Black bears are capable of killing various livestock and poultry, including sheep, goats, swine, cattle, rabbits, turkeys, and chickens. Sheep accounted for most (90%) losses in Virginia but in Alberta cattle (mostly calves) comprised 81% of losses. Livestock depredations are comparatively uncommon in Massachusetts; 100% of livestock owners surveyed in 1990 indicated that damage was low or moderate with losses <$1000 per year. Livestock depredations have been widely reported throughout North America, but verification of kills is often lacking. Only 1 of 8 bears within sheep allotments in Idaho and Wyoming was a known predator. In one Maine study, 57% of sheep losses were fraudulent or undetermined. Typically, only a single animal or a few are killed; however, in one western state 230 sheep were killed. Numerous losses during a single instance may involve surplus killing (i.e., excessive multiple kills at one time). Although one hypothesis suggests that searching behavior (but not killi
