Passenger Pigeons were unique in the world not only because of the vast numbers, but also because of the manner in which they roosted, nested, flocked, and migrated. The great American naturalist John James Audubon wrote this account of the passing of a flock of what he later estimated to be more than 1 billion pigeons in the Fall of 1813:
“As I traveled on, the air was literally filled with pigeons. The light of noon-day was obscured as by an eclipse, and the continued buzz of wings had a tendency to lull my senses.Before sunset I reached Louisville, Kentucky. The pigeons passed in undiminished number, and continued to do so for three days in succession. The people were all in arms. The banks of the Ohio were crowded with men and boys, incessantly shooting at the pilgrims, which flew lower as they passed over the river. Multitudes were thus destroyed. For a week or more, the population fed on no flesh other that of pigeons, and talked of nothing but pigeons.”
Passenger Pigeons seemed to have evolved a survival strategy based on predator satiation. The birds nested in the northern forests each spring and summer where a pair would raise just a single offspring each mating. After a few weeks of continuous feeding, the parents would force their fattened youngster (called a squab) from the nest to the ground where it remained until first flight a few days later. In a large colony, hundreds of millions of squabs littered the forest floor helpless to their many predators. But the local populations of foxes, wolves, bears, boars, birds, snakes, rodents and other creatures that feasted on the squabs could eat only a small fraction of the squabs before they flew away. The next year, that colony would find a different nesting site: the Passenger Pigeon was the most ephemeral of prey.
The gigantic colonies may have moved from site to site not because of predators, but because of their effect on their nesting and roosting grounds. Larger colonies covered anywhere between 30 and 850 square miles. Descriptions of those sites indicated that nearly every tree in the area supported a nest, and some had as many as 500 nests. Under such weight tree branches collapsed and trunks more than 2 feet in diameter were snapped off at the base. The droppings of the birds blanketed the forest floor and killed the understorey. Even the most productive forests could support such a brood for a few months at most.
Their prime food source were the plentiful acorns, chestnuts, beech nuts, and hickory nuts that littered the forest floor. But as their forests were logged to provide land and timber for the rapidly expanding US population, they became agricultural pests, and their slaughter was officially supported by local, state, and federal governments. Not that folks needed much encouragement. Eastern palates had developed a taste for the cheap and plentiful pigeon meat; and Southern slaves, when they received any meat at all, were almost exclusively given pigeon. Their feathers stuffed pillows and mattresses and were used for decoration and fashion. And of course the pigeons were shot for sport, both in the wild and in carnival booths where the docile birds proved easy targets.
It didn't take long for a group of professional pigeoners to emerge that helped meet the vast demand for pigeons and their fatty squabs. These men--whose numbers are estimated to have been between several hundred and a few thousand--tracked the nomadic pigeon colonies across the US. Later in the century, they made use of the fledgling telegraph technology to locate their swiftly-traveling prey.
Their tactics were brutal but efficient. Boys used long sticks to knock the birds and their young from nests where they were then clubbed as they rained down. Fire and sulphur were used to suffocate the birds as they roosted. Live pigeons with eyes sewn shut were also used as decoys to attract other pigeons (they were called "stools", hence the phrase "stool pigeon"). Of course the shotgun was an ever-popular option. One published account quoted a man who recalled shooting blindly into a tree at night and collecting 18 birds. Migrating flocks provided a steady stream of birds that flew so close that 50 could be brought down with a single blast. When the bounty proved too much for a single man or even a single town to use, hogs were loosed to clean the ground of dead pigeons and helpless chirping squabs.
The pigeons were killed where they nested, where they roosted, where they fed, and as they flew. They were pursued and harried from town to town and state to state. By the mid 19th-century their numbers had noticeably declined, and by 1880 commercial hunting was no longer profitable. But because of the peculiar habits of the Passenger Pigeon, hunting proved easy and plentiful right until the end. Indeed, their final big season was to be their most successful ever.
