Voice - The call is a clear, whistled "bob-white" or "ah bob-white", with a rising emphasis on the "white". Also, it gives a whistled "hoy" or "a-loy-hee" and a variety of other chatty-like calls. The Northern Bobwhite is heard mostly from spring to autumn, calling from a favorite perch, but it also calls in winter, usually in the early morning or late afternoon.
