A video went viral showing a hippopotamus running behind a vehicle for several seconds in Puerto Triunfo, Antioquia. ^[1] All wild hippos in Colombia are descended from four animals-three females and one male-shipped by Pablo Escobar to his Hacienda Nápoles estate in 1981. ^[2] Between the towns of Doradal and Puerto Triunfo on the middle Magdalena River in central Colombia, there are an estimated 170 to 220 wild African hippos living in swamps and river tributaries. ^[3] Cornare advised drivers to reduce speed, maintain attention, and never attempt to approach or scare away the animals. ^[4] Cornare, the Colombian environmental authority, warned that encounters with hippos on highways are becoming increasingly frequent in the region. ^[5] In April 2023, a vehicle collided with a hippopotamus on the Medellín-Bogotá highway, killing the animal and injuring the occupants. ^[6] After Pablo Escobar was killed in a rooftop shootout with Colombian police in December 1993, the state took control of the Hacienda Nápoles property but failed to remove the hippos due to the difficulty of capturing and transporting them. ^[7] By 2022, the peer-reviewed population count was ninety-one, growing at 9.6 per cent per year, and by the 2022-2023 field census using drones, the number had risen to between 181 and 215. ^[8]