In the summer of 1878, the last large breeding colony of Pigeons arrived near Crooked Lake in Petosky, Michigan. The flock covered 40 square miles and for three months yielded over 50,000 birds a day to hunters. One hunter reportedly killed 3,000,000 of the birds and according to one account earned $60,000--more than $1 million in today's dollars. All told, between 10 and 15 million birds were dressed, packed for sale, and shipped out of Petoskey that summer. Estimates of the total number slaughtered vary widely but agree that the harvest rate was upwards of 90%. Though moderate-sized colonies nested in Michigan in 1881, the bird was never again spotted in that state after 1889.
In 1896, the last remaining flock of Passenger Pigeons settled down to nest. All 250,000 were exterminated in one day by sportsmen who gathered to kill what was advertised as the last wild flock of the birds. Fully aware of the rarity of the species, a 14-year-old boy in Ohio shot the last wild pigeon in the spring of 1900.
All efforts at breeding in captivity failed. The Passenger Pigeon reproduced slowly, had odd mating habits that prevented crossbreeding, and were seemingly incapable of breeding within their species outside of large colonies. One by one, pigeons in captivity died without producing offspring. Finally on September 1st, 1914 the last Passenger Pigeon fell off her perch and died. Martha had lived to be 29. She was frozen in ice and shipped to the Smithsonian Institute in Washington where she was skinned and stuffed. She remains there on display. Reports of sightings continued into the 1930s, but despite hefty rewards, none were confirmed.
Though it was a shameful deed, it was more than simply human hunting that doomed the Passenger Pigeon: it was our very presence. Its cousin, the Mourning Dove, is better adapted to living with humans and is so numerous that 30 million are killed each year with little threat to the remaining 400 million. The unfortunate truth is that had the Passenger Pigeon not been hunted to extinction, it probably could not have survived without the vast forests that supported its great colonies. Those forests no longer exist, and though they are growing back in some areas, they are much smaller and more fragmented. It seems that the Passenger Pigeons are no more compatible with modern man than were the forests that they called home.

The Tyrant of Clipperton Island (1914 AD)
For a tropical island, Clipperton doesn't have very much going for it. The tiny, ring-shaped atoll lying 1,000 kilometres off the southwest coast of Mexico is covered in hard, pointy coral and a prodigious number of nasty little crabs. The wet season from May to October brings incessant and torrential rain, and for the rest of the year the island reeks of ammonia. The Pacific Ocean batters the island from all sides, picking away at the scab of land that rises abruptly from the seabed. A few coconut palms are virtually the only thing that the island boasts in the way of vegetation. Oh, and the sea all around is full of sharks. It isn't much of a surprise that Clipperton Island is decidedly uninhabited.
This was not always the case, however. Over the course of the island's modern history, four different nations--France, the United States, Britain, and Mexico--fought bitterly for ownership of Clipperton. It was desirable both for its strategic position and for its surface layer of guano, since the droppings of seabirds (as well as bats and seals) are prized as a fertiliser due to their high levels of nitrogen and phosphorus. Each of the four countries in turn attempted to maintain a permanent presence on Clipperton between 1858 and 1917. When a
contingent of Mexican settlers did finally gain a toehold on the atoll, they were forgotten and left stranded on the island with a delusional man who seized the chance to become a dictator.
The island's English name comes from a tenuous association with a British pirate, but the first modern explorers to claim Clipperton were the French, in 1858. Their intention was to land on the island's shores and read out a proclamation, but this proved to be difficult; approaching the island with the ship posed a significant risk of running aground on the coral reef, and smaller rowboats were thwarted by sharks and fickle tides. Desperate, the French resorted to sailing around the perimeter of the island while reading the proclamation out to its coastline. Then, satisfied, they departed. Although they were aware of the guano, they felt it was likely to be of inferior quality, so they left it at that.
