Colombian authorities are set to cull up to 80 feral hippos descended from animals once owned by notorious drug kingpin Pablo Escobar in the country's Magdalena River valley, where the beasts have been wreaking havoc on native species and villagers since their introduction in the 1980s.

The decision to cull the hippos has been taken due to the significant threat they pose to the local ecosystem and human settlements, with the large feral pachyderms competing with native animals for food and habitat, and in some cases attacking villagers who venture too close to their territory. The hippos, which were originally part of Escobar's private zoo at his Hacienda Napoles estate, were left to roam free after the drug lord's death in 1993, and have since thrived in the region's fertile wetlands and waterways. Colombian officials have deemed the cull necessary to restore balance to the ecosystem and protect both the environment and local communities.

The presence of feral hippos in Colombia is a legacy of Escobar's notorious reign, during which he imported exotic animals to populate his private zoo, including hippos, giraffes, and elephants. The hippos, in particular, have proven to be a highly invasive species, capable of adapting quickly to new environments and outcompeting native animals for resources. The cull is part of a broader effort by Colombian authorities to address the environmental and social impacts of Escobar's activities, which include the destruction of habitats and the displacement of local communities. The hippos' presence has also raised concerns about the potential spread of disease and the impact on biodiversity in the region.

The cull is expected to be carried out by trained wildlife professionals, who will use humane methods to kill the hippos, with the aim of minimizing suffering and preventing further disruption to the ecosystem. The move has been welcomed by local residents, who have long complained about the dangers posed by the feral hippos, and by conservationists, who see the cull as a necessary step towards restoring the balance of the ecosystem. However, the operation is also likely to be controversial, with some animal welfare groups expected to oppose the killing of the hippos, and to argue that alternative solutions, such as relocation or sterilization, should be explored instead.
