All About Bears
Under ordinary conditions black bears display mutual avoidance of each other rather than territorial aggression. A sub adult female’s territory will overlap her mother’s range. Sub-adult males sometimes disperse over great distances, which help maintain the viability of the gene pool by reducing the incidence of inbreeding. When habitat becomes limited or degraded, sub-adult males may encroach on the territory of sub-adult females and force them into marginal areas near human population. This is precisely what happened in 1989 when 23 bears came into Albuquerque. All were sub-adult females driven from their range during a period of drought.
