Thanks, Mark--
Yes, this is quite a distance from the nest. Since it is an adult with a white head, it is possible but somewhat unlikely to be one of the Pines Boulevard adults. The corner of Flamingo & Miramar Parkway is about 7.5 miles from the eagle nest. Their home range is said to be about a 2 mile radius from the nest, but this pair regularly forages in Sunset Lakes, about 3 miles from the nest.
If there are more sightings from that area I would suspect a new nest. We should keep an eye out for one in that general area. I am copying the Florida FWC for their information.
Thank you!
