Lower Redrock Lakes Montana 261. humpson June 20, 1932 sure that the eggs were dead, we took them. During the afternoon counted, definitely 11 swans (adults), and 4 cygnets on the Lower Lakes. Do not think that the Upper Lake birds were flying back & forth. Counting also the 8 adults & 3 cygnets of the upper lakes, there is a total of 19 adult swans and 7 cygnets actually seen on the 2 lakes. There maybe more.
