Sex, Age, Comment | Estimated some 40000 this evening passing by to their night roost. Strangely the majority of black birds this evening was BH Cowbird. The behavior was also different,with large groups of birds formatting a circling ball while descending to the surface of the lake to drink before continuing. | ||||||||||||
