Here's his dad:
(Note the bifurcating growth form of the antlers.)
And here are some of his male cousins:
Disney and his slaves...er...animators...worked in southern California, where the native deer is the Mule Deer, Odocoileus hemionus. So although Bambi (written by German author Felix Salten) was originally a European deer, Disney made him into a Mule Deer (a.k.a., Black-tailed Deer):
But did the Disney people do their homework?
Remember when Bambi fell in love? And then was challenged by another deer for Faline's affections?
Check out the rival's antlers:
Clearly, Ronno (the rival) is a different species, namely a White-tailed Deer (Odocoileus virginianus). His antlers form a circular "crown" (see the image of a real Whitetail to the right), unlike the two-pronged branching antlers of Bambi and his O. hemionus conspecifics.
Closely related species, yes. But would this bode well for Faline's fawns, should Bambi lose the fight?
In this case, there's more to the species difference than antlers. The two species of deer also have significantly different gaits, evolved in two different habitats for most effective predator avoidance.
In 1992, Susan Lingle of the University of Calgary published her study (Behaviour, 1992; v 122) of the gaits of Mule Deer, White-tailed Deer, and their hybrids. Hybrids are sometimes found in areas of Calgary (and possibly other areas where the two species exist in close proximity) where large predators have been removed by humans.
But here's the rub...
What does this mean for Faline and her suitors?
Bottom Line: Hybridization could spell trouble, if Faline doesn't exercise her right to behavioral reproductive isolation, and reject Ronno's advances, even if he beats the stuffing out of Bambi.
