It took just 10 minutes for a dozen prairie dogs to outwit the creators of the Maryland Zoo's new $500,000 habitat.
Aircraft wire, poured concrete and slick plastic walls proved no match for the fast-footed rodents, the stars of a new exhibit that opens today.
As officials were promoting the return of the zoo's 28 prairie dogs - their former digs had been out of sight in a closed section of the animal preserve for more than four years - some of the critters found ways to jump, climb and get over the walls of their prairie paradise, a centerpiece exhibit just inside the zoo's main entrance.
None got away, but for a few anxious minutes, they found every weakness in the enclosure built to hold them. Zookeepers had to bring out nets to catch escapees.
When the animals were let out of their crates into their new habitat Wednesday, not all sought to escape. More than a few seemed happy to take a noontime siesta. Others were more interested in a lunch of biscuits, kale, apples, carrots, alfalfa hay and mulberry leaves.
But a few intrepid prairie dogs tried to find their way out, sending keepers scrambling to plug escape routes.
An hour later, just as zookeepers thought everything was under control, one rodent made it to the top of the wall. A dozen workers closed in. The prairie dog seemed to think better of it and jumped back into the enclosure.
"They find all the weak spots and exploit them," said Karl Kranz, the zoo's vice president for animal programs and chief operating officer. "But they are so fun to watch as they play, squabble, groom and bark with others in their colony."
The new Prairie Dog Town took several months to build on the site of what had been the Kodiak bear exhibit. With its waist-high glass walls, the habitat permits children and prairie dog to get to know each other face to face. Zoo officials said prairie dogs have been one of their most popular and requested attractions.
Keepers released the animals Wednesday so they could begin digging their burrows in the 80 truckloads of sand and clay soil. Within hours, the prairie dogs had made at least one sleeping burrow under a tree limb.
"It's like they were dropped off cold in the middle of the desert," Kranz said, adding that after 24 hours they "had gotten very serious about digging their burrows."
