Drastic population fluctuations explain the rapid extinction of the passenger pigeon

Drastic population fluctuations explain the rapid extinction of the passenger pigeon

The number of passenger pigeons went from billions to zero in mere decades, in contrast to conventional wisdom that enormous population size provides a buffer against extinction. Our understanding of the passenger pigeon’s extinction, however, has been limited by a lack of knowledge of its long-term population history. Here we use both genomic and ecological analyses to show that the passenger pigeon was not always super abundant, but experienced dramatic population fluctuations, which could increase its vulnerability to human exploitation. Our study demonstrates that high-throughput–based ancient DNA analyses combined with ecological niche modeling can provide evidence allowing us to assess factors that led to the surprisingly rapid demise of the passenger pigeon.

To assess the role of human disturbances in species’ extinction requires an understanding of the species population history before human impact. 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. Although human exploitation is often blamed, the role of natural population dynamics in the passenger pigeon’s extinction remains unexplored. Applying high-throughput sequencing technologies to obtain sequences from most of the genome, we calculated that the passenger pigeon’s effective population size throughout the last million years was persistently about 1/10,000 of the 1800’s estimated number of individuals, a ratio 1,000-times lower than typically found. This result suggests that the passenger pigeon was not always super abundant but experienced dramatic population fluctuations, resembling those of an “outbreak” species. Ecological niche models supported inference of drastic changes in the extent of its breeding range over the last glacial–interglacial cycle. An estimate of acorn-based carrying capacity during the past 21,000 y showed great year-to-year variations. Based on our results, we hypothesize that ecological conditions that dramatically reduced population size under natural conditions could have interacted with human exploitation in causing the passenger pigeon’s rapid demise. Our study illustrates that even species as abundant as the passenger pigeon can be vulnerable to human threats if they are subject to dramatic population fluctuations, and provides a new perspective on the greatest human-caused extinction in recorded history.

Red-billed pigeon

Red-billed pigeon

The Red-billed Pigeon, Patagioenas flavirostris , is a relatively large pigeon which breeds from southern Texas, United States, and northwestern Mexico south to Costa Rica. It belongs to a clade of Patagioenas which generally lack iridescent display plumage, except some vestiges in the Pale-vented Pigeon.

The Red-billed pigeon is classified as Least Concern. Does not qualify for a more at risk category. Widespread and abundant taxa are included in this category.

The Red-billed Pigeon, Patagioenas flavirostris (see Johnson et al. 2001), is a relatively large pigeon which breeds from southern Texas, United States, and northwestern Mexico south to Costa Rica. It belongs to a clade of Patagioenas which generally lack iridescent display plumage, except some vestiges in the Pale-vented Pigeon. It is found in open country with some trees, large clearings and cultivation in lowlands and middle altitudes to 2100 meters.

The Red-billed Pigeon has a large range, estimated globally at 830,000 square kilometers. Native to the United States and Mexico as well as Belize, Costa Rica, El Salvador, Guatemala, Honduras, and Nicaragua, this bird prefers neritic, oceanic, and coastal marine ecosystems. The global population of this bird is estimated at 500,000 to 5,000,000 individuals and does not show signs of decline that would necessitate inclusion on the IUCN Red List.

Meet the hero carrier pigeon that saved US troops during a WWI battle 100 years ago

Meet the hero carrier pigeon that saved US troops during a WWI battle 100 years ago

In the third floor hallway of the Pentagon, just outside the Army Chief of Staff’s office, there is a pigeon.

That pigeon’s name is “President Wilson” — an unsung hero of World War I that made a daring flight to save U.S. troops exactly 100 years ago on Friday.

President Wilson was a military carrier pigeon, one of many in the U.S. Army Signal Corps that delivered messages between commanders and troops on the front lines. The pigeons were especially useful tools of communication during World War I when the telephone and telegraph were still unreliable new technologies.

