 1827 William John Swainson moved the passenger pigeon from the genus Columba to the new monotypic genus Ectopistes, due in part to the length of the wings and the wedge shape of the tail. There were several other factors contributing to the decline and subsequent extinction of the species, including shrinking of the large breeding populations necessary for preservation of the species and widespread deforestation, which destroyed its habitat. The bird's fat was stored, often in large quantities, and used as butter. , The passenger pigeon was a member of the pigeon and dove family, Columbidae.  When their interests clashed with the interests of man, civilization prevailed. 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. They also found evidence of lower genetic diversity in regions of the passenger pigeon genome that have lower rates of genetic recombination. It is thought this individual was named Martha because her last cage mate was named George, thereby honoring George Washington and his wife Martha, though it has also been claimed she was named after the mother of a zookeeper's friends. The wings were very long and pointed, and measured 220 mm (8.7 in) from the wing-chord to the primary feathers, and 120 mm (4.7 in) to the secondaries.  In 1952 Francis Hemming proposed that the International Commission on Zoological Nomenclature (ICZN) secure the specific name macroura for the mourning dove, and the name migratorius for the passenger pigeon, since this was the intended use by the authors on whose work Linnaeus had based his description.  The normal clutch size appears to have been a single egg, but there is some uncertainty about this, as two have also been reported from the same nests. It is unclear if the birds favored particular trees and terrain, but they were possibly not restricted to one type, as long as their nu… The coracoid bone (which connects the scapula, furcula, and sternum) was large relative to the size of the bird, 33.4 mm (1.31 in), with straighter shafts and more robust articular ends than in other pigeons. See a 360 Degree View of Martha, the Last Passenger Pigeon. Deforestation was driven by the need to free land for agriculture and expanding towns, but also due to the demand for lumber and fuel.  Natural selection can reduce genetic diversity over extended regions of a genome through 'selective sweeps' or 'background selection'. The colors of the female were duller and paler. The undertail coverts also had a few black spots. Roosts ranged in size and extent, from a few acres to 260 km2 (100 sq mi) or greater.  Despite the number of predators, nesting colonies were so large that they were estimated to have a 90% success rate if not disturbed. Most early accounts dwell on the vast number of pigeons, the resulting darkened skies, and the enormous amount of hunted birds (50,000 birds were reportedly sold at a Boston market in 1771). Both parents shared the duties of incubating the egg and feeding the young. The last captive birds were divided in three groups around the turn of the 20th century, some of which were photographed alive. The International Union for the Conservation of Nature (IUCN) has used the passenger pigeon as an example in cases where a species was declared "at risk" for extinction even though population numbers are high.. Other sources argue that Martha was hatched at the Cincinnati Zoo, had lived there for 25 years, and was the descendant of three pairs of passenger pigeons purchased by the zoo in 1877.
