The Racine Zoo’s newest residents have arrived just in time for colder weather; an arctic fox sibling pair and two male African penguins.

Echo and Luna are brother and sister born May 20 at the Great Bend-Brit Spaugh Zoo in Kansas. Zookeepers describe Echo as outgoing and vocal when he wants attention while Luna is a little more reserved.

“Both are very playful high-spirited animals and just make a fabulous addition here at the Racine Zoo,” a release from the zoo reads.

Arctic foxes are built for the cold and can weather temperatures as low as -58 degrees Fahrenheit. They live in a variety of locations throughout the Arctic Circle, including Alaska, Canada, Greenland, Russia, Norway, Scandinavia, and Iceland. They get their food sometimes by following polar bears and eating whatever the bears leave behind.

“The animal care staff is currently working with both of them to learn their manners when interacting with staff; to sit when taking food by hand, or when getting attention,” said Theresa Donarski, Curator of Conservation & Animal Care, in the release. “Long term goals are harness training to take them out on programs because they will make great animal ambassadors for their species.”

New members of the Racine Zoo family also include Stanley and Dassen from the NEW Zoo in Green Bay, whom the zoo will trade for Mr. Bill and Blue/Green. Bill and Blue were both born in Racine, and they are moving to the NEW Zoo as part of the Species Survival Plan.

“We are sad to see our penguins leave, but in turn, very excited to gain and contribute to the SSP program,” the release continues.
