Deer
Deer are a species of hoofed mammals known to reside in Equestria; they are related to Reindeer.
Biology
Male deer grow antlers, while females do not. Both sexes range in size from about the same stature as a typical adult pony to much larger.
Abilities
Some deer seen resemble human world deer, as they have not demonstrated the power of speech or beyond animal-intelligence. The Deer who inhabit the Kingdom of Thicket in the Everfree Forest are the complete opposite, being capable of not only speech and understanding but also possessing their own Magic.
