Hi John,
I was one that disagreed with the Goshawk ID. The reason is I have photos
of an immature Cooper's from my back yard with what appears to be a fairly
distinct off white supercillium. I am very sure it came from a nest of
Cooper's that was just a couple blocks away and I had seen the young on many
occasions. Also if you do a google image search for immature cooper's you
will see many many photos of them with what appears to be a off white -
light tan line above the eye and extending back. I am far far from an
expert but have learned over time that it is impossible for Sibleys or any
other book to capture all plumages etc... in their drawings and photos
especially when it comes to immature birds or birds that have big
differences in breeding to non breeding plumage. I tend to rely more on the
photos I dig up from reliable sources on the web as long as there is more
than just one example.
Also while searching you find many discussions about the supercillium of
both species. Some saying bright white to pale on the Goshawk and others
mentioning pale on the immature Cooper's

The supercillium in Paul's photos looks pale to me or tan although somewhat
distinct. I would like to know what the records say about Goshawk sightings
in southeast Wisconsin. I have read up on them somewhat and thought they
were not migratory and only really move south when the food supply is bad
ie; during irruptions and mainly in the winter or late winter/early spring.
