The second bird was an overall dark brown except for a very small amount of white to whitish color at the base of the retrices. This bird had a lighter brown color to the back of the head and on the nape. There was no mottled effect as would be shown in an immature Bald Eagle. | The original documentation form event lasted from 10:00:00/10:30:00 approximately.
