Finally had several other views of it - gray body, chestnut wings, whitish under body. Black on head. Undertail black and white spotted. The birds gave low, guttural scold notes. Before leaving the area we had seen 3 pairs, some fairly close to us as we ate lunch. In willow-cattail slough border strip.
