Although the animators had animated deer in Snow White, they were animated, in the words of Eric Larson, "like big flour sacks". Disney wanted the animals in Bambi to be more realistic and expressive than those in Snow White. He had Rico LeBrun, a painter of animals, come and lecture to the animators on the structure and movement of animals. The animators visited the Los Angeles Zoo and Disney set up a small zoo at the studio with animals such as rabbits, ducks, owls, and skunks, and a pair of fawns named Bambi and Faline so that the artists could see first-hand the movement of these animals. Rico LeBurn's sketches depicted realistic animals, but as characters they lacked personality. Marc Davis created the final design of Bambi by incorporating LeBurn's realistic study of deer anatomy but exaggerating the character's face by making his proportions baby-like (short snout, big eyes, etc.). Although there were no humans in Bambi, live-action footage of humans was used for one scene: actress Jane Randolph and Ice Capades star Donna Atwood acted as live-action references for the scene where Bambi and Thumper are on the icy pond. The animators learned a lot about animals during the film's production, giving them a broader spectrum of animation styles to use in future projects.