According to U.S. military accounts recorded in the U.S. Army Center of Military History and the National Archives, Wilson was born in France and first assigned to the U.S. Army’s newly formed Tank Corps, delivering messages to Tank Battalions commanded by Col. George S. Patton in the Battle of Saint-Mihiel.

But soon afterward, Wilson was assigned to an infantry unit conducting operations near Grandpré during the Meuse-Argonne Offensive.

On the morning of Oct. 5, 1918, his unit came under attack, and Wilson was dispatched to send a message that the unit needed artillery support. During the 25-mile journey, German soldiers spotted him and began firing into his flight path. (It should be noted that some accounts of Wilson’s heroics place the event as occurring on Nov. 5, but multiple historians reached by ABC corroborated the Oct. 5 date.)

Wilson was hit several times, losing a leg and suffering a wound to his chest, but he managed to deliver the message in a record 25 minutes.

Surviving his wounds, Wilson was retired and sent to the U.S. Army Signal Corps Breeding and Training Center at Fort Monmouth, New Jersey, where he would live another eleven years.

After his death, Wilson was taxidermied and presented to the Smithsonian Institution before being transferred to the custody of the U.S. Army in 2008. Now, located in the prestigious halls of the U.S. military’s headquarters in Arlington, Virginia, Wilson serves as a reminder that these simple birds — often considered a nuisance by the general public — were once war heroes.

Carrier pigeons were used by both the Allied and Central Powers during World War I and could even provide updates to military commanders when launched in midair from planes.

“Launched mid-mission, the birds would fly back to their coops and update ground commanders on what the pilots had observed,” the National Archives wrote in a blog post in January. “Quick updates like this were essential for leaders to know what the battlefield looked like and what the enemy was doing in its own trenches.”

“Tanks carried the birds in order to relay the advance of individual units. Even after the introduction of the radio, pigeons were often the easiest way to help coordinate tank units without exposing the men to dangerous fire. Without a radio set, the soldiers would have had to leave the relative safety of their tanks to relay or receive orders,” the Archives said.

When the pigeons weren’t in use, they were stored in mobile units, often converted horse carriages or even double-decker buses.

The birds are thought to use low-frequency sound waves to map their environments and find their way from location to location.

Another famous World War I pigeon was known as Cher Ami — his moment of heroism came during the Meuse-Argonne Offensive in the fall of 1918.

The German Army surrounded elements of the 77th Division for five days, at one moment confusing the Americans as they accidentally shelled their own men in an attempt to fire at the enemy.

Messages were unable to get to U.S. commanders, so Cher Ami was released as the division’s last hope. Like Wilson, Cher Ami flew through a barrage of gunfire, also sustaining injuries to his leg and chest. But he successfully delivered the message, ending the friendly fire.

The French even awarded Cher Ami the Croix de Guerre with Palm, a military decoration, for his service.

Military carrier pigeons were again used in World War II. In that war, 32 pigeons were awarded the United Kingdom’s Dickin Medal for their heroic actions.

Loved or loathed, feral pigeons as subjects in ecological and social research

Loved or loathed, feral pigeons as subjects in ecological and social research

The feral pigeon (Columba livia) carries with it a reputation that runs counter to conservation: it is feral, exotic and invasive and even considered down right filthy. But upon closer inspection, the pigeon could be a subject worthy of study for both ecological and social science purposes and highlight the importance of urban species in ecology. This insight on pigeons occurred during an urban ecology study that focused on habitat and population dynamics of the birds and is also supported through an extensive literature review. As a nearly ubiquitous species, we discuss how important pigeons are as a prey-base for numerous raptors and underscore our position by highlighting several studies on the biological uptake of environmental contaminants that may have benefited from including the pigeon as part of the research. We further our stance on the importance of pigeons in urban ecology by highlighting additional concerns such as zoonotic disease and climate change. We expand our case by turning to the social construction of nature, the importance of public participation in conservation. Once again, the ubiquitous presence of pigeons lends itself well to citizen science in ecology and conservation, especially to show trends across a range of geographic locations. In short, this commentary strives to reconceptualize the feral pigeon, promoting the bird as a valuable asset to ecological and social research in ways that raise awareness for conservation concerns and advance our scientific thinking.

