The Maidu (Pujunan), including the Nisenan (Southern Maidu, Nishinam) and Konkau (Concow, Konkow), live in the drainage area of the Feather and American rivers in north-central California among other Indians and Whites. They spoke languages of the Maidu (Pujunan) family of the Penutian phylum. The number of Maidu today is not known, but may be over one thousand.
