We stumbled upon this guy just after sunset just as we were about to call it a day and head back to the lodge. Queen Elizabeth National Park in Uganda, Africa is known for its tree climbing lions. It is believed that these lions climb trees in order to get away from tsetse (Pronounced "Se, Se") flies, which are large flies that have a really nasty bite and commonly carry sleeping sickness. Tree-climbing lions aren't very common. While cubs climb trees for fun, adult lions rarely do and are only known to do so in the reserves of Uganda and Tanzania. In the wild, males seldom live longer than 10 years, as injuries sustained from continual fighting with rival males greatly reduce their longevity. In Uganda Lions are becoming quite rare, having seen a major population decline of 30â€“50% over the past two decades. Sadly, the majority of this decline can be attributed to local farmers, who poison the lions to protect their livestock from being eaten. Last year, 12 Lions were killed in Queen Elizabeth alone. While the government in Uganda is taking steps to combat this problem, disorganization and corruption severely inhibit progress.