Drastic population fluctuations explain the rapid extinction of the passenger pigeon

Contesting Tradition: The Deep Play and Protest of Pigeon Shoots

Pigeon shoots are examples of “contested traditions” that invite comparison with other controversial spectacles of killing animals, such as cockfights and dogfights. In the United States during the late twentieth century, mass protests of America’s largest public pigeon shoot occurred in Hegins, Pennsylvania. This article offers a folkloristic perspective on the contested tradition by analyzing how the protest rhetorically served to present tradition as a “problem” in the ethical modernization of society. The clash between animal rights protestors and supporters of the shoot became a moral drama based on a clash of rural and cosmopolitan values in modern America that derives from fundamentally different views of human dominion over the land and its creatures. The interpretation of the event hinges on a semiotic layering that takes into ethnographic consideration the different meanings of symbols for various participants in the event. Compromise became impossible in controversies over pigeon shoots because the sides perceived symbols so differently. For protestors, the shooters represented predatory, phallocentric rapists who promoted violence for its own sake, whereas, for supporters, they symbolized a pioneer and biblical heritage based on human dominion over the bountiful land. For protestors, the process of the ritualized shoot perpetuated cycles of abuse and patriarchy; for protestors, it acted to regenerate the land, confirming the wholesomeness of agrarianism. The pigeons could be symbolized as profane, dirty pests or sacred doves of peace. The widely publicized controversy implied larger questions, and fundamental conflicts in America, about the role of tradition in modernity.

Messenger / Homing Pigeons & Their Applications

Messenger / Homing Pigeons & Their Applications

Homing pigeons are called messenger pigeons when they are used to carry messages. Messages have to be written on light, thin paper (such as cigarette paper) and rolled into a small tube that is attached to the bird’s leg. This is called “pigeon post.

They have also been used to carry small light-weight packages, in including smuggling drugs into prisons.

RACING

In recent history, they are mainly used for the sport of pigeon racing. They have been bred for racing and can reach speeds between 60 – 80 miles per hour. They can fly up to 80 to 600 miles in one single day.

In 2010, Jose Ledesma’s pigeons finish a personal racing season in Canary Islands with amazing resultss. Two young birds raced 3 times each from African coast in Morocco. Long Distance Races + 1st Regional Price against 1312 pigeons (National race equivalent in Belgium). Jose made an amazing movie of these pigeons flying over mountains, seas and deserts: http://www.youtube.com/watch?v=IAGKflxwxwI … Further information can be found on his website: http://www.joseledesma.com/ – J. Ledesma, Tenerife – Canary Islands

THE CARRIER OF MESSAGES

During the Franco-Prussian War of 1870–1871, the Prussians had surrounded the city of Paris preventing mail from entering or leaving the city. During the course of the siege, pigeons and mail were regularly taken out of Paris by hot-air balloons. The letters that were sent to Paris were first reduced in size by photography, so that 30,000 letters could be carried on film placed inside a canister. These canisters were attached to pigeons and these birds then flew into Paris. Thirty-five birds carried the same letters, so that if any were shot down, at least one would reach Paris. In Paris, the film was projected on a screen, and the letters were copied by hand and delivered to homes in the city.

These birds have been used to transport short messages across long distances. In fact, historically well-known leaders, such as Julius Caesar and Genghis Khan, have used them to carry important messages across long distances.

One of the world’s best known news agencies, Reuters, started its European business by using 45 trained birds to carry financial news on the continent in 1850. They carried the latest news and stock prices from Aachen in Germany to Brussels in Belgium, travelling the 76 miles in a record-breaking two hours – beating the railway by four hours.

The Chinese used them to deliver mail as long ago as 1000 B.C.
