You have a California Prionus beetle, Prionus californicus, a member of the borer beetl group. They are among the largest beetles in the Western US. Though I couldn’t find any information on their noise making habits, I do know for a fact that other borers, including the red and black Milkweed Borer, Tetraopes tetraophthalmus, are capable of squeeking when handled. Here is some information I downloaded from another site: Range: California: coastal and inland valleys, foothills, and mountains to middle elevations. > Alaska, south to Baja
