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.
During some migrations, the flocks flying overhead would stretch for over a mile and could take several hours to pass. It would have been impossible to imagine a North American skyline without them. Yet somehow the species went from being one of the most abundant birds in the world to extinction in only about 100 years. What happened?
Colonial hunters happened. The pigeon meat was commercialized and recognized as cheap food, especially for slaves and the poor, which led to a catastrophic hunting campaign on a massive scale. Furthermore, due to the large size of their flocks, the birds were seen as a threat to farmers. In fact, in 1703 the Catholic bishop of Quebec actually excommunicated the entire species.
The last known Passenger Pigeon, named “Martha”, died in captivity on September 1st, 1914, in Cincinnati, Ohio. In 1896, the last flock of 250,000 birds were slaughtered by hunters despite the knowledge that it was the last flock of that size left.
The first recorded account of the Golden Toad was by herpetologist Jay Savage in 1966, and the last sighting of the species was made in 1989. The toad, showcased by its brilliant golden orange colorization, was native to the tropical cloud forests which surround Monteverde, Costa Rica.
Their extinction symbolizes a large scale decline in amphibian numbers worldwide over the last several decades, which has likely been caused by global warming and climate change. In fact, famed Australian biologist Tim Flannery has described the extinction of the Golden Toad to be the first demise of a species due primarily to global warming.
The Caribbean Monk Seal was the only known seal which was native to the Caribbean Sea and the Gulf of Mexico. It is also the only species of seal to go extinct directly due to human causes. It was officially declared extinct on June 6th, 2008, although the last recorded account of the species was made at Serranilla Bank between Honduras and Jamaica in 1952.
Their eventual demise, brought on by human hunting, was symbolized during Columbus’ 1494 voyage, when the tiny seals were described as “sea wolves” and 8 were recorded to have been killed and slaughtered for their meat.
