BISMARCK, N.D. (AP) — There's some monkey business going on at Dakota Zoo in Bismarck this spring.

The $750,000 Heringer Family Primate Center is scheduled to open in mid-June.

Zoo Director Terry Lincoln tells The Bismarck Tribune the 4,000-square-foot building will double the indoor space for the zoo's seven species of primates, and enable the animals to go inside and outside as weather permits.

Lincoln says the center's heating, cooling and ventilation system is designed to keep the indoor viewing area and lobby virtually odor free.

The current monkey house will be remodeled and used as a winter home for emus and wallabies.
