Four critically endangered mountain bongos arrived in Kenya on their way to their native forests after years in the care of a zoo in the Czech Republic. Bongos, rare antelopes known for their striking stripes, have been declared critically endangered due to poaching and diseases. There are less than 100 mountain bongos left in the wild, according to the Kenyan government. Many were sent to Europe in the 1980s after a major rinderpest disease outbreak killed thousands. It’s the third such return in recent years. After a period of quarantine and acclimatization, the bongos will be sent to the Mount Kenya Wildlife Conservancy, which houses 102 bongos, for a stay before being released into the wild.
