A photo taken by wildlife photographer Vince Burton inside the Queen Elizabeth National Park in Uganda shows a lion resting in a tree. Only two lions have been documented scaling trees to relax on their branches.

A lioness gets comfortable for a catnap in a tree in Uganda's Queen Elizabeth National Park. "Lions are not known for their tree climbing abilities, unlike other big cats such as leopards," Vince Burton said. "However, these lions in the Queen Elizabeth Park in Uganda have adapted and use the tree climbing to cool down in the warm afternoon sun." /VCG Photo
