Endemic to the Falkland Islands, just off the coast of Patagonia, the Wolf that once called the area home is now extinct. Identified in 1690, the species likely reached the area during the last glacial stage. The Falklands Wolf was present in the 1830s when Charles Darwin visited, but it was already reaching a state of decline. The last of its kind is believed to have been killed in 1876 at Shallow Bay. The species was notoriously curious and tame, and often approached humans. As easy prey, humans killed off the species for its meat, and fur. Scottish settlers began laying poison traps and setting fire to bush wood to stop the Wolves from attacking their sheep.
Christmas Island Pipistrelle Bat
The Bat was once endemic to Christmas Island, south of Indonesia in the Indian Island and was a widespread and abundant species on the isolated island. The species typically roosted under bark, within dead foliage and foraged within the forests feeding on small flying invertebrate, such as moths. The reason for the decline of the Christmas Island Pipistrelle Bat are unclear, although it is believed to be due to the introduction of invasive species, such as the Common Wolf Snake (Lycodon capucinus) and the Feral Cat (Felis Catus) which disturbed their roosts.
The Golden Toad was found only to exist in Costa Rica, in a particular zone known as Reserva Biológica Monteverde. It was once a common species, and last bred normal numbers in 1987. One year later, only eight males and two females could be located. Despite being a protected species the Golden Toad declined rapidly, likely due to the restricted range, airborne pollution and chytridiomycosis which is an infectious disease caused by fungus and is strongly mitigated by high temperatures.
