Mahkwa Kiilhswa ‘Black Bear Moon’ is one of two lunar months named for the American black bear (Ursus americanus). It typically occurs between late December and early February in the Gregorian calendar. To the best of our knowledge, this month is associated with mature female bears giving birth to their cubs. Female American black bears have a litter of cubs every 2 years, and litters range from 1-5 cubs. Following birth, cubs stay with their mother for 1-2 years. Mahkooki ‘American black bears’ were an important source of food for Myaamia people, with bear tenderloin being a particular delicacy. Mahkwa also plays a prominent role in Myaamia aalhsoohkaana ‘Winter Stories.’
