The Coast Miwok spoke their own Coast Miwok language in the Utian linguistic group. They lived by hunting and gathering, and lived in small bands without centralized political authority. In the springtime they would head to the coasts to hunt salmon and other seafood, including seaweed. Otherwise their staple foods were primarily acorns—particularly from black and tan oak–nuts and wild game, such as deer and cottontail rabbits and black-tailed deer, "Odocoileus hemionus columbianus", a coastal subspecies of the California mule deer, "Odocoileus hemionus". When hunting deer, Miwok hunters traditionally used Brewer's angelica, "Angelica breweri" to eliminate their own scent. Miwok did not typically hunt bears. Yerba buena tea leaves were used medicinally.
