Who were they??
Martha the Passenger Pidgeon
The story of the Passenger Pigeon is one of the most tragic extinction stories in modern times. As recently as around 200 years ago they weren’t anywhere near extinction. In fact, they were actually the most common bird in North America, and some reports counted single flocks numbering in the billions. Pigeon meat was commercialized and recognized as cheap food, especially for slaves and the poor, which led to a hunting campaign on a massive scale. Furthermore, due to the large size of their flocks, the birds were seen as a threat to farmers. The last Passenger Pigeon, named Martha, died alone at the Cincinnati Zoo at about 1:00 pm on September 1, 1914.
Celia the Pyrenean Ibex
The Pyrenean Ibex has one of the more interesting stories among extinct animals, since it was the first species to ever be brought back into existence via cloning, only to go extinct again just seven minutes after being born due to lung failure. The Pyrenean Ibex was native to the Pyrenees, a mountain range in Andorra, France and Spain. Its situation has been critical since the beginning of the 20th century, when it was estimated that the Pyrenean population in Spain numbered only about 100 individuals. Since the beginning of the 20th century, the population never rose above 40 individuals. In 1981, the population was reported to be 30. At the end of the 1980′s the population size was estimated at 6-14 individuals. The last naturally born Pyrenean Ibex, named Celia, died on January 6th, 2000, after being found dead under a fallen tree at the age of 13. That animal’s only companion had died just a year earlier due to old age.
Lilio the Baiji River Dolphin
The Baiji population declined drastically in recent decades as China industrialized and made heavy use of the river for fishing, transportation, and hydroelectricity. As China developed economically, pressure on the river dolphin grew significantly. Industrial and residential waste flowed into the Yangtze. The riverbed was dredged and reinforced with concrete in many locations. Ship traffic multiplied, boats grew in size, and fishermen employed wider and more lethal nets. Noise pollution caused the nearly blind animal to collide with propellers. In the 1970s and 1980s, an estimated half of Baiji deaths were attributed to entanglement in fishing gear. Only a few hundred were left by 1970. Then the number dropped down to 400 by the 1980s and then to 13 in 1997 when a full-fledged search was conducted. The dolphin was declared functionally extinct after an expedition late in 2006 failed to record a single individual after an extensive search of the animal’s entire range.
