![]() Threats to Passenger PigeonsĪpart from the predators such as foxes, wolves, weasels, and hawks, they were also threatened by humans. These birds rarely travel toward Mexico and Cuba. They spent entire summer in the Rocky Mountains and Canada all throughout North America.The normal traveling speed was 50 – 60 miles per hour.They ordinarily travel great distances in that they didn’t often return to the same place for years.The migration commonly came about in March and April. Passenger pigeon facts about its adaptability display that these species migrated only in winter season.Passenger Pigeon Where did Passenger Pigeons Live? These birds predominantly fed on chestnuts, seeds, worms, small insects, beechnuts, acorns, and berries. The chicks remained with their parents for at least 30 days.Both parents contributed towards the incubation process.The incubation (keeping the eggs warm) period lasts for 12 – 14 days.The nests were 1 foot in diameter and are normally made of twigs and sticks.They are one of the most common species in the world. miles), and the total number of individuals exist count to 136 million. In Wisconsin, these birds cover more than 850 sq. They built their nests in forests where food and water are abundant.Passenger Pigeon Passenger Pigeon Reproduction Facts Passenger pigeon felt comfortable in groups as compared to when they were alone.These species were highly sociable and they are normally found in large gatherings consist of hundreds of individuals.The length of their tail was about 23 – 23 cm (8 – 9 inches).These types of pigeons were greater as compared to the Mourning Dove.The males were 42 cm (16.5 inches) long, while the length of the females was about 38 cm (15 inches). The size is same to that of the Rock Pigeon."Evolving Attitudes." CQ Researcher 2 (January 24, 1992): 58 –60. "In Memory of Martha and Her Kind." Audubon 91 (September 1989): 52 –55. Norman, OK: University of Oklahoma Press, 1973. Passenger Pigeon: Its Natural History and Extinction. It is now on display at the National Museum of Natural History in Washington, D.C. The last individual passenger pigeon was a female named Martha, which died in the Cincinnati Zoo in 1914. ![]() Once the population was split into small, isolated remnants, however, natural predation also contributed to the species' rapid decline. At one time the sheer numbers of passenger pigeons in a flock was enough to discourage potential predators. The disruption of the population in the 1860s and 1870s had been so severe that breeding success was permanently reduced. The remaining small flocks of birds were so spread out and isolated that their numbers were too low to be maintained. Michigan provided their last stronghold, but that population became extinct inġ889. The demand was particularly high on the East Coast where forest clearing and hunting had already eradicated the species from the area.īy the 1880s commercial hunting of passenger pigeons was no longer profitable, because the population had been depleted to only several thousand birds. Once killed, many of the birds were packed in barrels and shipped to cities where they were sold in markets and restaurants. In 1878, near Petoskey, Michigan, a professional market hunter earned $60,000 by killing over three million passenger pigeons near their nesting grounds. A common practice of the day was to use the live pigeons as targets in shooting galleries. They were baited with alcohol-soaked grain or with captive pigeons set up as decoys, then trapped and shot. Young squabs were easy prey for hunters who knocked them from their nests or forced them out by setting fires below them. It was also in demand as food, largely due to the fact that nesting flocks were easily accessible. The passenger pigeon was considered an agricultural pest, thus providing ample reason to kill large numbers of the birds. The species became extinct within a span of 50 years, several factors having led to its rapid demise. The artist and naturalist John James Audubon once observed a flock over a three-day period and estimated the birds were flying overhead at a rate of 300 million per hour. Alexander Wilson, the father of American ornithology, noted a flock he estimated to contain two billion birds. In the mid-1800s passenger pigeons travelled in flocks of astounding numbers. The passenger pigeon ( Ectopistes migratorius ), perhaps the world's most abundant bird species at one time, became extinct due directly to human activity.
