Near Toledo, Ohio on the Maumee River I saw a very large bird, bald eagle size, circling over the river. For sure not a mature bald eagle and I don't think it was an imature either. It was whitish underneath with black wing tips from below. Also had a white back but dark wings from above. Appeared to have brown markings on breast though not in a pattern I could distinguish. Tail was light with a dark bar near the end. Need some ideas so I can look at pictures. My first though was an osprey, but didn't look like the pictures I've seen. Suggestions? Bill Quinlan
