Colorado wildlife officers are on the lookout for a Patagonian mara roaming a Lakewood park, though it’s unclear how the large rodent native to South America made its way to metro Denver. Bear Creek Lake Park rangers and visitors have reported several encounters with what appears to be a Patagonian mara, an Argentine animal that looks like a mix between a rabbit and a capybara. One visitor posted a video of the animal on Reddit after coming across it on a trail while mountain biking. Maras weigh between 17 and 35 pounds and Lakewood officials believe the animal spotted on park trails may have been a pet, city spokesperson Amber Thill said in an email.
