Mahkoonsa Kiilhswa ‘Young Black Bear Moon’ (listen to the pronunciation on the Myaamia Online Dictionary) is one of two lunar months named for the American black bear (Ursus americanus). To the best of our knowledge, this month is associated with the emergence of American black bear cubs from their dens around this time. The start of Mahkoonsa Kiilhswa marks Weehki-kihkatwe ‘the Miami Lunar New Year’ (listen to the pronunciation on the Myaamia Online Dictionary). During some years, the maple sugaring season begins during Mahkoonsa Kiilhswa; in general trees and animals begin the slow process of waking up as peepoonki ‘winter’ ends.
