Do male black bears kill cubs?
Male bears do sometimes kill cubs if they get separated from their mother. With only one cub to look after there is little worry for Lily. In general, male bears avoid females with cubs. It is commonly thought that males kill cubs to bring the female come into estrus — however, the common litter size in MN is 3 and a male would have to kill all 3 before the female would come into estrus.
