Once a territory is established, it will remain with that tiger until its death. There is little overlap of territorial boundaries between adults of the same sex. However, a male's territory may overlap the territories of several females. Tigers can be tolerant of other tigers. Examples are several tigers gathering together to consume a particularly large kill, a mother with her young and a male and female staying together while mating.
Tigers communicate to one another by rubbing heads, roaring, purring and grunting.
Avoidance, however, appears to be the rule rather than the exception. A habitat of dense vegetation, with scattered prey living alone or in small groups, favors a predator that hunts alone. On the Prowl Tigers depend less on smell and more on keen eyesight and acute hearing to ambush and capture prey. Unlike lions that hunt in prides in open country, the solitary tiger prefers to hunt in the cover of dense foliage. When within striking distance, the tiger charges and grabs its prey.
