I have been enjoying the beautiful pictures in my 2016 Audubon page-a-day calendar, but I am a little disturbed that one and maybe two of the first eight birds are misidentified. The bird labeled "Snow Goose" I think is actually a white domestic goose. The bird labeled "Great Blue Heron" looks like it might be a Grey Heron. No information is given as to where or when the photos were taken, but birds from around the world are included. Anyone have any thoughts?
