Yellow-rumped? Even though no yellow is visible?
Not sure of this ID
song was Eastern Meadowlark
I guess the size is most like coopers but not 100% sure of this individual
I found this goose at my lake house in Mattoon, IL on thanksgiving break. I believe this was a mother goose because she was protecting some eggs near by. The goose was very timid and scared when we approached because of the eggs. She lived in a wooded area with a nest of twigs and her eggs.
