I still do not have a definitive ID for the Cooper-Sharp-shin. However, I think we can agree that the following is about the Bald-headed Eagle pair on "Jim's" farm.
"Jim" told me that eagles have often checked out this osprey's nest in other Springs before flying further. However, this year, it looks serious. We shall try not to disturb them. However, I am sure we will drive by often in the coming months.
