An adorable Syrian brown bear appeared to be challenging himself to a breath-holding competition in a pond at a sanctuary in Otisville, New York, recently.The footage shows 28-year-old Leo dunking his head under water for extended periods of time. According to the sanctuary website, Leo is their “most clever bear and loves to play with balls and toys.”Founded by Jim Kowalczik, Susan Kowalczik, and Kerry Clair in 2015, the Orphaned Wildlife Center nurtures its animal residents in the hope they can be returned to the wild.The center often shares videos and updates about the animals in its care to its YouTube channel and Facebook page.
