Brothers Jacob and Tiv in Queen Elizabeth National Park, Uganda
Alex Blaczkowski
A pair of lion brothers have completed the longest recorded swim of their kind, crossing waters infested with hippos and crocodiles for around 1.5km.
The swim, the equivalent of an Olympic triathlon, was the duo’s fourth attempt to cross the Kazinga Channel in Uganda’s Queen Elizabeth National Park and was recorded at night with a thermal camera mounted on a drone.
The lions had to abandon an earlier attempt after encountering a larger animal, possibly a hippopotamus or Nile crocodile, which was also seen on footage.
What makes the effort even more amazing is that one of the lions, named Jacob, only has three legs.
Jacob says he’s had a very difficult life. Alexander Bratskovsky While at Griffith University in Australia, he was gored by a buffalo, his family was poisoned to sell lion parts, he was caught in a poacher’s trap and eventually lost his leg to a poacher’s iron trap.
Catching the swimming scene on film was unexpected, as Braczkowski and his colleagues were actually keeping an eye on the two lions to determine whether Tibu, Jacob’s brother, was feeding and supporting his sibling.
“The brotherhood of lions goes far beyond the limitations of an injury like losing a leg,” Blaczkowski said.
The researchers believe the brothers probably crossed the strait to reach a lioness whose roaring they had heard two kilometers away. They say the crossing was a straight line of 1.1 kilometers, but taking into account maneuvers, they estimate the lions swam closer to 1.5 kilometers.
“It’s amazing to see the individual capabilities and courage of different species in passing on their genes,” Blaczkowski said. “A human being can’t swim across that channel in the middle of the night, but a lion, even a three-legged lion who has had almost everything taken from him, will jump in.”
Braczkowski said the lions in Queen Elizabeth National Park were under huge pressure from as many as 60,000 people living within its boundaries, as well as cattle farming, wildlife poaching and the occasional agricultural crop cultivation.
“The lion population in the park has almost halved from 72 to 39 in the past five years, so male lions are spending a lot of their time searching for new females,” he said.
Females are more vulnerable because they tend to congregate in larger groups, and leaving the poisoned carcasses increases the risk of multiple deaths, he added.
“The ratio in the park is currently one female to two males, but in a healthy population it should be one male to two females.”
Team Members Duane Biggs Researchers from Northern Arizona University say long-term solutions need to be found to protect both people and lions in the park.
“The three-legged lion swimming through crocodile-infested waters in search of a mate and caught in a poacher’s trap is a symbol of a protected area in distress,” he said.
