Take a walk across the mixed grass prairies of North Dakota during the spring and summer and you are likely to hear a series of short buzzing sounds emanating from a patch of western snowberry (what some people call buckbrush) or perhaps a thicket of some other shrubs. You may associate the buzzing with some type of insect, but it isn’t. It is the call of the clay colored sparrow. There it is again ... "Song of clay colored sparrow."