The next country to claim the island was the United States, in 1892. Unlike the French, the Americans suspected that Clipperton's guano was extremely valuable, and they annexed the island under the auspices of the U.S. Guano Islands Act. A small crew of American miners spent the next few years on the island attempting to turn a profit, but poor market conditions and expensive resupply-trips intervened. Then, in 1897, the Mexicans decided they'd had enough of the United States occupying an island so close to the Mexico coast. A small group of Mexicans sailed over, lured two of the three Americans away, and left a Mexican flag in place of the American one that had been flying from a forty-foot pole. The U.S. backed off and gave up its claim to the island, but France and Mexico were unable to come to an agreement. To complicate matters, an English company then decided to try a guano-mining operation of their own, insisting that they did not care who owned the island. Mexico allowed them to proceed.
The British had high hopes, and got straight to work building a new settlement on Clipperton. They put up houses, constructed an enclosed soil garden, and planted more palms. But the island was pretty much as inhospitable as ever, and the mining, which began in 1899, did not prove to be lucrative. Although the Clipperton guano was of fairly good quality, there was now too much competition in the market for it to be worthwhile. By 1910 the British decided that the effort was futile, and removed all of their employees except for one island caretaker. The island's other claimants, France and Mexico, signed an arbitration treaty leaving the question of Clipperton's ownership to King Victor Emmanuel III of Italy. He began his deliberation.
In the meantime, Mexico sent over a group of 13 men from their army to guard the island, including a de facto governor by the name of Ramón Arnaud. Wives and servants followed, and a number of children were born on the island in the early 1910s. An American ship was wrecked on the island in 1914; rescue came quickly, and the Americans advised the Mexicans to leave. Arnaud declined; all he did was expel the last remaining Brit from the island, sending the man and his family away with the Americans. With their last employee expelled, Britain stopped paying attention to Clipperton; meanwhile, Mexico was taking increasingly little notice of it themselves owing to a developing revolution in the country. Without any explanation, ships stopped arriving at Clipperton. The tiny community was dependent on the mainland for food and information, and soon their cache of supplies began to dwindle. In this case, no news was bad news.
At this point there were approximately 26 people on Clipperton Island: 13 soldiers, about 12 women and children, and a reclusive lighthouse-keeper named Victoriano Álvarez who lived alone at the base of a sheer cliff below the lighthouse that the Mexicans had constructed in 1906. The island's vegetable garden had been lost to the elements, and the only types of food available from the island itself were birds, bird eggs, and fish. There were also a few coconuts every week, but these were not a sufficient source of Vitamin C, and the islanders--especially the adult men--began getting sick with scurvy. One by one, they started dying; their fellow islanders buried their bodies deep beneath the sand in order to make them inaccessible to the crabs. Arnaud was mildly alarmed, but he was reluctant to abandon the island. At any rate, he knew that any attempt to reach the mainland would probably end badly; the one boat that the islanders owned did not have enough fuel for a trip over to Acapulco, and rowing it would be extremely difficult with only five men remaining on Clipperton, all of them suffering the effects of undernourishment and vitamin-deficiency.
The situation took another turn for the worse when Arnaud spied a distant ship, and talked the three other soldiers into joining him in the rowboat and going to the ship for help. Out on the water there was no sign of any such ship; it is quite possible that Arnaud had been deceived by an illusion. Angry, the three other soldiers attempted to overpower Arnaud and seize his weapon. Several of the wives watched helplessly from shore. The struggling mass of men fell overboard, and all of them drowned in the waves. Only hours later, two unrelated emergencies arose almost at once: a hurricane appeared offshore, and Arnaud's heavily pregnant widow went into labour with the couple's fourth child. The women and children took refuge in the cramped basement of the Arnauds' house, and Alicia Rovira Arnaud gave birth to a son, Angel. Mother and baby survived, but the islanders emerged from the basement to find their buildings torn to pieces.
Just then, Álvarez the hitherto-unassuming lighthouse-keeper abruptly arrived at the destroyed settlement, collected the weapons, and threw them into the deep waters of the lagoon. Saving one rifle for himself, he announced to the women and children that he was now the king of the island. With that, he began a campaign of enslaving the women for whatever purposes he desired. One mother-daughter pair who refused to obey him were raped and shot to death. The rest were given regular beatings at the minimum.
