Zoo animals often receive names from zookeepers and staff members who care for the animals. Zookeepers at the Whipsnade Zoo in London named the red panda cubs born there in 2015 Bert and Ernie, while staff members chose the name Tofu for the cub born at the Detroit Zoo.
Zoos also allow sponsors and donors who support the zoo to name animals. A major donor of the Lincoln Park Zoo in Chicago named red panda cubs born there in June Addison and Clark, after the streets that form the intersection near the entrance to Wrigley Field.
Zoos sometimes turn to the community to name animals as a means of generating interest and increasing attendance. The Smithsonian National Zoo held an online election asking fans to vote for the names of Andean bear cub twins born there in March 2015, with voters selecting the names Mayni and Muniri.
