In the meadow scene, Faline's eyes change from blue to brown then back to blue in later scenes.
When Bambi looks in the pond while in the meadow and sees Faline's reflection, he repeatedly looks at both his and her reflections. After Faline giggles, Bambi stops in awe and blinks twice. On the second blink, the reflection's eyes do not blink with Bambi's eyes.
When Bambi sees the possums hanging upside down from a tree, they are oriented such that the shortest is hanging on the left and the longest is on the right. Bambi rotates his head to look at them. Doing this, the longest should now be on the "left," but the longest is still on the right.
When Thumper is laughing at Bambi just after meeting Flower, he rolls on his back and his normally white tail is brown. When he rolls back onto his belly, his tail is white again. This appears to have been corrected for the 2005 DVD release.
When the animals gather around to see new-born Bambi, the spots on Bambi's coat disappear for a moment.
Skunks, although not particularly active in winter, do not hibernate.
The owl says that all animals, like the birds, become "twita-paited" in the spring. That time for deer is the fall rut. However, Bambi and Faline's twins are born in spring which is correct.
Thumper consistently thumps his hind leg on the ground for various reasons: announcing positive news, showing off, joy, calling his family, etc. In real life, rabbits only thump to warn other rabbits about concern for danger or unfamiliar surroundings.
One baby raccoon disappears as it comes out of the water after the fire, instantaneously appearing elsewhere. This has been corrected on the 2005 DVD as well as the Blu-Ray.
When we first meet Faline as a fawn, her pond reflection stands up as the camera moves back, while she stays still.
When Bambi walks backwards as an attempt to get away from Faline, he's missing two hooves.
When Bambi's mother says, "Bambi. My little Bambi," her eyes lose her pupils for a second.
Before Bambi tries to talk, his eyes are mistakenly drawn to look as if they have split for a short second while the little songbirds fly around his head.