Months passed, with Álvarez borrowing whichever female islander he wanted whenever he wanted: when he'd had enough of 20-year-old Altagracia Quiroz, he moved on to 13-year-old Rosalia Nava, and then 20-year-old Tirza Randon. The strong-willed Randon was far and away the most outspoken about her hatred of Álvarez, but was unable to think of a way to escape. “King” Álvarez was aware of the chance of being discovered by passing ships, especially since he knew that Alicia Rovira Arnaud would immediately tell all to any outsider who appeared. Consequently, Álvarez singled out Arnaud for threats, telling her that he would kill her the moment anyone from the outside world came into view.
Álvarez was almost certainly mentally ill. He had been belittled for much of his life on account of his African heritage, which was as stigmatised in Mexico as it was in the United States at the time. Years of isolation on Clipperton could only have amplified his anguish; lighthouse-keeping was notorious for causing madness.
Somehow, life at the colony went on for nearly two years under Álvarez's reign of terror. The women and children divided up the coconuts and the leftover scraps of materials following the storm. Álvarez went on cycling through his trio of women. In the middle of July 1917, he got tired of Tirza Randon again, and decided that his next target was Alicia Rovira Arnaud, whom he had not pursued earlier. He picked up his rifle, took Randon back to the main settlement, and informed Arnaud that she was to present herself at his hut by the lighthouse the following morning. Sensing an opportunity, Randon informed Arnaud, “Now is the time.”
On 18 July 1917, Arnaud and her seven-year-old son, Ramón Arnaud Jr., set out for the lighthouse-keeper's hut, accompanied by Randon. Álvarez, sitting outside roasting a bird, was in uncharacteristically good spirits; however, he was not happy to see Tirza Randon back so soon. “What are you doing?” he asked her, and attempted to shoo her off. Instead, she ran into Álvarez's hut, returned with a hammer, and upon a signal from Arnaud, took the hammer in both hands, swung, and struck Álvarez in the skull. And then a second time. Arnaud sent her son inside the hut, and meanwhile Álvarez shook off Randon, grabbed an axe, and went after Arnaud. Arnaud yelled to her son to get Álvarez's rifle. He did, but in the meantime Randon had landed another good swing on Álvarez, and he fell to the ground. She had most likely killed him by this point, but she allowed her rage to lead her to a knife
, return, and stab the body repeatedly. In hysterics, Randon then began slashing at the dead man's face. The dictator of Clipperton Island had met his end.
Even as the three still stood alongside the expired tyrant, little Ramón spotted something on the horizon that the community had not seen in nearly two years: a ship. The USS Yorktown was an American gunboat patrolling the west coast of North and South America, looking for German U-boats in accordance with a rumour that the Germans had established secret radio and submarine bases in the Pacific. Clipperton Island fell right along the Yorktown's route, and certainly qualified as a potential hiding-place for the enemy.
The Yorktown circled Clipperton and made an attempt to send a smaller boat ashore, but the Americans were unable to reach the island and the boat returned to the ship. The islanders were devastated to see this retreat; just when they had caught sight of an opportunity to escape, it had disappeared. The women even briefly discussed whether they should just give up and either shoot each other or drown themselves in the lagoon. Fortunately, though, the Americans made a second attempt at sending their boat to Clipperton's shores, and this time they were successful.
Arnaud met the Americans and frantically indicated the islanders' desire to leave as soon as possible. Several members of the crew accompanied the women to the settlement in order to collect a few possessions, and others investigated the lighthouse. The Americans noted that the children were all small for their ages due to malnutrition; in particular, two-year-old Angel Arnaud was suffering from rickets and could not walk. Eleven-year-old Francisco Irra carried Angel on his back all the way to the American boat, and the sailors took the Clipperton Island survivors--three women and eight children--to the Yorktown. Álvarez's body was left for the crabs.
