Tracks in the snow, hair on a fence, loud cries in the night. Could it be a mountain lion? The mountain lion and other large carnivores once served as nature's check on deer and other prey species. Today, humans control the deer herd, so the natural role of this big cat is gone. There aren't many animals that receive more interest in Missouri than mountain lions. 

Who's in the forest this time of year? Some Missouri owls stick around all year and are especially vocal during the winter months. Get together to discuss some of the owl's amazing adaptations, dissect some pellets to see what they're eating and take a hike to hear what they're saying. Dress for the weather.

Free. For ages 7 and up. 6:30 to 8:30 p.m.
