my 16 yr old son saw one in Taunton recently, i was a bit skeptical at first but he was pretty adamant that it was an eagle...after reading about the other sightings in this thread it looks like people are seeing them all over now...
There are a couple pairs around the Hanson/Halifax area. Been seeing them for the last three years or so. A couple around Oldham Pond at my daughters house in Hanson, and another pair over at Monponsett in Halifax.
