媒体文件注释
I recorded this as I observed the birds flying nearly directly overhead at about 200 feet above the ground.
观察细节
There were approximately 45 in the field behind our house. About mid day they flew up and circled for about 20 while above the house, calling almost non-stop. The birds were mostly light gray.
