In SW Miramar, early this morning, about 7 minutes after sunrise under a gray sky, an adult briefly appeared overhead between the treetops. I noticed that a string or line was streaming about 4-5 feet behind it. I was late with my camera and only captured sky and two partial images of the eagle in terrible light. I think it was the male (Pride), based on my impression of smaller size. This location is about 1 1/2 mile ESE of the Pembroke Pines nest and a common route used by the eagles on their way to the big (Lighthouse Island) lake in Sunset Lakes.
Not sure whether this is cause for concern. The eagle may be carrying a small dark object to which the string is attached. Alternatively it could have been snagged by fishing tackle. Please keep an eye out for it.
I have briefly visited the nest a couple of times this past week and always found it vacant with no eagles in sight.
