They may stand antiparelled with each other, heads turned away, then, at the same instant, both whip their heads around to face each other. The next level of intensity is a head-on approach with chin tucked in and horns vertical. They then may lower their heads to the ground with horns pointing toward the opponent. When fighting, their horns interlock, and they engage in pushing or twisting. In all gazelle species, males establish territories during the breeding season, from which they actively exclude other males while females are receptive.
Males mark their territories with urine, dung, and secretions from their preorbital glands.
Birth occurs throughout the year, but coincides with the vegetation flush that follows rainy seasons. Young are born singly. The newborn lie outside the herd, hidden in foliage for the first few weeks after birth. The mother will come to nurse it, bleating softly to which the infant answers. Man has greatly reduced the number of many gazelle species.
