Yeah, they're more than just overgrown raccoons. A lot of black bear attacks happen in the spring before food sources become abundant. A lot of the fatal attacks are by rogue males as well, not just females defending their cubs. Sows will defend their cub(s) any time of year, but will often break off an attack once they've satified the protection instinct and return to their cub(s). A male bear that does attack is likely out to kill and eat you, period.
