Buck Antelope means male antelope with visible horns and a dark cheek patch at the base of the ear.
Doe means an adult female antelope or adult female deer.
Fawn means young-of-the-year antelope or young-of-the year deer.
The ability to distinguish between buck and doe antelope is critical to hunters holding licenses valid only for does and fawns and to those hunting in areas where only buck antelope are legal quarry.
Adult bucks are easily distinguished by their long, black horns, which extend beyond the tips of the ears, and by the black cheek patch below the ear at the angle of the jaw. Yearling bucks have shorter horns, usually about as long as the ears, but they also have the distinguishing black cheek patch.
Females often grow horns, which occasionally grow to the length of the ears,but they lack the black cheek patch. Even among fawns, which usually lack visible horns, the black cheek patches distinguish males from females.
