Walt Disney wanted to have realistic detail in this animated movie. The artists learned from animal experts. They also visited the Los Angeles Zoo. A pair of fawns (named Bambi and Faline) were shipped from the area of present-day Baxter State Park in Maine to the studio so that the artists could see for themselves how these animals move. The source of these fawns, from the Eastern United States, gave the company the idea to change Felix Salten's Roe Deer to a mule deer. The background of the movie was also the Eastern woodlands. One of the earliest and best known artists for the Disney studio, Maurice "Jake" Day, spent a lot of weeks in the Vermont and Maine forests. He drew pictures and took photographs of deer, fawns, and the wilderness areas around them.
